OFFSHORE ACID GAS COMPRESSION
OFFSHORE ACID GAS COMPRESSION
(OP)
I am working on an offshore project that has a design issue with regard to waste gas handling, the waste gas having high levels of H2S, the proposal is to compress the gas to export pressure using reciprocating compressors (4 stages). There are a number of concerns particularly with regard to using reciprocating compressors offshore, vibration etc. and h2s leaks.
I would appreciate feedback of simialr experience where acid gas (H2S) compression has been done offshore, in particular using reciprocating compressors/ vendors/ facility references/ specific design issues/ etc.

RE: OFFSHORE ACID GAS COMPRESSION
Depending on sources, natural gas can contain up to 28% sour gas. What is your expected concentration? If it is 28% or less, I would expect a good data base on natural gas compressors, valves, storage vessels, etc. would be appropriate. The main problem appears to be steel corrosion from high concentrations. There is a good Corrosion engineering group on Eng-Tips that may be able to advise you further for material compatability.
