请问side stripper是侧线的意思吗?用它可以表示中段循环回流吗?

one distillation column operates at 30 % and other is at 70 % of total capacity .Now the draw nozzle for pump around and side stripper is common .
For pump around the draw is measured and regulation by a FCV from both column and is then enetred back in the column in the same quantity they were  drawn .
2.http://encyclopedia2.thefreedictionary.com/pumparound
A system or process vessel that moves liquid out of and back into the vessel at a new location; for example, in a bubble tower, the withdrawing of liquid from a plate or tray, followed by cooling, and returning to another plate to induce condensation of vapors.
3.http://www.hgbbs.net/bbs/thread-56872-1-1.html
Pumparounds是从塔内采出物料再返回,也就是循环物流。即通过中间物料循环换热

如果只是取热的话当然用pumparoud,stripper是需要提供外部热源,将物流里面的轻组分汽提出来返回塔里,两个是不一样的...
