Parametric testing of a pilot-scale design for a moving-bed CO2 capture system using low-temperature steam

摘要

The Kawasaki CO2 Capture (KCC) system involves a solid adsorbent method that captures CO2 in exhaust gases using low-temperature steam;; thus, it can use waste heat easily and save more energy than conventional technology. In this paper, we establish a design method for a large-scale plant using the KCC moving-bed method, and conduct parametric testing using a 5 ton/d bench scale test plant to find the characteristics of the moving-bed method. Using the relationship between the residence time of the adsorbent material and the CO2 adsorption load, we found that design specifications could be applied to a large-scale plant.
