Abstract: A method for integrating a carbon capture process with a process for cement production.

Abstract: A system for capturing carbon dioxide CO2 by carbonation in a circulating fluidized bed (CFB) carbonation reactor wherein temperature profile is adjusted by recirculation of solid fractions of metal oxide MeO and metal carbonate MeCO3 to the CFB carbonation reactor.

Abstract: A method for calcination includes providing a heated coarse solid particle stream with a carbon dioxide rich sorbent to a reactor having a rotatable container.

Abstract: A method for capturing ammonia present in combustion flue gas subjected to carbon dioxide removal using a water wash unit included in a chilled ammonia process. The method includes combining a CO2 loaded liquid and a wash water liquid to form a CO2 enriched wash water liquid that is then brought into contact with the combustion flue gas.

Abstract: A method for calcination of a carbon dioxide rich sorbent (containing CaCO3) includes combusting in a furnace a fuel with an oxidizer, supplying heat transfer (HT) solids into the furnace and heating them, transferring the HT solid particles from the furnace to a reactor having a rotatable container, supplying a carbon dioxide rich solid sorbent (containing CaCO3) into the rotatable container, rotating the rotatable container for mixing the solid particles and the carbon dioxide rich solid sorbent for transferring heat from the solid particles to the carbon dioxide rich solid sorbent and generating carbon dioxide and carbon dioxide lean solid sorbent (mainly CaO), discharging the carbon dioxide and the carbon dioxide lean solid sorbent from the rotatable container and the subsequent classification of the HT solids from the lean sorbent.

Abstract: The arrangement of a flue gas treatment system by carbonation-calcination loop and soda ash production system by Solvay process has CaO and heat for use in the soda ash production system extracted from the flue gas treatment system.

Abstract: The present invention relates to a method for capturing carbon dioxide CO2 by carbonation in a circulating fluidized bed (CFB) carbonation reactor wherein temperature profile is adjusted by recirculation of solid fractions of metal oxide MeO and metal carbonate MeCO3 to the CFB carbonation reactor. Also a system recirculating the metal oxide MeO and metal carbonate MeCO3 is provided by the invention.

Abstract: The present invention relates to a method and system for cleaning a process gas containing carbon dioxide and contaminants, by bringing the process gas into direct contact with an alkaline solution or slurry, and capturing in the alkaline solution or slurry at least a part of the contaminants of the process gas; and bringing the process gas, depleted in contaminants, into direct contact with a cooling liquid to form a cooled process gas; wherein said alkaline solution or slurry is separate from the cooling liquid.

Abstract: The system includes a first reactor configured to discharge CO2 depleted process gas. The first reactor having a first and a second portion of particulate sorbent material having captured CO2. A second reactor is arranged to receive the first portion of particulate sorbent material and is configured to release CO2 from the particulate sorbent material by decarbonation, return the first portion of particulate sorbent material to the first reactor, and discharge a CO2 rich gas stream. A third reactor is arranged to receive the second portion of particulate sorbent material and is configured to supply water to the second portion of particulate sorbent material to hydrate at least a part of a remaining portion of calcium oxide of the second portion of particulate sorbent material to form calcium hydroxide, and return the second portion of particulate sorbent material to the first reactor.
