Abstract

CO₂ capture from large stationary sources is considered as one of the most promising technologies to mitigate CO₂ emissions in atmosphere and reduce global warming. Amine absorption is the state-of-the-art technology for CO₂ capture, while high energy consumption and potential environmental impacts due to solvent emission and degradation needs to develop second generation solvents with high CO₂ loading capacity. Seeking environmentally friendly and energy efficient process with gas separation membranes could be an alternative for this application. In order to compare process feasibility of different techniques for CO₂ capture, the general criteria on energy consumption and cost estimation were provided in the current work. The proposed criteria provided an effective way in techno-economic feasibility analysis for CO₂ capture by easily adjusting relevant parameters. HYSYS simulation was conducted on a scenario of CO₂ capture from a gross output 819 MWe power plant with novel fixed-sitecarrier membranes. A relatively low efficiency penalty of 10% and a competitive CO₂ capture cost of 47.3 $/tonne CO₂ captured were found to be competitive to conventional amine absorption. Membrane systems have potentials for CO₂ capture if such performance can be achieved on pilot scale demonstration.
