A method for capturing COfrom a COcontaining gas (), such as en exhaust gas from a thermal power plant fired on carbonaceous fuel, or any other COcontaining industrial gas, where COis captured from the gas by causing the gas to flow counter current to a COabsorbing solvent introduced into a COabsorption section () in an absorber () so that COpresent in the gas is absorbed by the COabsorbing solvent to form a COrich solvent (), where COrich solvent is collected on the bottom of the of the absorption column and withdrawn for regeneration, and where the treated exhaust gas () is released to the atmosphere after being subjected to one or more washing step(s) (), wherein the temperature of the COabsorbing solvent () introduced into the COabsorption section has a temperature that is less than 5&#xb0; C. lower than the maximum temperature in the absorption section of the absorber, is described.

Method for mist control

A method for eliminating or substantially reducing emission of amines (amineslip) and alkaline degradation products to the atmosphere from a plant for COcapture from a flue gas, where the COis captured by counter-current flow to an absorbent in an absorption zone, the absorbent comprising an aqueous solution of one or more amine(s), to give a COlean flue gas that is released into the surroundings, and a COrich absorbent that is regenerated in a regeneration column to give a COrich gas that is treated further, and regenerated absorbent that is recycled to the absorption zone, wherein the COlean flue gas is washed with an acidic aqueous solution to remove or substantially reduce the amount of amine(s) and alkaline degradation products thereof in the gas, is described.

Method and plant for amine emission control

A method for reclaiming CO2 absorbing chemical(s) from a lean aqueous CO2 absorbent leaving a regeneration column (), where lean absorbent () is withdrawn and flashed () to generate a vapor that is compressed () and returned into the regeneration column as stripper gas (), where a part of the lean absorbent () is withdrawn and introduced into a reclaimer () in which the lean absorbent is boiled to generate a gas phase () that is withdrawn and returned into the regeneration column as reclaimed absorbent, and a liquid phase containing impurities (), wherein the gaseous phase that is withdrawn from the reclaimer is compressed () together with the vapor part () from the flashing of the lean absorbent, to generate a pressure in the reclaimer that is lower than the pressure in the regeneration column, and a reboiler () for carrying out the method, are described.

A system and process is provided primarily for use in hot climates, using ammonia solution to remove carbon dioxide from desulphurised water-vapor-containing flue gases of a fossil fuel power plant, while outputting useful streams of water and fertilizer.

Carbon capture system and process

An ammonia based CO2 capture system and method is provided in which multiple absorption stages are provided. Each absorption stage delivers an ionic solution at a predetermined temperature and contacts it with a flue gas stream.

Multi-stage CO2 removal system and method for processing a flue gas stream

A method and system for COcapture from flue gas uses an absorber vessel in which a flue gas stream containing COis contacted with an ammoniated solution to remove COfrom the flue gas, and a regenerator vessel in which COis released from the ammoniated solution. Parasitic energy consumption of the system can be reduced by adding to the ammoniated solution a promoter effective to enhance the formation of ammonium bicarbonate within the ammoniated solution. The amount of ammoniated solution recycled from the regenerator vessel to the absorber vessel is less than that which would be required using the ammoniated solution without the promoter for removal of the same amount of COfrom the flue gas.

A chilled ammonia based COcapture system and method is provided. A promoter is used to help accelerate certain capture reactions that occur substantially coincident to and/or as a result of contacting a chilled ammonia based ionic solution with a gas stream that contains CO.
