Membrane technologies have emerged as the most favorable solution for recovering condensates from fossil or natural gas. These technologies use specialized membranes to separate the natural gas stream into various components, including condensates. The membranes are designed to be highly selective, allowing only certain components to pass through while blocking others. This process results in a high-purity condensate stream that can be used in diverse applications like petrochemical production. Membrane technologies offer several advantages over traditional methods of condensate recovery, such as lower energy consumption, reduced environmental impact, and greater efficiency. As such, they are becoming increasingly popular in the natural gas industry to improve the overall efficiency and sustainability of the production process. This chapter describes the current applications, cases, and separation mechanisms of different membranes for natural gas purification. © 2024 Elsevier Inc. All rights reserved.
