增大回流比,增加塔板数。

不知你们是什么工艺流程

前脱丙烷后加氢,lummus工艺

3.jpg我单位是DMTO装置,脱甲烷塔顶为减少乙烯损失,采用丙烷冲洗!不知道你们的丙烷流量是多少?
Reply #72018-01-18
一般是增加回流,有丙烷洗的工艺的可适当增加丙烷洗的量,我们的是有丙烷洗,可以实现,但是负荷高时不太容易掌握平衡,不好控制,主要根据塔顶温度进行控制

DMTO装置,采用丙烷洗,减少乙烯损失
Reply #92018-01-24
须综合评定乙烯损失与加大丙烷带来的能耗增大之间的关系

增大回流比,稍微提高塔顶压力

目前mto的工况,降到0.5%没什么太大问题。

一般情况下,即使脱甲烷塔塔釜的甲烷超了,乙烯精馏塔的甲烷也不会超的,这个就需要精细化控制了。至于减小再沸,最好就是通过循环水调节产品气温度比较有效。丙烷洗当然大了会好些。但会增加脱乙烷塔、丙烯塔的负荷。因此,设备定了,可能就很难降了。至于塔压的影响,理论上有,但是实际上没那么明显。

目前已调整差不多了 节约乙烯的成本还是很划算的。

脱甲烷塔要是能够将溶解过程中的热量进行同步移除,这样脱甲烷塔的效果可以更好。
