    Abstract: The invention relates to a method for the simultaneous removal of nitrogen oxides and laughing gas stream containing nitrogen oxides and laughing gas, wherein a first catalyst that contains cobalt and, as support, an inorganic metal oxide, and a second catalyst that contains iron and, as support, an inorganic metal oxide, are used. In particular the method is carried out in such a way that (a) the gas stream containing nitrogen oxides and laughing gas is reacted with a reducing gas, the reducing gas comprising a saturated hydrocarbon, in the presence of the first catalyst, and (b) the gaseous product from step (a) is reacted with a reducing gas, the reducing gas comprising a saturated hydrocarbon, in presence of a second catalyst. The catalyst system can be used for the treatment of off-gases from a nitric acid plant.

    Abstract: Method and device for converting CO on one side of a membrane with the addition of water to give CO2 and H2O. During this reaction H2 passes through the membrane. On the other side of the membrane H2 is combined with oxygen and burned. This oxygen can be supplied in the form of air and can originate from a fuel cell or fed thereto. CO and H2 originate from a fuel cell.

    Abstract: Method and assembly for extracting energy from a flowing fluid. It is proposed to regard all devices of the assembly together as one flow body. In particular those devices on the upstream side of the assembly are set such that they exert lateral (horizontal and/or vertical) forces on the fluid flow, as a result of which flows are produced that guide fast fluid through the energy-extracting devices and guide slow fluid precisely away therefrom. The assembly includes a wind farm and the devices that generate the lateral forces are a type of vortex generators for the atmospheric boundary layer; more particularly they are horizontal or vertical wind turbines positioned at an angle to the wind.

    Abstract: A heat exchanger is used between the stripper section and rectifier section. The heat exchanger ( 10 ) has channels closed on all sides with an end inlet and end outlet for the related section. A compressor is fitted between the sections. According to the invention the heat exchanger is a so-called compact heat exchanger, that is to say a heat exchanger made up of a series of adjacent plates ( 15, 16 ) between which channels ( 11, 12 ) closed on all sides for the related section are delimited. These channels ( 11, 12 ) extend essentially vertically and are so constructed that all liquid contained therein is able to move towards the bottom of the section concerned. The flow cross-section of the channels of the stripper/rectifier section changes depending on the process carried out therein.
