Abstract
Oil and gas production and their separation processes result in the emission of greenhouse gases (GHG) such as methane and carbon dioxide. In order to reduce the emission volume, membrane–based separation technologies deserve special attention. After reviewing the gas separation method in oil and gas section, we will discuss the roles of the CVD–based inorganic membranes. Thermally–stable, organic solvent resistant, and robust nano–filtration membranes are also strongly required for the purification of produced water. We also introduce the progress of the development of diamond–like carbon membranes, as well as some oil adsorbents for the separation and recovery of oil in produced water.
