摘要： 根据闪蒸技术原理与特点,在精制甘油生产的工艺与相关设备设计中,用闪蒸代替传统反应釜间歇加热脱水工艺,使生产效率有了很大的提高,将粗甘油的含水率从8%降至0.2%,能源消耗降低,操作简便,具有很大的优越性。并指出现有设备设计存在的不足与改进方法。

关键词: 闪蒸, 甘油, 脱水

Abstract: According to flash-vaporizing principle and characteristics, the flash-vaporizing techniques rather than steam-jacked kettle for evaporation in glycerin production were used. The production efficiency has been greatly improved. The moisture of the crude glycerin was reduced from 8% to 0.2%. The process has low energy consumption, easy operation and great advantages. The shortco mings in the design and improved plan were provided.

Key words: flash-vaporizing, glycerol, dehydration
