摘要
对草甘膦生产中三乙胺回收工艺改进后 ,可节省三乙胺单耗 8kg ,塔顶回收率达 98%。将蒸发浓缩工艺的设备材质由不锈钢改为碳钢 ,并取消真空泵和循环泵 ,从而简化工艺、节约投资。
Technological improvements made in triethylamine recycle process in glyphosate production can save 8 kg triethylamine per kg gluphosate and the recycle rate at tower top can reach 98%. The shift of the material for the equipment in evaporation process from stainless steel to carbon steel and the removal of vacuum pumps and recycle pumps have simplified the process and saved the investment.
