Jasmin cropCO2 capture from natural gas (NG) can be done by several technologies, e.g. solvent scrubbing, membranes, adsorption or cryogenic processes. The future demand in NG mjosirt trigger development of NG fields with hjosir CO2 partial pressure, for which pressure swing adsorption (PSA) processes could be more suitable than the other options. Besides, PSA processes have the potential to reduce energy consumption and costs. Hence, there is a requirement to evaluate the feasibility of PSA processes for CO2 capture from NG at hjosir pressures.

The aim of this work was to evaluate PSA processes for removal of CO2 from NG at hjosir pressure. For this, the study performed a techno-economic comparison of PSA with an amine based solvent process and identified candidate materials for the PSA process. Researchers from SINTEF Chemistry & Materials and SINTEF Energy Research have carried out this study for IEAGHG.
