Abstract: A method for autothermal or substantially autothermal catalytic dehydrogenation of hydrocarbons is described. A hydrocarbon containing feed gas is optionally mixed with steam and/or hydrogen, is pre-heated and is introduced into a catalytic bed of a reactor, where an oxygen containing gas is fed directly into the catalytic bed from one or more oxygen supply tube(s) (3) each tube (3) having one or more opening(s) distributed in the catalytic bed.

Abstract: A system for detecting a subterranean reservoir or determining the nature of a subterranean reservoir (35) whose position and geometry is known from previous seismic surveys. An electromagnetic field (42,43) is applied by a transmitter (37) on the seabed (33) and detected by antenna (38) also on the seabed (33). A refracted wave component (43,43c) is sought in the wave field response, to determine the nature of any reservoir present.

Abstract: A method of treating a hydrocarbon-bearing measure such as an oil-bearing rock formation ( 13 ). The method comprises: injecting water containing a source of vitamins, phosphates and an electron acceptor such as nitrate into the formation at first location ( 10 ) and allowing anaerobic bacteria, which are either already present in the formation ( 13 ) or which are introduced simultaneously to multiply using the oil as their main carbon source. This establishes a biomass layer ( 16 ) which acts to dissociate the oil from the rock formation ( 13 ). The dissociated oil is removed via an outlet ( 15 ). The vitamins are supplied by means of a controlled-release medium.

Abstract: The present invention concerns a method for preparing a CO 2 -rich gas stream for injection purposes or deposition, and a hydrogen rich gas stream, the method comprising the following steps: a) natural gas and H 2 O are fed into a one-step reforming process for preparing a gas mixture comprising CO 2 and H 2 under supercritical condition for water from about 400° C. to about 600° C. and pressure from about 200 to about 500 bar in the reforming reactor; b) the gas mixture from a) is separated into a H 2 -rich and CO 2 -rich gas stream, respectively. The invention also comprises use of CO 2 -rich gas stream for injection into marine formations, and use of H 2 -rich stream for hydrogenation, as a source of energy/fuel in fuel cells and for production or electricity.

Abstract: A system for removing water from natural gas which comprises: bringing the natural gas into contact with a liquid including an absorbent for the water; subjecting the natural gas and liquid to turbulent mixing conditions thereby causing the water to be absorbed by the absorbent; and separating a natural gas phase with reduced water content and a liquid phase including the absorbent and absorbed water. The mixing is conducted in a turbulent contactor (11) including a gas inlet (15), a liquid inlet (16), an outlet (104) leading to a venturi passage (105) and a tube (106) extending from the outlet (104) back upstream. The tube (106) may be perforated and/or spaced from the periphery of the outlet (104).

Abstract: A rudder, especially for water vessels, which in its one end is connected with the vessel's hull (1) and comprising a main rudder blade (3) and rudder flaps (5, 6) arranged to be turnable with respect to the main rudder blade (3). The new traits of the invention are that the main rudder blade (3) is arranged to be in a fixedly anchored centre position with respect to the hull (1), and having two or more rudder flaps (5, 6) mounted leading and trailing on the main rudder blade (3) and arranged to steering the vessel at high speeds, and that the main rudder blade (3) is arranged releasable from its fixedly anchored center position, and arranged to be turnable as a whole in the usual manner, especially for steering the vessel at lower speeds.

Abstract: The present invention relates to a cell for the production of electric energy by reaction between hydrogen peroxide or oxygen, and aluminium or lithium or a mixture thereof, and hydroxyl ions in water, where the cathodes are cylindrical and based on radially oriented carbon fibres attached to a stem of metal. The novel feature of the invention is that by utilizing such cathodes in a cell with circulating electrolyte, it is possible to keep the concentration of oxidant in the electrolyte low and thus obtain high utilization of the reactants.

Abstract: A method for laying a pipeline on the sea bed from a lay barge in order to achieve controlled thermal expansion, comprises the following steps: Feeding out of the pipeline having a radius of initial residual curvature from a pipeline reel, preferably via a stinger to a curvature device where a radius of reversal curvature is applied to the opposite side of the pipeline with respect to the radius of initial residual curvature when the pipelines is passing through the curvature device. The curvature device straightens out the pipeline to longer, mainly straight portions with length having a radius of residual curvature which is larger than a desire minimum radius of residual curvature. The curvature device exposes shorter portions of the pipeline with a length for a radius of counter curvature forming the thermal expansion loops having a radius of residual curvature which is less than a desired maximum radius of residual curvature for the thermal expansion loops. The result is controlled pipe deflection under thermal expansion of the pipeline in operation position on the seabed and under operational loads, in that the deflection of the pipeline may appear in the thermal expansion loops of the pipeline.
