Abstract: A catalytic reactor (16) is provided for purposes of effecting therewith the removal of nitrogen oxides from a process gas (F) that includes at least two catalyst bed segments (48, 50, 52), each of which is provided with a closing device (60, 62, 64). The catalytic reactor (16) is operative for causing said process gas (F) to flow through a first catalyst bed segment (48). Said process gas (F) is at a first temperature at which the sulphur trioxide that is entrained in said hot process gas is at least partially precipitated out on to the catalytic material that said first catalyst bed segment (48) embodies. Periodically said closing device (60) is operated in order to thereby isolate said first bed segment (48) from the flow therethrough of said hot process gas (F). A regeneration system (34, 36, 38) is also provided that is operative for purposes of causing a regenerating gas to flow through the first bed segment (48).

Abstract: A method for removal of CO2 from a flue gas stream, comprising the steps of: a) contacting a flue gas stream comprising CO2 with a first absorption liquid comprising NH3 such that the flue gas stream is depleted in CO2; b) contacting the flue gas stream depleted in CO2 of step a) with a second absorption liquid such that NH3 from the flue gas stream is absorbed in said second absorption liquid to form a flue gas stream depleted in CO2 and NH3; c) separating NH3 from the second absorption liquid such that a gas stream comprising NH3 is obtained; d) contacting said gas stream comprising NH3 separated in step c) with a third absorption liquid such that NH3 is absorbed in said third absorption liquid. A system for removal of CO2 from a flue gas stream, the system comprising: a CO2 absorption stage; an NH3 absorption stage; and a reabsorption stage.

Abstract: A combined cycle power plant includes a CO2 capture system operatively integrated with a liquefied natural gas LNG regasification system, where cold energy from the regasification process is used for cooling processes within the CO2 capture system or processes associated with it. These cooling systems include systems for cooling lean or rich absorption solutions for the CO2 capture or the cooling of flue gas. The LNG regasification system is arranged in one or more heat exchange stages having and one or more cold storage units. The power plant with CO2 capture can be operated at improved overall efficiencies.
