Electrochemical Membrane Technology For Carbon Dioxide Capture From Flue Gas, Hossein Ghezel-Ayagh, Stephen Jolly, Dilip Patel, William Steen

CO2 Summit II: Technologies and Opportunities

To address the concerns about climate change resulting from emission of CO₂ by power plants and industrial facilities, FuelCell Energy, Inc. (FCE) has developed the Combined Electric Power and Carbon-dioxide Separation (CEPACS) system. The CEPACS system utilizes Electrochemical Membrane (ECM) technology derived from the Company’s molten carbonate fuel cell-based Direct FuelCell^® products. The system separates CO₂ from the flue gas of other plants and produces electric power using a supplementary fuel. FCE is currently evaluating the use of ECM to cost effectively separate CO₂ from the flue gas of Pulverized Coal (PC) power plants under cooperative …

CO2 Summit II: Technologies and Opportunities

Current concerns about atmospheric carbon levels have sparked demands for massively reduced carbon emissions. These demands, both environmental and regulatory, exceed the capacity for near-term deployment of emission free technologies. Therefore, to simultaneously meet carbon emission targets and supply the vast global energy demands in the foreseeable future, energy generation must incorporate carbon-capture and sequestration technologies on point source CO­₂ emitters such as coal-fired power plants.

Coal-fired power plants have long been the primary energy pillar of industrialized nations, and while reduced utilization is an important target for CO₂ reduction, coal combustion remains the most intensive and prevalent …

Integration Of High-Fidelity Co2 Sorbent Models At The Process Scale Using Dynamic Discrepancy, Joel Kress, Kujin Li, David Mebane, Priyadarshi Mahapatra, Sham Bhat

CO2 Summit II: Technologies and Opportunities

A high-fidelity model of a mesoporous silica supported, polyethylenimine (PEI)-impregnated solid sorbent for CO₂ capture has been incorporated into a model of a bubbling fluidized bed adsorber using Dynamic Discrepancy Reduced Modeling (DDRM). The sorbent model includes a detailed treatment of transport and amine-CO₂-H₂O interactions based on quantum chemistry calculations. Using a Bayesian approach, we calibrate the sorbent model to Thermogravimetric (TGA) data. Discrepancy functions are included within the diffusion coefficients for diffusive species within the PEI bulk, enabling a 20-fold reduction in model order. Additional discrepancy functions account for non-ideal behavior in the adsorption …

Novel Advanced Solvent-Based Carbon Capture Pilot Demonstration, Nathan Brown, Greg Staab, Tyler Silverman, Grayson Heller, Alfred Brown

CO2 Summit II: Technologies and Opportunities

ION Engineering’s advanced solvent is one of the leading second generation solvent systems currently under development for post-combustion carbon dioxide (CO₂) capture. Throughout small scale pilot testing with coal and natural gas fired flue gas, bench scale pilot and laboratory testing, ION’s advanced solvent has consistently demonstrated 30+% reductions in regeneration energy requirements in comparison to traditional aqueous monoethanolamine (Aq-MEA). These results, in addition to CO₂ solvent carrying capacities 35% higher than Aq-MEA and significantly less solvent degradation, demonstrate that ION’s CO₂ capture technology has the potential to significantly reduce both capital and operating costs.
