Airrain Co., Ltd. is the only domestic company specializing in polymer gas separation membranes, established in 2001 and headquartered in Cheongju, North Chungcheong Province. Led by CEO Ha Seong-yong, the company belongs to the manufacturing of distillers, heat exchangers, and gas generators. The company focuses on the manufacturing of polymer gas separation membranes as its core business and employs approximately 130 people.

Since its founding in 2001, Airrain Co., Ltd. has envisioned developing into a future-oriented, sustainable, eco-friendly energy solution company in the gas separation membrane sector through continuous innovation. By providing technology that separates gases such as carbon dioxide, methane, nitrogen, oxygen, hydrogen, and helium with high purity using our proprietary gas separation membrane products, we are striving to become a global market leader.

Business sectors

• Carbon Capture and Utilization (CCUS): We provide solutions that capture and liquefy carbon dioxide generated in various industrial sectors, such as power plants, petrochemicals, and cement manufacturing, using membrane-based technology.
• Biogas upgrading: Biogas (a mixture of methane and carbon dioxide) generated from food waste, manure, sewage treatment facilities, etc., is purified into biomethane with a methane purity of 97% or higher through a polymer gas separation membrane, making it possible to inject it into city gas pipeline networks or use it as fuel for vehicles.
• Nitrogen and Oxygen Separation/Purification: We contribute to increased safety and production efficiency by providing nitrogen generators (OBIGGS) for the inactivation of aircraft and ship fuel tanks, as well as high-purity nitrogen and oxygen separation systems required in various industrial sites.

Products

• Polymer Gas Separation Membrane Module: A key product that utilizes polymer separation membranes composed of hollow fibers with micron-sized diameters to selectively separate or concentrate specific gases from a mixed gas.
• Gas Separation System: We provide integrated systems for various purposes, such as carbon dioxide capture, biogas upgrading, and nitrogen generation, designed to meet customer requirements based on polymer gas separation membrane modules.

Special Features

• Proprietary Gas Separation Membrane Source Technology: We possess the unique technological capability in Korea to develop, manufacture, and sell polymer compound-based hollow fiber gas separation membranes, a highly advanced technology that only a handful of companies worldwide have successfully achieved.
• Energy efficiency and compact system: It is highly energy efficient with an installation area one-sixth the size of conventional wet/dry capture methods, and offers process flexibility and easy maintenance through its compact design.
• Experience in Application and Demonstration Across Various Industries: Starting with the commercialization of separation membranes for nitrogen generation, we are expanding our business into diverse fields such as biogas upgrading and carbon dioxide capture, and have verified our performance through demonstration collaborations with major companies including Lotte Chemical and Halla Cement.
