Abstract: The invention concerns a method for heat treatment of carbon materials and especially carbon black in a plasma process for increased order in the nanostructure, i.e. an increased degree of graphitization in the carbon black particles. The process consists in an upgrading of commercial carbon black qualities and non-graphitic carbon materials. The heat treatment is conducted in a plasma zone where the residence time and power supplied are controlled in order to ensure that the carbon material does not sublimate. Thus the carbon which is supplied to the plasma zone is prevented from being transformed and reformed into a new product.

Abstract: A heat exchanger has been developed with a helical insert (9) permanently mounted in a housing (2). Between the windings in the insert (9) there is formed a helical channel (20) for one heat exchange medium. The insert (9) is designed with a channel (10) for the second heat exchange medium. The heat exchanger is designed with a central tube (13) which is axially movable and rotatable. The central tube (13) is designed with scraper elements for removal of deposits in the channel (20). In one embodiment the scraper element is formed by a helical insert (15) of the same design as the insert (9). The insert (15) is designed with a channel (16) for the second heat exchange medium. In a further embodiment the central tube (13) is designed with one or more scraper arms (23) which may be liquid-cooled. Deposits are often formed on the heat transfer surfaces. A cleaning cycle is performed by means of axial movement of the insert (15) which is mounted on the cenral tube (13) towards the permanently mounted insert (9), thus causing the heat transfer surfaces to touch each other. A rotating movement is then performed, e.g. a part of a turn, while the surfaces are close to each other or in contact with each other, thus causing the deposits on the two surfaces to be rubbed or scraped off and thereby cleaning the channel (20).

Abstract: When loading petroleum from a subsea petroleum deposit or a subsea petroleum store on to a vessel (1) on the surface, especially a production ship, there are employed one or more risers (11) which lead from the petroleum deposit or petroleum store to the vessel. A floating element (3) which is located in the water and which is connected via the risers (11) to the petroleum deposit or the subsea store, is brought into the area of a balcony (2) provided in or at the vessel's (1) side and is coupled thereto. Petroleum is passed via the risers from the deposit/store through the floating element (3) to the vessel (1) via couplings (7). If a special situation should arise the floating element (3) with the risers (11) can be released from the couplings (7) on the vessel's balcony (2) and released from the ship (1) when the floating element (3) is deballasted.

Abstract: A method and a plant for treatment of fly ash are described, wherein heavy metals are separated and wherein there is formed a leaching resistant slag. The treatment takes place in a reactor (2) and the fly ash is introduced into an oxidizing gas stream which is heated to at least 2500 DEG C in a plasma generator (1). The fly ash melts and forms liquid drops of slag. A carbonaceous or hydrocarbonaceous material is added to the gas stream. This burns and supplies extra energy to the process. The ratio of oxygen and carbon is regulated in such a manner that the ratio CO2/CO + CO2 is kept within the limits 0.4 - 0.9. Heavy metals in the fly ash such as zinc and lead are thereby reduced and pass into the gas phase. The gas is discharged from the reactor (2), cooled and washed and metal oxides are separated. The gas will also contain chlorine and sulphur which are separated in a gas scrubber. The slag is collected in the bottom of the reactor (3) and can be continuously tapped via a slag lock (9). The slag's content of CaO and SiO2 can be regulated by the admixture of a slag-forming material with a high content of SiO2. A slag is thereby obtained with excellent leaching resistance.

Abstract: A method for removing and preventing emissions into the atmosphere of carbon dioxide (CO2) from exhaust gases from heat engines, particularly gas turbines, installed on offshore platforms for the production of oil and/or gas, which is characterized by the following steps: (a) natural gas and air are introduced into a heat engine in which natural gas is converted to mechanical energy, (b) the exhaust gas from the heat engine is passed through a heat recovery plant, preferably a waste heat boiler, for recovery of the heat content in the exhaust gas in the form of steam, (c) after emitting heat in the heat recovery unit whereby the temperature of the gas has been reduced to 20-70 DEG C, the exhaust gas is passed to an absorption column containing an absorption liquid, where the carbon dioxide is absorbed in the said liquid, and the thereby purified exhaust gas, generally free of carbon dioxide, is vented to the atmosphere, (d) the absorption liquid which contains CO2 is passed to a stripping column where the CO2 is removed from the absorption liquid by means of heating to a temperature of 120-150 DEG C, (e) the thereby regenerated absorption liquid which is generally free of CO2 is recycled to the absorption column and the separated CO2 gas is passed to a compression stage for compression and utilization and/or disposal in a suitable manner.
