Summary

NGL (NATURAL GAS LIQUIDS) PLANTS EXTRACT ETHANE, PROPANE AND HEAVIER LIQUIDS THROUGH DISTILLATION. TO ACHIEVE SEPARATION BETWEEN ETHANE AND METHANE, CRYOGENIC TEMPERATURES ARE PRODUCED, PRIMARILY BY ADIABATIC EXPANSION OF INLET GAS. CONTROL IS COMPLICATED BY VARYING REQUIREMENTS IN PRODUCT SPECIFICATION DETERMINED BY CLIENT USAGE. CLOSE CONTROL OF COLUMN PRESSURE AND BOTTOM TEMPERATURE, SOMETIMES AT LEVELS LOWER THAN COMMONLY USED, CAN INCREASE ETHANE RECOVERY BY UP TO 7%. AUTOMATION, SET FOR EACH PRODUCT SPECIFICATION, CAN OPTIMISE EFFICIENCY. D.W.H.
