Membrane-Based Purification of Biogas: Recent Advances

Abstract

Biogas, primarily composed of methane (CH₄) and carbon dioxide (CO₂), is an important renewable energy source. However, its direct use is limited due to the presence of CO₂ and other impurities like hydrogen sulfide (H₂S) and moisture. Membrane separation technology has emerged as a promising method for biogas upgrading due to its energy efficiency, compact design, and scalability. This paper reviews recent developments in membrane materials and configurations for selective CO₂ removal and methane enrichment. Particular attention is given to polymeric, inorganic, and mixed matrix membranes, along with their performance metrics such as selectivity, permeability, and durability. The study also discusses key challenges, including membrane fouling and operational cost, and outlines future directions for enhancing the commercial viability of membrane-based biogas purification systems.
