| titleOfInvention | A kind of akali sulphide black liquor, liquid caustic soda coproduction sodium bicarbonate, sodium chromate, akali sulphide technique |
| abstract | The present invention provides a kind of akali sulphide black liquor, liquid caustic soda coproduction sodium bicarbonate, sodium chromate, akali sulphide technique: using akali sulphide black liquor as material liquid, by obtaining weight alkali liquor, hydrogen sulfide gas and sodium bicarbonate solid with carbon dioxide reaction；Weight alkali liquor to subsequent cycle and akali sulphide grey black leaches to obtain the akali sulphide black liquor；Hydrogen sulfide gas and liquid caustic soda react to obtain Gas with Sodium Sulfide Solution；Gas with Sodium Sulfide Solution is concentrated by evaporation, and cooling obtains akali sulphide；Sodium bicarbonate solid and chromite roast to obtain sodium chromate.Akali sulphide black liquor of the present invention, liquid caustic soda coproduction sodium bicarbonate, sodium chromate, akali sulphide technique, technical process simple, product quality and added value high, comprehensive energy consumption and production cost low, three-waste free discharge the features such as lower with material quality and price. |
