Summary:FIELD: dehydration of heavy oils and bitumens. SUBSTANCE: method is carried out by filtration through drying filter. Natural leather which is placed on perforated plate being set to vertical wall of settling chamber at angle of 20-30 degrees is used as said drying filter. Aqueous-oil emulsion having temperature 80-90 C is fed on drying filter, said settling chamber is inside evacuated to 30-50 mm Hg. Thus up to 95 % of water are separated of aqueous-oil emulsion. EFFECT: decreased energy expense; simplified the method. 1 tbl, 1 dwgd
