A system for capturing carbon dioxide COby 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 MeCOto the CFB carbonation reactor.

High solids flux circulating carbonation reactor

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

Method for capturing carbon dioxide

A system for reducing carbon dioxide emissions from a flue gas generated via combusting a fossil fuel is provided. The system includes a calcination chamber and a sealing-purger. The calcination chamber is configured to receive a plurality of loaded sorbent particles and a plurality of heat-transferring particles such that the loaded sorbent particles are heated within the calcination chamber so as to release carbon dioxide. The sealing-purger includes at least one gravity driven moving particle bed. The at least one gravity driven moving particle bed allows the plurality of heat-transferring particles or the plurality of sorbent particles to enter or leave the calcination chamber while restricting the flue gas from entering the calcination chamber and the released carbon dioxide particles from leaving the calcination chamber.

System and method for reducing carbon dioxide emissions from a flue gas generated via combusting a fossil fuel

A system for reducing carbon dioxide emissions from a flue gas generated via combusting a fossil fuel is provided. The system includes a carbonator and a classifier. The carbonator is configured to receive the flue gas and carbon absorbing particles. The classifier is fluidly connected to the carbonator and configured to receive a mixture that includes heat-transferring particles and the carbon absorbing particles. The mixture is fluidized within the classifier via the flue gas at a velocity such that the flue gas entrains and transports the carbon absorbing particles to the carbonator while the heat-transferring particles are not entrained nor transported to the carbonator.

A carbon capture system includes a Carbonator for adsorbing carbon dioxide with a carbon dioxide lean sorbent generating a carbon dioxide rich sorbent, a first Calciner for thermally decomposing a carbon dioxide rich sorbent into a carbon dioxide lean sorbent and carbon dioxide, a supply of raw material to be calcined into the first Calciner containing a carbon dioxide rich sorbent, a connection between the first Calciner and the Carbonator, a second Calciner for thermally decomposing a carbon dioxide rich sorbent into a carbon dioxide lean sorbent and carbon dioxide, a connection between the Carbonator and the second Calciner, and a connection between the second Calciner and the Carbonator.

Carbon capture system and method for capturing carbon dioxide

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.

Method for calcination of a carbon dioxide rich sorbent

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 COloaded liquid and a wash water liquid to form a COenriched wash water liquid that is then brought into contact with the combustion flue gas.

A method for calcination of a carbon dioxide rich sorbent (containing CaCO) 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 CaCO) 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.

Calciner for calcination of a carbon dioxide rich sorbent

The present invention relates to a method for capturing carbon dioxide COby 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 MeCOto the CFB carbonation reactor. Also a system recirculating the metal oxide MeO and metal carbonate MeCOis provided by the invention.
