Abstract:
A rotary liquefied natural gas boil-off compressor has a series of compression stages. A gas passage passes through the series of compression stages. The gas passage extends through and is in heat exchange relationship with cooling means in the form of indirect heat exchangers. Each of the heat exchangers is cooled by LNG supplied from a pipeline. Flow control valves are provided for controlling the flow of LNG to the heat exchangers respectively. The valves are controlled in response to temperature sensors respectively, so as to maintain the inlet temperature of each of the compression stages at a chosen sub-ambient temperature or between chosen sub-ambient temperature limits.
Abstract:
A corvette ship-type equipment system includes standard-equipment segments, such as an energy generator, an energy distributor, a drive and an automation segment, and a hull which is adapted to the size and specific requirements on the corvette ship-type equipment system. In order to construct standard equipment-segments for a corvette ship-type equipment system which is technically and constructively simple and economical in terms of cost, at least one of the standard-equipment segments, such as the energy generator and/or the energy distributor and/or the drive and/or the automation segment is constructed from standard units or components which correspond to the requirements of the corvette ship-type equipment system and which are arranged in the hull of the boat and which can be built into the hull of the boat according to the different boat or ship-type equipment systems.
Abstract:
Marine LNG carrier and method of operating the marine LNG carrier. The LNG carrier carries LNG in at least one tank. Gas composed of evaporated LNG within the at least one tank is removed. The gas is fed to at least one gas consuming prime mover of the LNG carrier. Power is provided with the at least one gas consuming prime mover. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.
Abstract:
A method and apparatus to amplify the magnetic field in an electromagnetic circuit is provided. Amplification factors of several orders of magnitude may be obtained. The system is applicable to a number of different systems, including melt levitation and electromagnetic pumping and propulsion. One embodiment of the invention uses a non-conducting permeable core wound around a dielectric core. An alternating voltage source is connected to a solenoid which is wound around a section of the permeable core. The permeable core has a gap within which a flux concentrating cold crucible is provided. Melt levitation processing takes place within the cold crucible.
