回收效率低或设备出现问题

低温甲醇洗,大连理工的

可能导致的因素有,气提氮量过大,水洗塔洗涤水量不够,
Reply #52018-08-05
我觉得是尾气洗涤塔气液比过大,以及洗涤液温度偏高!1.可以减少气提氮气量,减少尾气量(但不利于甲醇再生);2.增大尾气洗涤塔脱盐水用量(但增加甲醇水分馏塔负荷);3.想办法降低洗涤用脱盐水温度!

有几种可能:1、脱盐水温度高;2、脱盐水用量小;3、尾气中甲醇含量高;4、塔盘有问题造成接触不充分,吸收效果不好。

塔内件检修的时候是不是动过?,再者再吸收塔上部液位过高或压力过高

楼主给的信息太少。检修了哪台设备?尾气洗涤塔检修没有?尾气甲醇含量高是每次检修后都出现还是就这一次?尾气洗涤塔物料参数有没有变化?没有详细的工况描述,不好分析。

尾气量与洗涤水量不匹配,或者塔内件故障
