  • Patent number: 10022669
    Abstract: A process for removing N2O and NOx from offgases by catalytic decomposition of N2O by means of iron-containing zeolite catalysts and catalytic reduction of the NOx by means of reducing agents, the deNOx stage connected downstream of the deN2O stage being operated at inlet temperatures of T<=400° C., and the inlet gas for the deN2O stage comprising water and having a selected N2O/NOx ratio, and the operating parameters of temperature, pressure and space velocity of the deN2O stage being selected so as to result in an N2O degradation of 80 to 98%. Under these conditions, a degree of NOx oxidation of 30-70% is established at the outlet of the deN2O stage, which is defined as the ratio of the molar amounts of NO2 to the total molar amount of NOx. The result of this is that the downstream deNOx stage can be operated under optimal conditions. Also provided is an apparatus for carrying out the process.

  • Patent number: 8951475
    Abstract: A chemical heat accumulator includes a receptacle, a first reaction vessel, and a second reaction vessel. The first reaction vessel is hermetically connected to the receptacle and supplied with water from the receptacle. The first reaction vessel contains a chemical compound that causes a hydration reaction with the water from the receptacle to generate water vapor by a heat of reaction, and causes a dehydration reaction by receiving heat. The second reaction vessel is hermetically connected to the first reaction vessel and supplied with the water vapor from the first reaction vessel. The second reaction vessel contains a chemical heat storage material that generates heat by causing a hydration reaction with the water vapor from the first reaction vessel and stores heat through a dehydration reaction caused by receiving heat. The chemical heat storage material is thermally in contact with an object to be heated.

  • Patent number: 8951488
    Abstract: The present invention relates to a method of cleaning a carbon dioxide rich flue gas stream containing oxygen. The method includes heating the flue gas stream to a temperature suitable for selective catalytic reduction (SCR) of NOX; and reducing at least some of the NOX in the heated flue gas stream to N2 by SCR. Heating of the flue gas stream includes removal of residual oxygen contained in the flue gas by catalytic oxidation of a suitable carburant. The present invention further relates to a gas processing unit.

  • Publication number: 20150037238
    Abstract: Disclosed is a method for recovering carbon dioxide from exhaust gas, more particularly, a method for recovering carbon dioxide from exhaust gas for saving the cost for recovery of carbon dioxide by decreasing energy required for recycling a carbon dioxide absorbent solution. In particular, a circulating solvent, whose heat of vaporization and/or sensible heat is lower than that of a solvent of an absorbent solution introduced to a recycling tower, is supplied to the lower portion of the recycling tower and mixed with the heated absorbent solution. As a result, the pressure inside the recycling tower is maintained so that carbon dioxide released from the absorbent solution is discharged to a storage tank/drum.
