Description
Carbon dioxide capture has been limited in its commercialization due to both capital and operating costs of the as-developed technologies. In this proposal, a hybrid, intensified process approach will be used to lower the overall cost of capture operations, enabling further commercialization of the process. The hybrid technology proposed here will use (1) 3-D printed two-channel structured packing to be installed at the top 1/3 section of the absorber packing with one channel for gas-solvent reaction and another for coolant for in-situ heat rejection to control the temperature profile for improved CO2 capture mass transfer; (2) a zeolite membrane-based dewatering unit to decouple the solvent concentration for absorption and desorption; and (3) a secondary heat transfer unit between the lean and rich solvents prior to the stripper providing a secondary point of rich solvent injection into the stripper which will allow for multiple points of vapor generation due to additional decoupling of the carrier gas requirement and heat provider requirement for stripper operation, which will allow the solvent regeneration process to be performed at lower temperature, utilizing lower pressure steam (~1 bar vs 5 bar for Ref Case 12), and resulting in greater power generation from the steam turbine.
