During transformer oil purification, not only adsorption, but also other processes such as capillary condensation, chemisorption, flocculation, coagulation have a great impact on the final product.<\/p>\n
Very often, so-called Fuller’s earth or Fuller’s Earth filters are used as bleaching clay. \u00a0Sorbents, applied for transformer oil reclamation, \u00a0should meet the following requirements:<\/p>\n
(1) silic acid content in the dry product no less than 32.5%; content of calcium and magnesium no more than 2.2%;<\/p>\n
(2) the packed density of grit is no more than 0.65 g\/cm3;<\/p>\n
(3) the acid number of waste oil should be reduced by 45% per day;<\/p>\n
(4) the size of grit grains is 3-7 mm;<\/p>\n
(5) no more than 5% of grit grains with the size less than 3 mm;<\/p>\n
(6) no other impurities; and<\/p>\n
(7) moisture content is no more than 10%;<\/p>\n
Bleaching clays may be used both for continuous oil regeneration in transformers with a dehydrating filter breather and for the restoration of oil discharged from power equipment (contact method).<\/p>\n","protected":false},"excerpt":{"rendered":"
