A Process with Decoupled Absorber Kinetics and Solvent Regeneration Through Membrane Dewatering and In-Column Heat Transfer

The University of Kentucky Center for Applied Energy Research (UK CAER) has teamed with Media and Process Technology Inc. and Lawrence Livermore National Laboratory (LLNL) through support project FWP-FEW0242 to develop an intensified, innovative carbon dioxide (CO2) capture process. The project goals are to increase system efficiency and enable significant reductions in capital and operating costs of solvent-based post-combustion capture through: (1) the use of 3D-printed, two-channel structured packing material to control absorber temperature profile and increase the CO2 absorption rate, thereby allowing decreases in absorber size; (2) implementation of a zeolite membrane dewatering unit capable of substantial dewatering of carbon-rich solvent to decouple solvent concentrations that are optimum for CO2 absorption and desorption; and (3) utilization of a two-phase flow heat exchanger prior to the stripper, providing a secondary point of vapor generation for CO2 stripping resulting in significant energy savings.
