HIGH-PRESSURE SEPARATION OF A MULTI-COMPONENTS GAS

摘要

THE INVENTION RELATES TO A METHOD OF SEPERATING ONE OR MORE COMPONENTS FROM A MULTI-COMPONENT GAS STREAM COMPRISING AT LEAST ONE NON-ACID GAS COMPONENT AND AT LEAST ONE ACID GAS COMPONENT. A MULTI-COMPONENT GAS STREAM AT A PRESSURE ABOVE 1,2000 PSIA (82.8) AND A TEMPERATURE ABOVE 120°F (48.9°C) WITH THE CONCENTRATION OF AT LEAST ONE ACID GAS COMPONENT IN THE STREAM BEING AT LEAST 20 MOLE PERCENT IS PASSED TO A MEMBRANE SYSTEM THAT SELECTIVELY SEPARATES AT LAST ONE ACID GAS COMPONENT FROM THE MULTI-COMPONENT GAS STREAM AS A PERMEATE STREAM. THE PERMEATE STREAM HAS A PRESSURE OF AT LEAST 20% OF THE PRESSURE OF THE FEED PRESSURE.(FIG 1)
