Simulation-based Design of Plate-fin Heat Exchangers for Cryogenic CO₂ Removal from Biogas
J. Environ. Nanotechnol., Volume 14, No 2 (June 2025) pp. 1-8
Abstract
Carbon Capture, Utilization, and Storage (CCUS) is essential for mitigating carbon dioxide (CO₂) emissions from major emission sources, with CO₂ removal being a fundamental step. In biomethane upgrading, the effective removal of CO₂ from biogas is essential to meet pipeline-quality requirements and improve its energy content. Among the available removal techniques, cryogenic CO₂ removal has gained considerable interest because of its ability to selectively and efficiently separate CO₂ at low temperatures. Plate-fin Heat Exchangers (PFHEs), recognized for their high heat-transfer efficiency and compact configuration, are particularly suitable for cryogenic applications. This study presents the design of a PFHE for cryogenic CO₂ removal during biomethane upgrading using Aspen EDR software. This study investigates the effect of CO₂ concentration on heat-exchanger design and heat-transfer rate.
