Hello,
I saw in one of our P&ID that there is a Restricted Orifice (RO) after the cylnder of the reciprocating compressor (used for pressurizing the natural gas). As a beginner, I m confused about the usage of the RO. We use the compressor to increase the pressure of the natural gas but RO is intended to cause permanent pressure loss? What could be the reason to use RO there?
Sorry for not sharing all the process. After the RO, natural gas leads to the cooler.
I would be grateful if you could answer my question.
Thank you in advance.
