From Waste to Biomethane: Development of PSA Process for Landfill Gas Upgrading
Short Introductive summary
Landfill gas (LFG), primarily composed of methane (CH4) and carbon dioxide (CO2) with a noticeable amount of Nitrogen (N2) represents a significant renewable energy source but poses environmental challenges due to its contribution to greenhouse gas emissions. In order to obtain biomethane, all compounds other than CH4 must be separated; while CO2 removal technologies are well established, the separation of nitrogen (N2) from methane remains a technical challenge due to their similar physical properties. This study presents the development of a vacuum pressure swing adsorption (vPSA) system integrated with membrane-based CO2 removal for efficient nitrogen rejection in small-scale LFG upgrading plants. The approach involves sorbent screening,followed by detailed matherial characterization, cycle desin and simulation, experimental validation. The solution proposed by AB Group offers a modular, cost-effective alternative to benchmark systems, facilitating biomethane production from decentralized landfill sites.
