SEPARATION METHOD Russian patent published in 2015 - IPC B01D3/06 B01D1/16 C02F1/06 C02F101/16 C02F103/20 

FIELD: chemistry.

SUBSTANCE: inventions can be used in chemical and energy fields, as well as in field of organic wastes recycling. Device for separation of ammonia from fermentation liquids or fermentation residues on installations for biogas production includes flash evaporator F, connected with fermenter (a) or with storage place of fermentation residues, for substrate supply by pipes (1, 2, 3, 4, 5, 6). Vapour from flash evaporator F is discharged, and hot liquid phase from pipelines (7, 8, 9) is either returned by pipeline (11) into fermenter A or to storage place of fermentation residues, or supplied by pipeline (10) into second fermenter (I), to storage place of fermentation residues or into additional reservoir. Admixture compartment, connected with heat-exchanger D for liquid substrate components from one side, and by pipeline (22) with the second fermenter I for solid substrate components, from the other side, is provided in pipeline (2, 3) from fermenter A.

EFFECT: inventions make it possible to increase exploitation stability, oxidative capacity and output of methane on installation for biogas production, as well as to reduce heat-productivity of the process.
