摘要
对引进的De-Smet浸出车间混合油蒸发、溶剂冷凝回收、尾气回收及水化脱胶系统的工艺配备情况及操作过程进行了介绍。整个蒸发系统采用全负压工艺技术,充分考虑余热利用,降低蒸汽消耗。从使用3年的情况来看,脱胶油含磷量和残溶达标,预处理车间和浸出车间整条生产线蒸汽消耗为265 kg/t,溶剂消耗小于等于0.8 kg/t。
The process and operation parameters of De - Smet evaporation, solvent recovery, vent recovery and hydration degumming system were introduced. The production practice for three years showed that the phosphorus content and residual solvent in the degummed oil reached the standard, the steam and solvent consumption in the production line of pretreatment and solvent extraction plant were 265 kg/t and less than 0.8 kg/t,respectively.
