Abstract: The invention refers to method for electrochemical reduction of CO2 in an electrochemical cell having a cathode and an anode. The method comprises: at the cathode, reducing the CO2; at the anode, oxidizing a first hydrocarbon generating a second hydrocarbon.

Abstract: Systems and process for volatile degradation removal from amine plant wash water are provided. The systems and processes include a separation device disposed within a water circulation loop and configured to continuously remove at least a portion of the volatile degradation products from the wash solutions. The separation device can be configured for stripping, distillation, and/or extraction of the volatile degradation products from at least a fraction of the spent wash water. Optionally, a chemical agent can be reacted with the volatile degradation products to form heat stable salts for subsequent removal.

Abstract: A carbon dioxide capture system includes a solid sorbent material including an amine. A base solution is in communication with the sorbent material when the amine becomes deactivated. The base solution is removed from the sorbent material when the amine is regenerated by the base solution.

Abstract: A flue gas treatment system includes a CO2 absorber having an inlet for receiving a SO3 aerosol containing gas in the CO2 absorber. An amine solvent is supplied to the CO2 absorber. The CO2 absorber has a high temperature region and a lower temperature region. The high temperature region is configured to create an amine vapor and the lower temperature region is configured to cause the amine vapor to condense on the SO3 aerosol creating SO3/amine droplets. A SO3 aerosol removal device is positioned downstream of the CO2 absorber for removing the SO3/amine droplets from the gas.

Abstract: A system and method for removing carbon dioxide from a gas stream. One aspect of the method includes introducing a carbon dioxide containing gas stream to an absorber; contacting the gas stream with an amine-containing solvent; absorbing, with the amine-containing solvent, the carbon dioxide from the gas stream, thereby removing the carbon dioxide from the gas stream; and forming a precipitate with the amine-containing solvent and the carbon dioxide.
