Hi All, I am new here. But have a question.
I am looking for a way to size pressure relief valves for thermal relief or fire relief. The application is a suction scrubber on a gas compressor. Normally, I size all my relief valves to relief full flow of the compressor. This is leading to us having some really big valves on the compressor skid, and that leads to more money and bigger pipe, and clearance issues, ETC ETC.
So I am looking for some credible source of reference to size a relief valve for thermal expansion/fire. I am seeing sizing in some places, sizing for this is based on how much gas you have contained in the area you are protecting. That said, you would need to be able to relieve that pressure, i.e. protecting your suction scrubber and piping. Well, what rate does that pressure/volume need to be released at? What criterion exists?
Just need some threads to grab at to see where I can go with this.
