  • Patent number: 9732981
    Abstract: The present invention relates to a method and equipment for recovering heat from exhaust gas removed from an industrial process, such as an electrolysis process for the production of aluminum. Heat is recovered by means of an extraction/suction system, where the exhaust gas contains dust and/or particles. The heat is recovered as the exhaust gas being brought into contact with heat-recovery elements. Flow conditions and the design of the heat recovery elements are such that the deposits of the dust and/or particles on the surfaces stated are kept at a stable, limited level. In preferred embodiments, the heat-recovery elements have a circular or an extended, elliptical cross-section and may be equipped with fins or ribs.

  • Publication number: 20120151887
    Abstract: The invention is separator for separating a fluid flow of gas with droplets (G, L), comprising an inlet (10) for the gas to be separated to a rotor (4) with a mesh (5) for coalescing the droplets (L) and releasing coalesced liquid (L?) from a peripheral part (50) of the rotor (4). Novel features of the separator is that—the mesh (5) generally forms an axial passage for said gas (G) from the inlet (10), through said rotor (4), to an outlet (20) for liquid depleted gas (G?), and—the rotor (4) with the mesh (5) is arranged for transporting the coalesced liquid (L?) laterally out of the axial passage to a wall (6) arranged for receiving the coalesced liquid (L?).

  • Publication number: 20120006744
    Abstract: The invention relates to a reactor for treatment of waste water for being subject to both anoxic/anaerobic and aerobic treatment within one single reactor volume. The anoxic/anaerobic reaction zone is separated from the aerobic reaction zone by a separator which also works as a hydrodynamic separator between the two reaction zones. The reactor makes it possible that the effluent water has a lower proportion of suspended solids and also that it produces less sludge than reactors of comparison. The reactor is further more energy efficient than prior art reactors. Several reactors according to the invention may be arranged in parallel so as for the inlet waste water may be treated in a modular way, and thus allowing the maintenance of the units to be facilitated.

  • Patent number: 7993433
    Abstract: The invention relates to a new method for removing and recovering of acid gases from a gaseous mixture in an absorption plant by adding an organic acid to a stream of the rich absorbent in the desorber in order to release acid gas by shifting the acid gas equilibrium towards the gas side, and the organic acid is subsequently separated from the absorbent. With this method, the energy consumption of the process is substantially reduced. The invention also relates to an apparatus for performing this method.

  • Publication number: 20100251763
    Abstract: In the transportation and processing of natural gas liquid nitrogen and liquid carbon dioxide is used in a heat exchanger process to liquefy natural gas supplied by a field site. The liquefied natural gas is transported to a regasification plant where cold energy in a part of the liquefied natural gas in an air separation device is used to produce liquid nitrogen and oxygen, natural gas. The oxygen is combusted in a power production plant, which captures the carbon dioxide produced by the combustion. This carbon dioxide is liquefied it using another part of the liquefied natural gas. The liquid nitrogen and liquid carbon dioxide is then transported to be used for further liquefaction of natural gas supplied by the field site.
