Dynamic Design Simulation of Acidic Natural Gas Sweetening Analysis and the Utilization of Hybrid Amine Membrane

In order to remove acid gases, chemical absorption by solvents is the most often used sweetening gas strategy. While this method is well-known and tested, it may be difficult to implement, expensive, and wasteful when used to extract very acidic gas. But novel polymeric membranes have been used to remove large amounts of H2S from natural gas, even at high levels of H2S. Recent advancements in this field might lead to the production of unconventionally high acidity gas or the retrofitting of existing facilities. For example, the membrane system might be used to lower the bulk concentration of H2S and CO2 in the input gas. An amine-based method might be used to sequentially meet the ultimate sweet gas product criteria. It is thus possible to reduce capital and operational costs by using this sort of hybrid design. Using a simulation-based approach, this research evaluates the sweetening of extremely acidic gas with 15% H2S (i.e., over 20% of H2S and CO2 combined). ProMax® v3.2 was used to model the suggested hybrid procedure. According to the simulation findings, a hybrid system approach to the sweetening process might cut operational and utility costs (instead of a stand-alone amine system).
