In oilfield and refinery facilities, it is common to use compressors to increase the pressure of Stripped Gas (dry gas from which liquid hydrocarbons have been removed) for further processing. For example, the boosting and transmission of Stripped Gas at oilfield stations. Another example is the pressurized transportation of dry gas from heavy oil, diesel, and naphtha hydrogenation units. At the inlet of the dry gas compressor, a dedicated vane separator is often required to serve as the separation tank at the compressor inlet (Stripped Gas Compressor Suction KO Drum). Next, let’s take as an example the Stripped Gas Compressor Suction KO Drum required for the refinery at a certain oil field in Congo by GE Oil & Gas’ EPC services, and discuss it with you.
This project is a renovation and expansion project contracted by GE Oil & Gas from the M’Boundi oil field refinery of ENI in the Republic of Congo; it involves the dry gas compressor inlet separator in the condensate recovery unit, with the equipment tag number being 02-360-1-VN-005.
