Flow Rate of Gas & Condensate Gas in Gas Scrubber

Flow Rate of Gas & Condensate Gas in Gas Scrubber

Flow Rate of Gas & Condensate Gas in Gas Scrubber

In a gas compressor plant, a gas mixture containing 16 different gases with known composition enters a gas scrubber. The inlet and outlet pressure and temperature is known.


1. How can we calculate the flow rate (mass or volumetric, but preferably volumetric) of the condensate or the uncondensed gas? Can someone name the method used for this calculation? Or books that have information about gas scrubber calculations, or any related stuff?

2. Also since my case happens in a natural gas compressor plant which mainly produces condensate gas, how significant is the flow rate reduction for the gas lines? If there is very little reduction in gas flow, I might just assume no condensate is formed... because I need the uncondensed gas flow rate for control valve sizing.

Thank you!

You're new here so I'll cut you some slack but this is close to a double post. You should provide a link to the other post on this subject so that people don't give duplicate replies.

It depends on the gas and the amount of cooling as to what is left. Compressors normally need to use single phase gas so unless you're going from say 80 C down to minus 40 then the gas volume flow out will typically be within 10% of what goes into your condensir.

Some hard numbers (pressure, temp, flow, gas MW) would go a long way to getting some better answers.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

White Paper - Considerations for choosing a 3D printing technology
The adoption of 3D printing into major companies’ product development life cycles is a testament to the technology’s incredible benefits to consumers, designers, engineers and manufacturers. While traditional production methods have limitations in manufacturability, 3D printing provides unparalleled design freedom due to the additive method of building parts layer by layer. Download Now
