Stage separation of gas-condensate is a process in which hydrocarbon mixtures are separated into vapor and liquid phases by flashing to low pressure in several steps. Main purposes of stage separation are:
- To obtain a more stable stock-tank liquid
- To increase liquid recovery
Figure below shows typical stage separation process.
I want to share to you some terminology that I also just knew about stage separation. A two-stage separation requires one separator and one storage tank, and a three-stage separation requires two separators and one storage tank. I never thought before that the storage tank is always counted as final stage of vapor-liquid separation. Read More
