摘要： PURPOSE:To prevent intermediate medium charged in a Rankine cycle system from being discharged to the atmosphere upon periodical inspection, and as well to aim at recovering the medium, by recovering the medium, outside of the system by the pressure differential and the liquid head, and as well by charging the recovered medium in the system by the pressure differential. CONSTITUTION:During periodical inspection, when the evaporation of liquefied medium in a medium evaporator 12 is completed after a generator 14 is stopped, the supply of heat source to a heat exchange pipe 41 is ceased. When the condensation and liquefaction of evaporated medium in an LNG evaporator 10 are completed, a valve 57 is closed while a valve 58 is opened to allow LNG to pass through a heat exchange pipe 42 so that a medium recovering unit 16 and a tank 15 are cooled down, resulting in pressure drop. Therefore, liquid medium in the evaporator 10 is recovered to the tank 15 by the pressure differential between the evaporator 10 and the tank 15 and the liquid head. Meanwhile evaporated medium in another Rankine cycle system is extracted by closing a valve 61 and opening a valve 59 into a recovering unit 16, and is condensated and liquefied, being stored in a tank 15. Further, after completion of the inspection the liquefied medium in the tank 15 is charged into the evaporators by the pressure differential, and when the pressure is made uniform, the valve 57 is opened to recharge liquefied medium. After a limited liquid level is established, the valve 61 is closed.
摘要翻译：目的：为了防止在兰金循环系统中充电的中间介质在定期检查时排放到大气中，并且为了恢复介质，通过压差和液体头将介质回收到系统外部，以及通过压差对系统中回收的介质进行充电。构成：在定期检查期间，当中间蒸发器12中的液化介质的蒸发在发电机14停止之后完成时，停止向热交换管41供应热源。当LNG蒸发器10中的蒸发介质的冷凝和液化完成时，关闭阀门57，同时打开阀门58以允许LNG通过热交换管42，使得介质回收单元16和罐15为冷却，导致压降。因此，蒸发器10中的液体介质通过蒸发器10和罐15之间的压差以及液体头被回收到罐15。同时通过关闭阀61并将阀59打开到回收单元16中并被冷凝和液化，从而提取另一兰金循环系统中的蒸发介质，储存在罐15中。此外，检查完成后，液化介质罐15通过压力差被装入蒸发器中，并且当压力均匀时，阀57打开以对液化介质再充电。在建立有限液位之后，阀61关闭。

摘要： PURPOSE:To enable to continue the operation of a medium turbine with no trouble by a structure wherein an oil separator, in which liquefied Rankine medium mixed with oil is separated into the Rankine medium and the oil, is provided in a Rankine cycle type liquefied natural gas (LNG) cryogenic power plant. CONSTITUTION:LNG cryogenic power generating equipment comprise an LNG evaporator 10, a medium pump 11, a medium evaporator 12, a medium turbine 13, a generator 14 and the like. Liquid medium mixed with oil is drained from the medium evaporator 12 through a conduit 70 to an oil separator 16. The liquid medium is vaporized in the oil separator 16 by using the lubricating oil discharged from the shaft seal of the medium turbine 13 as a heat source. The resultant gas medium is returned to the LNG evaporator by opening a valve 61, while the separated lubricating oil is discharged from a conduit 72 by opening a valve 62. In such a manner as mentioned above, bacause no gas medium supplied to the medium turbine is accompanied with liquid medium, the operation of the medium turbine can be continued with no trouble.

摘要： PURPOSE:To improve a rate of recovery of CO and further improve a purity of hydrogen gas by a method wherein hydrogen gas separated under a cooled state of raw gas and a part of liquefied part having as its major constituent CO are extracted and expanded and the raw gas is cooled with circulating gas and liquid nitrogen. CONSTITUTION:Raw gas enters heat exchangers 1 and 2 through conduits 15 and 16 and is cooled by liquid nitrogen and return gas low temperature supplied by a conduit 29. A part of hydrogen gas separated by a separator of low temperature 3 is extracted from the conduits 19 and 21 and expanded by a valve 12 up to about atmospheric pressure. Further, a part of liquefied part having as its major constituent CO is extracted from conduits 20 and 23, expanded by a valve 11 up to about atmospheric pressure and merged with hydrogen gas. The merged circulation gas is rich in hydrogen and expanded up to about atmospheric pressure, so that it becomes a low temperature gas of about -200 deg.C. This gas is supplied to a heat exchanger and then it can be cooled down to a lower temperature than that of the gas having only liquid nitrogen.

摘要： PURPOSE: To stably supply a product CO gas by indirectly detecting a cold end temperature at an outlet of a heat exchanger of the product CO gas for circulation with a pressure controller provided on an upper part of a CO fractioning tower to automatically adjust a regulation valve provided on a bypass line. CONSTITUTION: For example, when the concentration of H in a stock gas grows, the generation of cold in an expansion turbine 5 increases and the temperature of a product CO gas for circulation lowers below a specified value to be liquefied at an outlet of a heat exchanger 1. As a result, the quantity of heat to be supplied for cooking by a reboiler 7 of a CO fractioning tower 4 decreases to reduce the quantity of ascending gas hence causing a drop in the purity of the product gas and in the pressure in the tower. In this case, the pressure in the tower falls below a set value of a pressure regulator 13 provided at an upper part of the CO fractioning tower 4 and with the action of the pressure controller 13, a control valve 11 provided on bypass lines 35 and 36 of the product CO gas for circulation of the heat exchanger 1 is gradually opened to adjust the temperature of the product CO gas at the outlet of the heat exchanger 1 to a specified value. Thus, the quantity of heat supplied by the reboiler 7 of the CO fractioning tower 4 comes up to the specified value thereby enabling stable supply of the product CO gas.

摘要： PURPOSE:To condense and separate methane, etc., and to obtain product CO gas of high purity by expanding liquefied and distilled component obtained from a separator by a valve, then once supplying it to a dehydrogenating tower, evaporating and separating hydrogen, etc., by boiling it by a boiler, and then supplying the liquid of a reboiler to a CO refining tower. CONSTITUTION:Liquefied and distilled component containing CO separated by a separator 4 as a main ingredient is reduced under pressure up to about an ambient pressure by a valve 12, and then fed to a dehydrogenating tower. Since the component contains several to several-tenth of lower boiling point impurities than the CO, the hydrogen, etc., may be evaporated and separated by boiling through a reboiler 10. The reboiler 10 contains only liquid containing CO including methane, etc., of higher boiling point component than the CO almost containing no hydrogen, etc., as a main ingredient. The liquid is refined and separated, product CO gas of 99.9% or higher is extracted from the top of a CO refining tower 7 and fuel gas containing methane as a main ingredient is extracted from the lower part.

摘要： PURPOSE:To shorten starting time of a helium refrigerating cycle by employing a cooling heat exchanger in a vessel for an object to be cooled as for precooling of a heat exchanger in a cold holding tank at the time of starting and as for cooling cooling refrigerant of a refrigerating cycle at the time of normal state. CONSTITUTION:When a helium compressor 1 is started, a turbine inlet valve 4 is closed, and a bypass valve 13 is opened, compressed gas is guided to a cooling heat exchanger 7 via a tube 12, the valve 13. Cooling medium 14 such as liquid nitrogen is, for example, sealed in a vessel 8 for an object to be cooled, and helium gas is cooled to temperature near the cooling medium by thermally exchanging operation with the medium 14. Helium gas is supplied to a heat exchanger 3 in a cold holding tank 11 to cool the exchanger 3, and returned to the compressor 1 via a tube 10. The intermediate temperature of the exchanger 3 is measured by a thermometer 15. When the temperature approaches a temperature at the time of normal state, the valve 13 is closed, the valve 4 is opened, and helium is passed to a helium turbine 5. The exchanger 7 condenses the medium 14 to be evaporated by a heat load 17 to reach a normal state as a helium refrigerating cycle at this time point.
