Pressure swing adsorption (PSA) is quickly becoming one of the more favorable processes for capturing CO2 from flue gas because of its favorable economics and ease of implementation. This presentation will introduce the fundamentals of a PSA process, compare it to amine scrubbing and then show how sensitive the performance of a PSA process is to slight changes in a PSA cycle schedule. It will also show that a PSA process can be easily designed to capture CO2 from flue gas with greater than 95% purity and 90% recovery, even in the presence of water vapor. This presentation will discuss the effect of various parameters like the total cycle time, feed temperature, pressure ratio, feed concentration, and purge to feed ratio on the overall process performance. Finally, this presentation will highlight the power requirements and the cost of capturing and sequestering CO2 by PSA.
