When a compressor system trips or shuts down generally a differential pressure drop develops. which equalizes out, if there is no depressurization (venting) takes place in the system, and arrives at a settle-out pressure. As per API 521, the minimum design pressure of the separator drum/ scrubber should be calculated as 1.05 times the settle-out pressure. This will provide an adequate differential between the operating pressure and set pressure of the pressure relief device for a compressor shutdown contingency.
