Post-Combustion CO2 Capture Using Solid Sorbents: 1 MWe Pilot Evaluation

Several different reactors utilized for gas/solids contacting were considered by ADA for the CO2 adsorption and sorbent regeneration. The reactors evaluated included: fixed beds, transport reactors, moving beds, trickle down reactors, and staged fluidized beds. Working with engineers from Shaw Energy & Chemicals (now part of Technip, a world leader in project management, engineering, and construction for the energy industry), ADA selected staged fluidized beds for adsorption and a single fluidized bed for regenerating the sorbent; this decision was mainly based on optimizing heat transfer in the system. A majority of the project funds are being provided by the DOE National Energy Technology Program (formerly referred to as the Innovations for Existing Plants Program).
