Abstract: PROBLEM TO BE SOLVED: To provide a fuel stabilization system capable of removing dissolved oxygen from fuel to raise fuel temperature and being adapted to different demand conditions for removing oxygen. SOLUTION: This fuel stabilization system 10 is provided with a fuel tank 12 for supplying fuel to an engine 15 by a fuel pump 14. Dissolved oxygen is removed from fuel by a fuel stabilization assembly 16 provided with a plurality of oxygen removers 18, 20, 22, 24, 26 arranged in parallel. A part 30 of dissolved oxygen is removed from fuel by each fuel oxygen remover and is exhausted to the outside. Temperature of flowing-in fuel is within a scope of limit temperatures for preventing promotion of generation of insoluble substance under the presence of dissolved oxygen. Since fuel flowing out of the fuel stabilization assembly 16 contains less amount of dissolved oxygen, it is possible to heat fuel up to higher temperatures. Fuel is moved and heated by a heat transfer device 32. Efficiency of the engine is improved by improved temperature characteristic of fuel. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: A deoxygenator includes a plurality of permeable membranes spirally wou nd about an exhaust tube for removing dissolved oxygen from a hydrocarbon fuel. The permeable membrane is spirally wrapped about the exhaust tube and defines fu el passages and exhaust passages. The fuel passages and exhaust passages alternate such that each fuel passage is bounded on each adjacent side by an exhaust passage. An oxygen partial pressure differential is generated across the permeable membrane to draw dissolved oxygen from fuel in the fuel passage. The dissolved oxygen is then communicated through openings about the circumference of the exhaust tu be and out the deoxygenator.

Abstract: A fuel stabilization system includes a first deoxygenator and a second deoxygenator both for removing dissolved oxygen from a hydrocarbon fuel. The first and second deoxygenators are arranged in parallel or series to sequentially remove a portion of dissolved oxygen from the hydrocarbon fuel. The arrangement of several deoxygenators for a single fuel stream improves removal of dissolved oxygen and provides for scalability of the fuel system to meet application specific demands. The arrangement also provides for the preservation of partial syste m functionality in the event of the failure of one of the deoxygenator modules .

Abstract: A deoxygenator (10) includes a plurality of permeable membranes (22) spirally wound about an exhaust tube (14) for removing dissolved oxygen from a hydrocarbon fuel. The permeable membrane (22) is spirally wrapped about the exhaust tube (14) and defines fuel passages (28) and exhaust passages (30). The fuel passages (28) and exhaust passages (30) alternate such that each fuel passage (28) is bounded on each adjacent side by an exhaust passage (30). An oxygen partial pressure differential is generated across the permeable membrane (22) to draw dissolved oxygen from fuel in the fuel passage (28). The dissolved oxygen is then communicated through openings (34) about the circumference of the exhaust tube (14) and out the deoxygenator (10).
