ABSTRACT
Pressure plays a major role in gas processing, as it moves gas from the field, through the gas plant, and into the sales gas line. Pressure provides the source for cooling the gas to low temperatures. Process streams that undergo compression include the following:
• Gas leaving inlet receiving (Chapter 3). To maximize liquids recovery, the gas must be at 850 to 1,000 psi (60 to 70 bar) when it enters the hydrocarbon recovery section but at 600 to 650 psi if only primarily propane and heavier components are recovered (see Chapter 7).
