“…In recent years, various materials such as iron-oxidebased materials (Feng et al, 2020), zeolites (Rahmani et al, 2023), polymeric membranes (Casadei et al, 2020), and activated carbon (de Oliveira et al, 2020) have been used to remove sulfurous compounds through adsorption. Hydrogen sulfide (H 2 S) is a colorless, extremely dangerous, corrosive, flammable gas heavier than air.…”

“…However, due to the geological conditions in which natural gas deposits are formed, acid gases are also extracted along with hydrocarbons. In addition to reducing the energy efficiency of fuel, acid gases also create additional risks [8][9][10][11]. First of all, they are associated with corrosion of gas transmission equipment.…”

The present study focuses on the development and optimization of a highly efficient unique hybrid technique — membrane-assisted gas absorption (MAGA) in designing the separation unit, which provides the improvement in mass-transfer of a target component during the natural gas processing in terms of sweetening stage. A novel design of membrane-assisted gas absorption cell is used to enhance the ratio between absorbent amount and membrane surface available for permeation. The performance tests were implemented on example of two gas mixtures separation: one is model ternary gas mixture and the second is quasi real natural gas, which includes number of hydrocarbons, nitrogen, acid impurities and xenon. For both cases, the MAGA unit demonstrated high acid gases removal efficiency, and high recovery of hydrocarbons. The ultimate efficiency of studied system was up to 96 and 61 % of removed acid gases with hydrocarbons losses up to 1 % at highest productivity. In this way, the residual sum of acid gases content may be lowered to 1 vol.% using the heat-free hybrid membrane-assisted gas absorption unit maintaining suitable recovery rate of methane, ethane, propane and n-butane. Nevertheless, the overall efficiency of the process may be enhanced using the specific absorption agents with aqueous amino alcohol solutions.
