Abstract
Removing acidic CO2 and H2S from natural gas, known as natural gas sweetening, is required for gas to meet sales specifications. Membrane separation technology is known to have excellent potential compared to traditional amine absorption processes. Precise and reliable mathematical models play a significant part in the membrane design system. The models relied on mass transfer, the impact of pressure gradient as a driving force, and carbon dioxide's mass transfer and chemical reaction with the solvent in the gas-liquid membrane. Mathematical model predictions revealed that increasing the pressure gradient and membrane selectivity enhances the separation efficiency. Solvent flow rate and concentration enhance acid gas removal in the hollow fiber membrane contactor. Moreover, the operation's countercurrent mode is more suitable for achieving the highest separation efficiency.
