Feasible analysis on comprehensive utilization of recovered brine of diaphragm and ionic membrane caustic soda 离子膜碱与隔膜碱回收盐水综合利用可行性分析
The heat in low-pressure steam which was discharged from the tail effect of caustic soda evaporation procedure was recovered by a set of absorption heat pumps and was used to preheat brine, and then the consumption of steam decreased. 介绍了采用一套吸收式热泵回收烧碱蒸发工段尾效排出的低压蒸汽所带出的热量,用来预热盐水,达到降低蒸汽消耗的目的;
The comprehensive utilization of recovered brine in diaphragm and ionic membrane caustic soda process were analyzed. Through design optimization of process, adding rate of bittern under the same scale and capacity from principles were about 100%, and economic benefits was obvious. 从理论上对离子膜碱与隔膜碱工艺装置回收盐水的综合利用可行性进行了分析,通过工艺优化设计,在同等规模产量的情况下掺卤比例理论上可接近100%,经济效益比较显著。
