浅析多效蒸发在烧碱浓缩中的应用

Utilizing of Multiple-effect Evaporator Method in Caustic Soda

节能减排是石化行业势在必行的措施,蒸发是一个能耗很高的化工单元操作,为了降低能耗,可采用多效蒸发。多效蒸发在溶液浓缩是一种重要的能量利用与回收工艺,其最大的优点是多次利用二次蒸汽的汽化和冷凝,可以显著减少新鲜蒸汽消耗量。文章从节能机理出发,简要介绍了多效蒸发在烧碱蒸发工艺中的应用。

Energy conservation is imperative measures in petrochemical industry,the evaporator is a high energy chemical unit operations,in order to reduce energy consumption,we can use the multi-effect evaporation.Multi-effect evaporation or solution concentration is an important energy use and recycling processes,its biggest advantage is that multiple use of secondary steam vaporization and condensation,can significantly reduce the consumption of fresh steam.this departure from the energy-saving mechanism briefly introduce the utilizing of multi-effect evaporation in caustic soda.
