pressure still

The pressure distillation could get fine result of energy saving according to the analysis of evaporate latent heat,heat capacity and utilization water resoures in the system.

通过对蒸发潜热和热容的变化 ,水资源利用的分析 ,提出了加压蒸馏可收到节能降耗的良好效果 ,同时提出加压蒸馏应注意适度选择优化工艺设计参

In thispaper,the effects produced by using pressure distillation technology in acetaldehyde preduction and theresults of energy conservation as well as the choices of suitable operation conditions are briefly intro-duced.

将加压蒸馏技术应用于乙醛生产，节能效果显著。
