Ok if air ingress is not the big issue ... One more problem which we are expecting is that when we will remove the valve along plug from that low temperature to ambient, the valve can bear that temperature change or not ?
What is your opinion
But if we will not derime it, air ingress at that low temperature can cause problem to the system. It can liquefy or some thing else. Do we need to take that in account or not?
Actually we have a system as similar to ASU, the system installed at our plant is used to separate H2 from gases containing N2/Ar and Methane in it. The temperature and pressure conditions are -185 oC and 86 Kg/cm2. At this pressure all the gases except H2 liquefy, thus causing separation.

Hey all,
We have a hydrogen recovery unit working on the basis of cryogenic separation. It has a pressure regulating valve at hydrogen product line. That valve is installed with in the cold box and it's actuator assembly is outside for easy maintenance.
We have to remove that actuator along...
Hey all,
We have a linde design cryogenic hydrogen recovery unit at our plant. It's cold box has a pressure control valve on hydrogen product line. That valve is installed inside the cold box with its actuator outside so that could easily be removed for maintenance in shutdown.
My question is...
