Dear All,

Can you give me some references or information that in which industries, in which they use reciprocating compressors, there is a higher possibility of liquid formation and carryover?
I would like to know if its probability is higher in process industry, CO2 industry,...?

Regards,
Pejman

Pejman:

There is nothing unusual or negative about the existence or formation of condensed liquids in gases that are being compressed – especially in reciprocating compressors. I have installed, operated, and modified many reciprocating compressors in my career and never had problems with compressing humid gases or gases with entrained liquids in the suction stream. It is normal and standard practice to employ vapor-liquid separators in front of each compressor compression stage in order to allow removal of any liquid droplets in the gas stream. This is true of all compressors – not only reciprocating types.

Since it is to be expected that any compressor installation must be designed to protect the machine from liquids and must have the appropriate vapor-liquid separators in front of each compressor compression stage. It is the nature of the beast.

There is no industry, in my opinion, that has more propensity to feed more liquids to compressors – and if there were, it wouldn’t make any difference because the affected compressor installation should have the properly designed vapor-liquid separators in front of each compressor compression stage.

There is no issue here that I can see.
