I-20 Industrial Oil: Filter Prices

I-20 industrial oil is used for the lubrication of the most common industrial assemblies and components that do not require oils with special anti-oxidation or anti-corrosion properties.

Buying the oil is not the only expense.  During operation, the oil’s quality must be monitored and the oil should be purified and regenerated when necessary.  The foremost factor in selecting a purification method is the price to quality ratio.

One of the methods of purification that we would like to discuss today are filters and the specifics of their practical use.

Filters have various designs.  Selection of a filter configuration depends on operating conditions and the requirements to maintain the oil’s purity.  Filters are used practically in all stages of production including the storage and transportation of the oil.  Filters are installed in oil storage facilities, oil refineries and in equipment and machinery using oil.

Transportation, storage, and filling of industrial oil I-20 is performed with equal element filters.  This type of filter is of simple design and can be operated in a wide range of operating pressures.  The main drawback of the equal element filters is the need to disconnect them for filter element cleaning or replacement.

In general, oil filters are cylindrical and vary in design of filter element fixture, the number of filter elements, and presence of safety valves.

The need to change the filter arises when the filter becomes contaminated as indicated by the pressure difference on the filter.  This difference is measured by two manometers.

The design of the filter is chosen depending on where the filter will be installed.  Oil refineries usually filter industrial oil before shipping the oil to the customer or wholesale distributor.

Filters used in storage parks must have high throughput.  Their weight and dimensions do not matter much since the filters are stationary.

Along with fabric filter elements, there are also metal mesh, felt or fiberglass filter elements in the oil industry.

The requirements to filters used for oil in stationary oil storage facilities are similar to those installed in oil refineries.

The main problem with a disposable oil filter is the limited service life.  Filter media becomes saturated with contaminants increasing the pressure drop to maximum limits.

Lube oils are filtered mostly through disk filters that can only assure coarse filtration by removing particles larger than 70 microns.

During filtration of thickened oil, the filter’s throughput may be lowered by as much as 30-40% compared to oil without thickeners.

For operation in low temperatures, filters are equipped with jackets with steam or a water inlet for heating.

Modern Views of Industrial Oil Filtration

What Are the Types of Industrial Oil?

Industrial oils include a great amount of different oil products such as:

•    motor oils (oils for gasoline- or diesel-powered engines);
•    oils for air-engine;
•    transmission oils;
•    hydraulic oils
•    fuel oils (turbine, insulating, compressor oils); and
•    industrial oils.

Depending on the purposes and the application area, each type of oil performs different functions.  In general, insulating fluids are intended to isolate, reject heat and to quench an arc in electrical appliances.  Industrial Oils are used to lubricate working parts of industrial machines, transfer heat from one system to another, reduce the wear and friction rate as well as transfer heat.  Motor Oils serve as the lubricants for piston and rotary internal combustion engines and perform many of the same tasks as industrial oils.

Oil Filtration: Major Motives

The statistics show that about 80% of all oil-filled equipment failures are caused by contamination of industrial oils.  In general, oil is contaminated by such substances as dust, metal chips, rubber crumbs, sand, and other undesireable contaminants.  Particles of less than 2 microns (resin or oxidation products) constitute the greatest danger to the operation of high tech equipment.  Water that got into oil from the atmosphere or by condensation can result in corrosion, rapid wear and accelerated aging of oil. As a result, the operational reliability of machines and their parts are reduced significantly.

To prevent such undesirable consequences, the qualitative performance characteristics of oil should be regularly tested to determine if there are mechanical impurities.  Oil is recommended to be tested both before filling the equipment and during maintenance of the equipment using special devices.  If the performance characteristics turn out to be below the acceptable level, it is recommended to carry out a preventive filtration or what is commonlu referred to as “Oil Processing.”

Oil Filter Classification

Oil filters are divided into different groups according toa very specific classification criteria.  There are built-in and stand-alone filters depending on the place they are mounted.  The built-in filters are mounted into the main part of the oil system and for the most part operate under high pressure.  Accordingly, the stand-alone filters function separately from the oil/lubricating system.
Depending on the application, there are metallic, paper and fiberglass filters.  Metallic Filters work according to the principle of surface filtration.  Usually, they are made of stainless steel that makes it possible to apply them when working with hydraulic and lubricating oils.  The filtration fineness is between 25 and 80 microns.

Paper Filters are used for deep filtration and the filtration fineness is between 10 and 25 microns.
Fiberglass Filters also work according to the principle of deep filtration.  This type of filter distinguishes itself through a high dirt-holding capacity and good filtration fineness even under heavy pressure.

Disposable and non-disposable filters have obtained a wide circulation and popularity in industry. Disposable filters are used so the filtered oil will meet the desired purity class.  When the filter is no longer able to filter oil, it should be replaced with a new one.

The difference between disposable and non-disposable filters is that when non-disposable filters become saturated with contaminants, they are not replaced but cleaned of impurities.  The disadvantage of such an approach is that filters may need frequent cleaning.  It is also worth mentioning that modern filters are not able to remove impurities with the size of between 1 and 5 microns though they constitute about 70% of all possible impurities.  Even so, filters are much in demand at small machine and tractor stations or service stations.  Such methods of cleaning is unprofitable for medium and large industries: the more used oil they have the more expensive the cost of replacing and/or cleaning the filters becomes.

But there exists an optimal and profitable solution!

GlobeCore has developed its CFU line of units to solve the problem of industrial oil filtration.  Such substances as mechanical impurities, carbon black, water-soluble acids, and alkalis are removed from industrial oils by the GlobeCore CFU units.

The following is the list of benefits of using GlobeCore’s filtration and processing equipment:

•    reduces the wear and extends the service life of oil and oil-filled equipment;
•    increases the time necessary between periodic testing;
•    reduces the amount of unscheduled downtime of equipment;
•    increases productivity;
•    preserves oil’s performance characteristics; and
•    reduces the negative impact on the environment.

Being mobile, GlobeCore’s equipment allows for industrial oil processing directly at the remote operating sites.

It is worth mentioning that all benefits listed above contribute to significant cost reductions.

Industrial Oils and Purification

Industrial oils are used as a lubricant reducing friction and wear of parts and components in various industrial machines.  The main functions of this type of oil is anti-corrosion protection, dissipation of heat from friction parts, removal of contaminants and reduction of foaming.

Industrial oils can also be used as the base for hydraulic fluid, as well as grease, that extends durability and service life of industrial equipment.

Despite the fact that practically all industrial oils are thoroughly tested in laboratories before dispatch to the user, the oils will become contaminated during use and operation.  Industrial oil, just as with any other oil, can become contaminated by atmospheric oxygen, water and particulate matter.  Interaction with aggressive media may accelerate oil oxidation that is accompanied by the accumulation of even more unwanted contaminants in the oil.

Saturation of oil by contaminants degrades the oil’s performance.  Due to aging and contamination,  industrial oils lose the ability to efficiently dissipate heat and protect equipment from corrosion.

It would seem that the aging process is natural and nothing can be done about it except replacing the used oil with new and disposing of the old oil.  A practical operator however, will be concerned by the additional costs of used oil disposal, as well as the frequent cost of oil changes.

Fortunately, aging of oil is not all that critical with the advent of modern additives and oil processing equipment.  The aging process therefore, can be significantly slowed and the service life of the lubricating oil can be significantly extended.

It is however, necessary to regularly take oil samples to know and understand the oil’s condition and to detect and identify the contaminants degrading the performance of the oil and to purify the oil in a timely manner.

GlobeCore is one of the leading manufacturers and suppliers of industrial, turbine and dielectric insulating oil purification systems.

The CMM-CM type units and  CFU-M filter carts made by GlobeCore are successfully operated in more than 70 countries around the world.  They are efficient for the purification and regeneration of industrial oils.

The ability to purify and regenerate industrial oil was made possible by using modern technologies and maximizing and customizing the processing operations for the individual client.

The CMM-CM units are designed for removal for water and solid particles from oil by using a special zeolite sorbent and subsequent reactivation of this sorbent in the system.

The CFU-M filtration carts are designed for removal of solid particles from industrial oil.  These units can purify the product in one cycle.

Both types are simple in service and operation and facilitate a significant extention of industrial oil service life cycle.

Industrial Oil: Wholesale or Retail?

The volume of oil required to be purchased is defined by the needs of the company or the facility.  Normally, a large amount of oil is purchased wholesale, while a smaller amount needed for the replacement of oil fir one or several machines, is usually purchased retail.

Based on price, it would seem that wholesale purchases are better for your company financially.  The price of a large batch of oil per liter purchased wholesale will be lower than purchasing smaller retail volumes pre liter.

There are however, problems with large amounts of oil.  Wholesale volumes of oil must be stored somewhere. Industrial oil is obviously sensitive to various contaminants such as water, particulate matter and other unwanted contaminants.  Apart from allotting storage facilities, the oil also requires constant monitoring of purity and and water content.

Purity of industrial oil purchased wholesale or in smaller retail batches can be ensured by two methods:

  • Prevention of contamination in storage; and
  • Purification of contaminated oil.

Both include a whole range of measures.  As stated above, purity of industrial oil can be ensured by prevention or purification, but the best results are achieved by combining the two.  This also allows savings of money since preventive measures require quite less investment than actual purification and regeneration.

Prevention alone however, cannot maintain industrial oil’s purity in the long run.  It requires a complex approach to transportation and storage using the following equipment:

  • air-tight tanks;
  • equipment made from non-corroding materials;
  • correct temperature in storage and transportation;
  • and the use of inert gases to fill gas space.

This increases the cost of prevention.  The goal therefore, is to reduce the amount of contaminants as much as possible in the oil going to purification devices, which finalize the required purity of the product.

The following systems from GlobeCore GmbH are recommended for the purification and regeneration of industrial oil:

●      Mobile oil unit CММ-1.7 CM;
●      Mobile oil unit CММ-3.5 CM;
●      Mobile oil unit CММ-5 CM;
●      Filter cart CFU-0.8М;
●      Filter cart CFU-1.7М, (CFU-4).

Industrial Oil Sales: Preserving the Oil’s Performance Characteristics

So, you have decided to sell industrial oil?  Let’s assume that you already have found a storage facility for the product.  One thing remains however, knowing what the consumer needs and how to provide that need.

Besides better terms of supply, lower price, and various discounts, the client is mostly interested in the quality of the product.  Industrial oil quality in our case.  The quality is a combination of many parameters and characteristics that must not fall below regulated specifications during storage, transportation and operation.

Let us look into the characteristics, which define the quality of industrial oil and are important for the client’s choice:

  • Viscosity.  This is the first thing to consider about oil.  It is very important for the use of the majority of industrial oils.  When friction parts are designed and calculated, the parameter taken into consideration is the dynamic viscosity of the oil.  This is a regulated parameter of all oil made from crude base stock.  Dynamic viscosity used be defined at between 50ºС/122ºF and 100ºС/212ºF. That has changed and now all measurements are made according to ISO 3448-75 (instead of measuring viscosity at 50ºС/122ºF, the reference temperature is now 40ºС/104ºF).  When choosing industrial oil, the buyer usually considers three critical viscosity values: optimal at working temperature, minimal at maximum working temperature and maximum at the lowest working temperature;
  • Pour Point. This parameter is defined by testing a sample of the oil.  The Pour Point is the lowest temperature that the oil will continue to flow.  This temperature does not entirely indicate the dynamics of the oil in operating conditions at low temperatures.  That is shown better by actual viscosity at a given temperature. To reduce the pour point of industrial oil, it is mixed with special additives. This parameter is meaningful to the buyer planning his storage operations, dispatch, and draining and for using the oil in low temperature environments;
  • Flashpoint. This is the temperature at which the vapor of the oil can form a flammable mixture with the air. It defines the relative fire hazard of the oil and shows the presence of volatile fractions within it.  It is measured in special open or closed type devices;
  • Ash content. This parameter indicates the amount of non-organic contaminants left after burning a sample of the industrial oil. It is expressed in percentage of weight.  If ash content of oil without additives is too high, it indicates insufficient purification.  In most cases, ash content of industrial oil is from 0.002% to 0.4%;
  • Content of particulate matter, solvents, water, water-soluble acids and bases. This indication is extremely important in controlling the oil quality after production as well as determination of its further usability.  Mobile oil purification units for treatment and regeneration of oil can significantly increase the service life of the oil and improve reliability of machinery;

In practice, GlobeCore products are used for the purification and regeneration of industrial oil.

  • Color.  The color is a visual indication of the purity of industrial oil.  It also allows the buyer to make a judgment on the oil’s origins.  Keep in mind that some additives can make the oil darker.  If the color of the oil changes during use however, this is an indirect indication of its oxidation and/or contamination;
  • Acid number. Knowing this important neutralization number allows the buyer to determine the oil’s purity as well as the stability in use and in storage.  Additives can increase the acidity of the oil, but can also increase the stability of oil for long term use and storage;
  • Sulfur content.  The amount of sulfur initially depends on the amount of sulfur in the crude base stock the oil was blended from and the degree of purification and refinement.  After purification of industrial oils made from sour crude, sulfur remains in the oil in organic compounds and under normal conditions does not cause corrosion of metals.  Sulfur may become aggressive in elevated temperatures.  The content of sulfuric compounds is higher in oil with additives. This is due to the fact that additives containing sulfur are mixed with industrial oil to increase their lubrication qualities.

Complete purification of I-12 industrial oil

I-12 industrial oil is a general purpose oil with no additives. It is made from sweet crude by selective purification.

This oil is used for lubrication of bushings of straight bar and linking machines, spindles of metal cutters, bearings of low power electric motors, and as an operating liquid in positive displacement of hydraulic drives operated indoors.

Combined purification methods of I-12 industrial oil are based on simultaneous influence of several electrical fields or a field with filtration.

The principle of combining electric field influence and centrifical force is implemented in cyclone separators and centrifuges equipped with a special electrical device.

By design, a triboelectric centrifuge purifier is a multifoil rosette with two chargers that create opposite charges in the industrial oil.  The passes through the swirler in a translational-rotational movement.  It them passes the oil through a circular ring space. Due to friction with barriers, contaminants become oppositely charged. Centrifugal force moves particles with a positive charge to the outlet wall where they are coagulated with negatively charged particles.  The charges are neutralized in the coagulated particles.

Then by the force of gravity and inertia, the particles are deposited in a special settling tank.

Comparing hydrocycling efficiency with that of a similar machine equipped with chargers, the chargers are 40% more efficient on average.

When using centrifuges with electrifying devices, the electric field may be obtained by voltage from an external source or by a triboelectric effect.  The triboelectric effect occurs due to rotor friction against special bars.  The rotor is made from a special dielectric material. (Plexiglas, PTFE, or some other dielectric material )

It is also possible to combine centrifugal force with a magnetic field.  It is done by installing permanent magnets into centrifuge systems to capture ferromagnetic particles. Diamagnetic and paramagnetic contaminants are only influenced by the centrifugal force.

The most widespread of combined industrial oil purification systems are devices combining elecrtric fields and filtration effects.  These include magnetic filters, filtering centrifuges and vibration (acoustic) filters.

In centrifuge filtration, the centrifuges operate at relatively low rotation speeds. Contaminants may be removed from the rotor either continuously or occasionally.

A magnetic filter is free from such a disadvange of magnetic purifier as selective removal of only ferromagnetic particles.  Such devices, beside permanent magnets, use special filters capturing non-magnetic contaminants.  An additional filter element (usually a metal mesh) protects the surfaces of the magnets from tar, sediment and other products of hydrocarbon oxidation.

In vibration filters the oil passes through a vibrating porous membrane.  The vibrations prevent sedimentation of contaminants on the surface and reduce hydraulic losses, increasing the filter’s service life.

It should be noted that the combined methods of purifying oil products are not widely used at this time due to the complexity of purifier design.

Oil filtration

During operation, transformer oil accumulate contaminants, which can form various chemicals. These substances reduce the oil’s performance and are, of course, undesirable.

Operation of the transformer becomes unstable. To prevent this, transformer oil is filtered and purified. Some of the methods are discussed in more detail below.

The first stage of transformer oil purification is mechanical. This is a superficial treatment to remove particulate matter and water. The next step is deeper purification performed in vacuum with heating.

The first two stages are, in fact, preliminary. The main process involves various chemicals.

One of the methods is purification of oil with a 98% sulfuric acid solution.

In comparison to other chemical purification methods, the use of sulfuric acid has a significant drawback. Beside reacting with the contaminants, the acid also adversely influecnes the structure of the oil, making it somewhat unstable. Additional processes are required to resolve that problem.

The nature of selective purification is evident from the title. Speical solvents are introduced into the oil to remove specific impurities.

De-waxing is another widely accepted process. In this process, oil is treated with special solvents: acetone, toluene, bensol etc, to remove solid contaminants.

It should be noted that chemical methods influence oil’s stability, but extend the oil’s service life at the same time.

It should also be remembered that any purification process should end with finishing purification, closing the cycle of oil processing and filtration. This is usually done by contact method.

This means that the oil is mixed with special materials, usually clay or bleaching earth. The materials are then mixed and heated. Heating facilitates acviation of all sorbents in the clay.

These absorbents capture contaminants. Deep filtration separates oil from the clay. When selecting adsorbent, it is necessary to pay attention to the content of moisture. It should be suffucient to make production efficient and to make processed oil compliant with specifications.

The most interesting technology today involves the use of bleaching clays (Fuller’s earth). Globecore manufactures a range of CMM type units for filtration of various oils with the use of Fuller’s earth. The advantages of the design are the ability of multiple reactivation of the sorbent, mobility, simplicity of operation and high quality of the output product.

Downtime is significantly reduced by the ability to reactivate the sorbent without the need for frequent replacement, thus increasing process efficiency.

Expert Opinion about the Classes of Hydraulic Oil Purity

Preventive Maintenance to Avoid Corrective Maintenance

Reliable operation of hydraulic equipment, widely used in various industrial facilities, depends mostly on the quality and purity of the internal cooling and lubrication oil.  Industrial machines normally operate under heavy loads and sometimes they operate under very difficult environmental conditions.  Regular maintenance of industrial equipment therefore, can allow maintenance personnel to detect possible equipment malfunctions in a timely manner.  The the essence of Preventive Maintenance is the avoidance of having to perform Corrective Maintenance.

The Problem

The presence of solid particles in oil and hydraulic fluids can quickly degrade the oil and the fluids in your hydraulic equipment.  Also known as particulate matter, among such particles, 70-85% are quartz,  10–15% are aluminum oxide, and  5–10% are iron oxide.  Contamination of hydraulic oil also disrupts the operation of your safety and regulation valves besides causing damage to your hydraulic system.

Although replacing used and/or contaminated oils and fluids is helpful, the complete replacement of oils and fluids is not a complete solution.  That is because the hydraulic system itself is most likely contaminated by metals and sludge.  These “remain behind contaminates” will actually contaminate fresh oil as soon as it is placed into the hydraulic system thereby negating most of the benefits of replacing the oil.  The new oil can also be contaminated during incorrect transportation, storage, handling, and filling of equipment.

Another important point, with regards to your maintenance program, concerns the filtering system of your hydraulic equipment.  The filters built into the hydraulic systems cannot, and do not ensure the required purification of oil circulating in your hydraulic system.

Oil purity class is not an indication of its compatibility with certain industrial equipment types.  Also, a specific purity class cannot give a precise answer as to the oil’s reliable operation.  Equipment loads will always have a direct influence on the rate of degradation of the oil.

The Solution

For reliable operation of hydraulic fluid systems and for the prevention of malfunctions caused by contaminated and degraded oils and fluids, it is necessary to use hydraulic oil purification equipment as part of a comprehensive scheduled maintenance program.

Selection criteria of such systems include consideration of the following attributes: (1) low filtration and regeneration costs; (2) reduction of repair and maintenance costs; (3) high purity level of the processed oil; (4) removal of sludge and contaminants from oil tanks and equipment reservoirs; (5) flexibility through a mobile or stationary design; and (6) compliance with international fire and health regulations.

The Best Solution

In order to provide the hydraulic equipment industry with machines that meet the requirements of the above listed criteria, GlobeCore has developed its line of UVR type units for oil purification and regeneration.  These plants are an efficient one-stop solution for a whole array of filtration and service equipment problems.  One GlobeCore UVR unit on a mobile platform can quickly service several machines regardless of location.  It can easily move around your facility and does not require readjustment for different kinds of oil or equipment.

The Problem

Disposal of waste oil is becoming less and less common.  According to the latest expert conclusions, a large amount of waste oil products are constantly being generated in many industrial applications.  This rise in industrial waste oil has led to increases in handling and disposal costs and fines for violations of environmental regulations.

The Solution

GlobeCore offers an excellent solution to the problem.  The GlobeCore Process is now available for the complete restoration of used oil used in commercial applications.  The customer will no longer have to  pay for oil disposal, oil handling and for environmental licenses.  Instead, the customer can now reuse the what used to be a waste product.  A unique oil purification and regeneration process is used in a wide range of GlobeCore products.  The GlobeCore Process is environmentally sound because it does not cause the emission of unwanted gases, liquids and solid materials into the environment.  The use of the GlobeCore Process  facilitates up to a 95% conversion rate and that equates to a tremendous saving for your company in time, labor, oil and money.

GlobeCore has a line of equipment intended for the purification and regeneration of used industrial oil by removing solid particles, water, and other contaminates.  The process produces oil color improvement due to the removal of oil aging products, unwanted additives and finely dispersed asphaltenes.  The GlobeCore machines are quite simple and easy to operate.  They do not require complex adjustments and enjoy the competitive advantage of high mobility and the use of special self-reactivating sorbents for the regeneration of fluids.

Up to 90% of tar, asphaltenes, carbenes and carboids are removed from the used oil in the process of purification with mild effect on the oil’s additives.   Various solid particles and water are removed entirely with complete restoration of the oil to it’s original specification and color.

Complete GlobeCore plants may be used for the filtration and adsorption process of various types of oils, including hydraulic fluids and industrial oils.  The GlobeCore systems does not require readjustment for various oils.  They also do not require filter replacements since the regeneration and adsorption elements automatically reactivate themselves after each cycle of oil restoration/regeneration has been completed.

The uniqueness and affordability of the GlobeCore Process units makes them an excellent and cost effective investment for your company.

The laws of hydraulic oil purification

Oils and other operating liquids, used as lubricants and coolants in various industrial equipment, are prone to degrade under the influence of elevated temperatures, pressures or flow. The functionality of oils depends on viscosity, oxidation stability and purity, lubrication capabilities, corrosion and emulsification. The difference of hydraulic oils from other oils is the relatively higher viscosity of the oil for high pressure hydraulic actuators. High viscosity makes operation of equipment unsafe or impossible. On the other hand, to ensure efficient operation of the systems, oil viscosity must exceed 20 cSt. Otherwise the pumps will experience increased wear, causing rapid loss of efficiency.
