Hello all,

I am designing a process in which there is a pump pumping liquid from a tank continuously in recycle. There are two recycle loops which will be operated during continuous operation of tank or during makeup: the makeup one being the smaller loop. I want to know if I can avoid the run off point for the pump during operation by using only a plug valve in the recycle line (no orifice or control valve).

Can this be done? How can I estimate this for my process conditions and the pump?

Dear,
Could you upload the sketch showing the operating parameters? So that we could get the clear idea as your post seems confusing and not clear at least for me.

bios16,

You are asking advices but without informing the details. Any answer will be questionable.

Your question :
"I want to know if I can avoid the run off point for the pump during operation by using only a plug valve in the recycle line (no orifice or control valve). "

One of the Answer :
Yes. You can provided that you properly engineered it, specified correct plug valve and operated in and correct manner.

Your question is too general and lacking of details. You will only get general response or no answer.
