Stabilize pressure in compressor inlet

Stabilize pressure in compressor inlet

(OP)
Hello all,

I have a compression system where my compressor suctions Argon gas from a cryogenic tank. the pressure from the tank is in the range 50-75 psig (my compressor works with 50 psig suction pressure). I want to keep constant this pressure for the compressor inlet , My boss is telling me that with a buffer tank arrangement in the inlet of the compressor I could stabilize the pressure but I think just with a Pressure control valve is enough.
Please I want your advices in this topic.
thanks in advance

RE: Stabilize pressure in compressor inlet

If there is no other reason to stabilize the pressure, then a locally controlled (i.e., outlet pressure controlled by spring tension, not a PLC) pressure regulator is the normal way to do it. If you have another reason to stabilize the pressure then you have to realize the the pressure regulator is just treating symptoms, not the underlying cause of the instability.

Thanks zdas04, your answer is very helpfull

I agree with you about only use a Pressure regulator. The instability in my process is something inevitable due the behavior of the fluid. it is changing of phase (liquid to gas) frequently in the vessel and this is the reason because the pressure is not constant.
