Pressure Swing Adsorption (PSA) Technology


Pressure Swing Adsorption (PSA) is based on the concept that different components have a different absorption potential than others. In this case, CO2 is adsorbed in the PSA columns that are filled with molecular sieve media, while CH4 is concentrated to produce RNG.

The PSA process used in the system is a physical process widely applied in the gas industry to purify different gas streams for a variety of industrial applications and can be explained in two simple process steps: Adsorption and Desorption. The system automatically synchronizes adsorption/desorption of different vessels to allow for the production of a steady and continuous biomethane quality, even at varying inlet gas quality or volume flow. Unlike other upgrading systems and due to a special guard bed, the STATERON PSA system is less sensitive to the performance of the activated carbon filters.
