A Review of the Natural Gas Purification from Acid Gases by Membrane

Abstract

This study aims to shed light on natural gas as an important and promising energy source. This energy source is the fastest-growing source in the world due to the increasing global demand. In this paper, the rates of growth in global demand for natural gas according to the latest reports since 1984, as well as the gas specifications required for transport and storage, acid gases, including absorption, desorption, Cryogenic and separation by membranes, are discussed with the advantages and disadvantages of each method. Focusing are presented. In addition to the primary treatment processes that take place on the gas, the most important of which is the removal of acid gases. Processes for removing on the membrane separation process as the most promising process in this field and reviewing all the research that is discussed in details of this process.
