Design of Plate-Fin Heat Exchanger for CO₂ Separation by Cryogenic Distillation

Abstract Carbon capture, utilization, and storage (CCUS) is a technique to curb carbon dioxide (CO 2 ) emissions from significant point sources. CO separation the first stage in CCUS. Cryogenic emerging method of separating different Plate-fin heat exchanger (PFHE) one compact exchangers generally used cryogenic applications. Due its advantages, it also process. In this analysis, PFHE designed analyzed by using an analytical Aspen software, results are compared. design, Maiti Sarangi correlations considered. The effect change thermos-physical properties on volume cost (HX) analyzed. energy penalty separate /N gas mixture with 30% concentration observed be 1.063 MJ/kg . volumes HXs “A” “B” determined approach found around 0.323 m 3 0.978 , respectively.
