A gas processing facility encompasses the equipment between the gas wells and the pipeline or other transportation method. The purpose of the gas facility is to remove impurities and contaminants from the gas, remove liquids and solids, and prepare the gas to meet the sales requirements of the purchaser.
The main function of a facility is to –
Separate the oil, gas, water, and solids
Deliver it to the transportation system (i.e., the pipeline, truck, ship, or railroad car)
Gas treating may involve only separation from the liquids, or it may include additional processes such as:
Compression
Dehydration
Removing H2S and CO2
Gas processing to condense heavier components that can be transported as a liquid.
Then the facility has filtration, deionization and pumping facilities.
