Abstract

The University of Illinois at Urbana-Champaign is developing and testing a Hot Carbonate Absorption Process with Crystn.-Enabled High Pressure Stripping (Hot-CAP) to overcome the energy use disadvantage of conventional monoethanolamine-based processes. The Hot-CAP process employs a potassium carbonate aq. soln. as a solvent. The process features high pressure CO2 stripping of a soln. highly loaded with CO2, which is enabled by bicarbonate crystn. Exptl. studies are being conducted to investigate the kinetic and thermodn. performance of absorption, crystn., and stripping unit operations under the typical process conditions. This paper presents a CO2 absorption study that focuses on screening of promoters in a lab. stirred tank reactor and an evaluation of absorption performance of promoted carbonate solns. in a bench-scale packed bed column. on SciFinder(R)]
