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to form a COrich solvent (), where COrich solvent is collected on the bottom of the of the absorption column and withdrawn for regeneration, and where the treated exhaust gas () is released to the atmosphere after being subjected to one or more washing step(s) (), wherein the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absorbing chemical(s) from a lean aqueous CO2 absorbent leaving a regeneration column (), where lean absorbent () is withdrawn and flashed () to generate a vapor that is compressed () and returned into the regeneration column as stripper gas (), where a part of the lean absorbent () is withdrawn and introduced into a reclaimer () in which the lean absorbent is boiled to generate a gas phase () that is withdrawn and returned into the regeneration column as reclaimed absorbent, and a liquid phase containing impurities (), wherein the gaseous phase that is withdrawn from the reclaimer is compressed () together with the vapor part () from the flashing of the lean absorbent, to generate a pressure in the reclaimer that is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.

[object Object]

A method and a plant for capturing COfrom an exhaust gas from combustion of carbonaceous material are described. At least a part of the combustion gas is introduced into a biol fuel boiler as an oxygen containing gas, to increase the concentration of COand decrease the oxygen concentration in the gas before introduction into an absorption column for separation of CO.

A method for removing COin a exhaust gas from combustion of carbonaceous material, in which method the exhaust gas is brought in countercurrent flow with a liquid COabsorbent in a contact section of an absorption column, to produce a COdepleted exhaust gas that is released into the atmosphere and a COrich absorbent that is withdrawn from the absorption column, wherein the exhaust gas is introduced into the absorption column at a temperature above about 90 and the exhaust gas is cooled in the absorption column by countercurrent flow of the liquid absorbent in the absorption column, is described.
