ABSTRACT
Mallet (1988) provides an excellent description of the San Juan gas plant located in New Mexico. Figure 15.1 shows a block schematic of the plant, which is capable of processing 500 MMscfd (14 MMSm
/d) of low-sulfur gas, with the emphasis on obtaining extremely high ethane recovery. To accommodate limitations on equipment sizes and to minimize the loss of productivity during equipment downtime, gas is produced in two identical 250 MMscfd (7.1 MMSm
/d) streams. The streams split after the heat exchange section. Like many modern gas plants, it generates its own power by use of gas turbines and relies heavily upon centrifugal compressors.
