Gas Processing Developments

Fine-tune refrigerated LPG loading line operations

Elevation changes affect the pressure profile and phase behavior; such conditions impact product loading

Chen, C. C., Mustang Engineers, LP

Before unloading refrigerated liquefied petroleum gas (LPG) product from a storage tank to an export ship, the loading line should be cooled from ambient to loaded-product temperatures. This action minimizes LPG evaporation during ship loading. Precooling the LPG transfer/ loading line is a common practice. The cooldown operation is accomplished by running a small stream of the refrigerated product through the loading line. The partially or totally vaporized fluid is recycled to the storage tank through a cooldown-return line. LPG transfer ships usually cannot manage large vapor volumes as generated in the loading operation. If the loading line is flat (not much elevation c
