Abstract: A fossil fuel fired power plant for the generation of electrical energy comprises a water steam cycle and a plant (10) for the capture of CO2 from exhaust gases emitted by the power plant and a steam jet ejector (24) configured and arranged to receive an input steam flow from a low- or intermediate pressure extraction point in the power plant and to increase its pressure. It is further arranged to receive motive steam (25) from a further extraction point in the power plant. A steam line (27, 22) directs the steam of increased pressure from the steam jet ejector (24) to the CO2 capture plant (10). The power plant according to this invention allows the use of low-pressure steam for the operation of the CO2 capture plant, where the extraction of such steam affects the overall efficiency of the power plant to a lesser degree than in power plant of the state of the art.

Abstract: A system for treating an effluent stream including a carbon capture system utilizing an amine-containing solution to remove carbon dioxide from a flue gas stream, the carbon capture system generating an effluent stream comprising degradation products generated by the amine-containing solution; storage means for storing at least a portion of the effluent stream, the storage means being fluidly coupled to the carbon capture system. The system also including at least one nozzle connected to a combustion zone of a boiler, the at least one nozzle being fluidly coupled to the storage means for providing at least a portion of the effluent stream present in the storage means to the combustion zone of the boiler through the at least one nozzle, wherein the effluent stream provided to the combustion zone is co-incinerated with a fuel in the combustion zone.

Abstract: Disclosed herein is a system comprising an absorber; the absorber permitting contact between a flue gas stream that comprises carbon dioxide and a solvent to produce a carbon dioxide rich solvent; a regenerator disposed downstream of the absorber; the regenerator being operative to dissociate the carbon dioxide from the solvent; and a compression system disposed downstream of the regenerator comprising a plurality of compression stages; where each compression stage comprises a compressor that is operative to pressurize the carbon dioxide that is dissociated from the solvent; and where at least some of the compression stages comprise a knockout tank disposed upstream of the compressor and an intercooling heat exchanger disposed downstream of the compressor; where the knockout tank is operative to remove liquid present in the carbon dioxide and where the intercooling heat exchanger is operative to remove heat generated during the pressurizing of the carbon.

Abstract: The present disclosure relates to a method of milling a fuel for an oxy-fuel combustion burner, the method includes: separating air into a hot nitrogen gas stream, having a temperature of at least 150° C. and a purity of at least 98 mol-% nitrogen, and an oxygen gas stream; leading at least a part of the nitrogen gas stream to a fuel mill; milling the fuel by means of the fuel mill in a nitrogen rich atmosphere formed by means of the nitrogen gas stream; leading the at least a part of the nitrogen gas stream away from the milled fuel; leading the oxygen gas stream to the oxy-fuel combustion burner; conveying the milled fuel to the oxy-fuel combustion burner; and burning the fuel, by means of the oxy-fuel combustion burner, in an oxygen rich atmosphere formed by means of the oxygen gas stream. The present disclosure further relates to a system for milling a fuel for an oxy-fuel combustion burner as well as to a power plant comprising such a system.
