SWCRI’s Pressure Swing Adsorption Technologies Receive Another International Patent Grant 2025-08-14 18:47:00 Recently, two pressure swing adsorption technologies independently developed by Southwest Chemical Research and Design Institute Co., Ltd. (hereinafter referred to as “SWCRI”) have successfully obtained foreign patent grants. To date, the pressure swing adsorption technology developed by Southwest Institute has received three international patent approvals, demonstrating its technical competitiveness and capability in managing intellectual property rights in the global market. The two patents granted this time are “Pressure Swing Adsorption Gas Separation System and Method (Patent Number: RU2842199)” and “High and Low Pressure Coupled Pressure Swing Adsorption Hydrogen Extraction System and Method (Patent Number: RU2842459)”. These two technologies aim primarily to reduce the energy consumption and investment required in the separation process, and they exhibit significant innovation and practicality. Core technologies protected by international patents will significantly enhance the attractiveness and bargaining power of the Southwest Research Institute’s pressure swing adsorption technologies and solutions in the international market, helping to secure major projects in broader overseas markets.
