FIELD: technological processes.
SUBSTANCE: invention relates to method of filter-aid regeneration used during process of oil winterizing. The method comprises the following stages: a) regenerating oil circulation in the circulation circuit through the filter cake of the depleted filter-aid at a temperature from 40 to 100°C with ratio of regenerating oil/depleted filter-aid (vol./Wt.) from 0.3/1 to 12/1, b) extraction of the regenerating oil from the depleted filter cake of the depleted filter-aid, c) separation of the regenerated filter-aid.
EFFECT: possibility of multiple regeneration of depleted filter-aid and reduced amount of solid wastes generated during the process of oil winterizing.
