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
