Membrane Gas Separation Applications for CO2 EOR Natural Gas Processing Plant

Atsushi Morisato

Abstract

As the installation of the first membrane CO2 removal system for CO2 EOR plant in the early 1980s, membrane gas separation process has become a proven technology for natural gas purification, such as the removal of carbon dioxide, hydrogen sulfide, heavy hydrocarbons or nitrogen. Membrane separation systems are able to handle the bulk removal of impurities or produce pipeline specification natural gas. Such large membrane plants, nowadays, are able to process up to 1 billion standard cubic feet of natural gas per day (BSCFD) for CO2 removal. This review paper outlines the advantages of and challenges to membrane processes for natural gas purification at CO2 enhanced oil recovery plants.
