| Abstract: | The operation pressure of cyclization towers is changed from positive to negative and partial heat from waste water is recovered,because the amount of steam consumption in the cyclization process of epoxy chloropropane production by dichloropropanol is large and the content of COD from waste water is high.Therefore,the cyclization yield is increased,steam consumption is decreased,COD content from waste water is reduced and the aim of energy-saving and environmental protection is achieved. |
