Top 10 Companies in the Gas Separation Hollow Fiber Membrane CO2 CH4 N2 Polysulfone Market (2026): Market Leaders Powering Global Energy Transition

MARKET INSIGHTS

Global gas separation hollow fiber membrane (CO2, CH4, N2) polysulfone market size was valued at USD 1.54 billion in 2025. The market is projected to grow from USD 1.67 billion in 2026 to USD 3.12 billion by 2034, exhibiting a CAGR of 7.9% during the forecast period.

Gas separation hollow fiber membranes made from polysulfone are advanced polymer‑based filtration structures engineered to selectively separate gases such as carbon dioxide (CO2), methane (CH4), and nitrogen (N2) from mixed gas streams. These membranes operate on the principle of solution‑diffusion, leveraging the differential permeability of gases through the dense polysulfone polymer matrix. Their hollow fiber geometry maximizes surface‑area‑to‑volume ratio, making them highly efficient for industrial‑scale applications including natural gas sweetening, biogas upgrading, nitrogen generation, and enhanced oil recovery.

The market is witnessing robust growth driven by rising demand for natural gas purification, increasingly stringent environmental regulations targeting CO2 emissions, and the global push toward cleaner energy sources. Furthermore, the expanding biogas sector and growing adoption of membrane‑based separation over conventional cryogenic and absorption technologies – owing to lower energy consumption and reduced operational costs – are accelerating market expansion. Key players operating in this space include Air Products and Chemicals, Inc., Evonik Industries AG, Air Liquide S.A., and UBE Industries, Ltd., each maintaining strong portfolios of polysulfone‑based hollow fiber membrane solutions.
