  Abstract

To develop SEWGS (sorption enhanced water gas shift) system using dry CO2 absorbent for pre-combustion CO2 capture, hydrodynamic characteristics of CO2 absorbents were measured and investigated. The minimum fluidization velocity of CO2 absorbent was measured and the effects of the operating conditions were investigated to operate the system at bubbling fluidized bed condition. The minimum fluidization velocity decreased as pressure and temperature increased. Moreover, the minimum fluidization velocity decreased as column diameter increased. The effects of operating conditions on the solid circulation rate were measured and investigated to select appropriate operating conditions for continuous CO2 capture and regeneration. The measured solid circulation rates were ranged between 10 and 65 kg/hr and increased as the solid injection velocity, gas velocity in the regeneration reactor, and solid height increased.
