METHOD OF RECOVERING DIETHYLAMINE FROM FILTRATE LIQUID IN SODA PRODUCTION

摘要

FIELD: soda production. SUBSTANCE: filtrate liquid is brought in contact with inert heat carrier taken in quantity 10-15% of that required to recover diethylamine. Decarbonized liquid obtained is mixed with lime milk and hold in reactor-mixer until diethylamine to calcium oxide molar ratio in outlet material is attained. As inert heat carrier not containing diethylamine and carbon dioxide, steam supplied into distillation column is utilized. EFFECT: enhanced efficiency of process. 2 cl, 1 dwg , 1 tbls
