  • Patent number: 10391447
    Abstract: A method and plant for capturing CO2 from a CO2 containing exhaust gas (1), where the exhaust gas is compressed (10) and thereafter cooled (13, 15, 22) before the exhaust gas is introduced into an absorber (30), where the exhaust gas is brought in counter-current flow with an aqueous CO2 absorbent solution (49), to give a lean exhaust gas (31) that is withdrawn from the absorber (30), reheated 22, 13) against incoming compressed exhaust gas, and thereafter expanded (34) and released into the atmosphere (4), where the aqueous CO2 absorbent solution is an aqueous potassium carbonate solution, and that the steam and CO2 withdrawn from the regenerator (40) is cooled in a direct contact cooler (61) by counter-current flow of cooling water (62), to generate a gaseous flow (70) of cooled CO2 and steam that is withdrawn for compression and drying of the CO2, and a liquid flow (64) of cooling water and condensed steam that is withdrawn and flashed (80), to give a cooled liquid phase (84) that is recycled as cooling wa

  • Publication number: 20130119667
    Abstract: A method for producing electrical power and capture CO2, where gaseous fuel and an oxygen containing gas are introduced into a gas turbine to produce electrical power and an exhaust gas, where the exhaust gas withdrawn from the gas turbine is cooled by production of steam in a boiler (20), and where cooled exhaust gas is introduced into a CO2 capture plant for capturing CO2 from the cooled exhaust gas leaving the boiler (20) by an absorption/desorption process, before the treated CO2 lean exhaust gas is released into the surroundings and the captured CO2 is exported from the plant, where the exhaust gas leaving the gas turbine has a pressure of 3 to 15 bara, and the exhaust gas is expanded to atmospheric pressure after leaving the CO2 capture plant. A plant for carrying out the method is also described.

  • Publication number: 20100126137
    Abstract: A combustion installation including a combustion device with a combustion space for combustion of a fuel and an oxygen-containing gas to a combustion gas in the combustion space and a membrane device is described. The membrane device is arranged for the flow of air, past a membrane in a second compartment of the membrane device, to be in the same direction as the flow of combustion gases, past the membrane in a first compartment of the membrane device.

  • Publication number: 20100031859
    Abstract: A combustion installation comprising a combustion device for combustion of a fuel and an oxygen-containing gas to a combustion gas and a method for such combustion is described. A nozzle means is arranged for injection of the fuel into the combustion device and a membrane device for supplying oxygen to the combustion gases for production of the oxygen-containing gas, wherein the combustion device comprises at least a first inlet for the oxygen-containing gas and an outlet for the combustion gases. The combustion installation comprises at least a first ejector including the nozzle means and the first inlet, wherein the nozzle means and the first inlet are arranged to drive the flow of oxygen containing gas and fuel through the combustion device.

  • Publication number: 20060230762
    Abstract: A method for producing, on an SiC substrate, SiC homoepitaxial layers of the same polytype as the substrate. The layers are grown on a surface of the SiC substrate, wherein the surface is inclined relative to the (0001) basal plane at an angle higher than 0.1 degree but less than 1 degree. An homoepitaxial growth is started by forming a boundary layer with a thickness up to 1 ?m.
