四效逆流降膜蒸发工艺介绍及对比

Introduction and comparison of four-effect countercurrent falling film evaporation process

介绍了四效逆流降膜蒸发工艺,通过与传统二效蒸发、三效蒸发工艺比较,四效逆流降膜蒸发工艺能有效降低烧碱蒸发过程中的蒸汽消耗,达到节能降碳目的。

This paper introduces the four-effect countercurrent falling film evaporation process.Compared with the traditional two-effect evaporation and three-effect evaporation process,the four-effect countercurrent falling-film evaporation process can effectively reduce the steam consumption in the process of caustic soda evaporation,save energy and reduce carbon.
