  • Publication number: 20230321590
    Abstract: An aqueous liquid sorbent suitable for use in separating a target gas from a mixture of gases in a rotating packed bed gas capture system, comprising a first amine compound, a second amine compound and water, wherein the sorbent comprises at least 16 wt % of the first amine compound and at least 51 wt % of total amine compounds, the first amine compound has a reaction rate with the target gas that is greater than the reaction rate of the second amine with the target gas, and the second amine compound has a solubility in water that is greater than the solubility of the first amine compound in water.

  • Publication number: 20230256382
    Abstract: Disclosed herein is a rotating packed bed, RPB, arrangement configured to provide mass transfer between a liquid sorbent and a gas, the RPB arrangement comprising: an RPB configured to provide a substantial cross-flow between a liquid sorbent and a gas; and a spray arranged to spray the liquid sorbent onto the RPB; wherein the RPB and spray are both arranged at different longitudinal positions on a gas flow path through the RPB arrangement.

  • Publication number: 20080060346
    Abstract: The present invention relates to a method for removing and recovering CO2 from exhaust gas from a gas turbine based electric power and heat generation process (a main power process) by chemical absorption and desorption for deposition of CO2 as convenient at the location. The exhaust gas from said main power process is cooled before being fed to a secondary gas turbine based power and heat generation process (a secondary power process) where said exhaust gas is compressed to elevated pressure and used as oxidant in a secondary gas turbine combustion chamber in said secondary power process. The resulting hot exhaust gas from said secondary process is further fed to a turbine connected to an electric power generator where the exhaust gas is depressurised to close to ambient pressure before entering a heat recovery process where the exhaust gas is cooled and further fed to a CO2 separation process for capturing of CO2.
