Re: Discharge pressure of ammonia compressor
Maximum discharge pressure if system is designed correctly is 10-15% below lowest relief valve setting on high side of plant.
Relief valve should have been selected by looking at maximum design pressure on each pressure vessel or component.
Have a look at reliefs on compressor, high pressure liquid receiver & whatever in on high side.
What ever is lowest setting based on that you high pressure switch should be minimum 10% below that.
