METHOD OF DETOXIFICATING WASTES CONTAINING LESS THAN 50% LIQUID AND/OR PASTY HYDROCARBONS Russian patent published in 2007 - IPC C08J11/00 A62D3/00 

FIELD: detoxification methods.

SUBSTANCE: invention relates to oil and gas industry and can be used in other industry fields where long-term storage and accumulation in slime collectors of considerable amount of oil-containing waste containing liquid and/or pasty hydrocarbons. Detoxification method involves supplying, into mixer, burnt lime and a modifier, namely technical-grade fat, amount of which constitutes 5% of the weight of the burnt lime. Thereafter, supplied materials are spread across all the length of the mixer and waste containing less than 50% liquid and/or pasty hydrocarbons is added to the mixer in amount that waste-to-burnt lime weight ratio would be between 1:1 and 1:2. Resulting mixture is mixed and water is introduced to slake lime. Thus obtained mix is conveyed from mixer to mix purification unit.

EFFECT: lowered waste danger class and improved environmental condition with respect to dust, light hydrocarbon fractions, and organosulfur compounds.
