In some applications pre-treatment is required to reduce contaminants such as non-methane organics (NMOC’s) and hydrogen sulfide (H2S). The PSA process is based on physical adsorption of gas molecules on specially selected adsorbent materials. At operating pressure the adsorbents remove contaminants such as carbon dioxide and water vapor from the biogas stream and allow upgraded methane to pass through at near operating pressure. Typical pressure loss of the bio-methane product is less than 1 bar or 15 psi. The off-gas or exhaust stream removes the contaminants as part of the continuous PSA cycle by allowing the adsorbents to regenerate under vacuum pressure (typically 0.5 bar or 7.4 psia). The process repeats continuously to provide constant production of high-quality methane gas unlike other upgrading processes which require re-compression of the product bio-methane.xebec ProviDes> International engineering and design experience for project specific requirements and codes> System feasibility and optimization studies> PSA only or full gas treatment engineering and procurement solutions> Short delivery times to meet tight project schedules> Technical training programs for integrators and operators> Product and engineering support through-out the life of the plantAbout xebec ADsorPtion inc.XEBEC ADSORPTION INC. is a developer and supplier of proprietary and conventional gas purification systems for several large international markets, including biogas production, natural gas processing, natural gas for NGV’s, oil refining and compressed air.
