Pumparound 和 Side stripper 在精馏塔塔设计中的区别 我在塔的设计过程，需要建立中段回流取热，请教大家那个更好。在以后的工作中还要对中段的换热器做设计优化，求教了 [ Last edited by 小蜜蜂222 on 2010-1-16 at 11:53 ] |

参见1. http://www.eng-tips.com/viewthread.cfm?qid=249628&page=1 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 [ Last edited by zzuwangshilei on 2010-1-17 at 00:41 ] |
