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 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 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.

The present invention relates to a method and a system for cleaning a COrich flue gas stream containing water vapor and NOprior to COsequestration. The method and system include heating the flue gas stream to a temperature suitable for selective catalytic reduction (SCR) of NOin a flue gas heater, reducing at least some of the NOin the heated flue gas stream to Nby SCR, and removing at least some of the water vapor from the NOdepleted flue gas stream by adsorption in an adsorption drier.

A method for combustion of a fuel and treatment of the resulting flue gas includes: combusting a fuel to produce a hot flue gas stream containing at least carbon dioxide (CO) and sulfur dioxide (SO), bringing the flue gas stream into contact with solid calcium oxide (CaO) in a carbonation reactor operating at a temperature at which COin the flue gas reacts with CaO to form solid calcium carbonate (CaCO), heating CaCOin a calcination reactor operating at a temperature at which CaCOis converted to CaO and CO, and recirculating CaO formed in the calcination reactor back to the carbonation reactor. Heating can be at least partially effected by indirect heat exchange with hot flue gas from the combustion. Flue gas used for the indirect heat exchange can be subsequently subjected to dry desulfurization before it is brought into contact with CaO in the carbonation reactor.

Desulfurization in a regenerative calcium cycle system

A water-coolable grate plate including a top surface, oppositely disposed sides and at least one cooling channel which is thermally connected to the top surface. The cooling channel connects a first coolant port, which is substantially centered between the sides of the grate plate, to a second coolant port, which is positioned at a distance from the first coolant port.
