Abstract

Способ получения хлористого аммония путем переработки фильтровой жидкости содового производства, включающий нагрев фильтровой жидкости, упаривание полученного раствора в вакуум-выпарных аппаратах, выделение кристаллов хлористого аммония путем охлаждения упаренной жидкости, отделения кристаллов хлористого аммония и сушки, отличающийся тем, что к фильтровой жидкости добавляют неионогенный ПАВ в количестве 0,0005-0,001 мас.% и соляную кислоту до достижения показателя рН реакционной массы 6,0-6,5, а упаренный раствор охлаждают до температуры 10-15°С.A method of producing ammonium chloride by processing a filter fluid of soda production, including heating the filter fluid, evaporating the resulting solution in vacuum evaporators, isolating crystals of ammonium chloride by cooling the evaporated liquid, separating crystals of ammonium chloride and drying, characterized in that non-ionic is added to the filter fluid Surfactants in an amount of 0.0005-0.001 wt.% And hydrochloric acid until the pH of the reaction mass reaches 6.0-6.5, and one stripped off solution is cooled to a temperature of 10-1 5 ° C.
