摘要： PURPOSE:To prevent condensate liquid from overcooling to improve heating-vaporizing efficiency of intermediate thermal medium by heating and vaporizing liquefied natural gas with the intermediate thermal medium and providing filler at a contact portion between condensate liquid drops of the gas and a vaporizer. CONSTITUTION:Filler 5 is disposed in the center of a drum at the boundary between a carbureter 3 for LNG and a vaporizer 4 for liquefied propane gas outside pipe. Thus, LNG is introduced into the carbureter 3 to be heated and vaporized by PG outside pipe, introduced from a line 13 to the outside of the pipe of a heater 11, heated by seawater in the pipe and taken out of a line 14 to the outside of system. On the other hand, the seawater introduced from an end chamber 16 heats and vaporizes LPG in the pipe with the vaporizer 4, and is taken out of a line 17 to the outside of system. LPG condensated outside the pipe of the carbureter 3 is attached to the filler 5 as it drops and contacts PG ascending to have temperature for approximately saturating pressure in the drum. Thus the condensated LPG is prevented from overcooling to improve heating efficiency of a intermediate thermal medium.

摘要： PROBLEM TO BE SOLVED: To provide a liquefied-gas evaporation apparatus which uses sea water or the like as a heat source, can effectively utilize cold heat, and can stably evaporate a liquefied gas. SOLUTION: In an LNG evaporation apparatus 11, an intermediate medium liquid 18 is evaporated in a chlorofluorocarbon evaporator 14 by using sea water, river water or the like as a heat source; and LNG flowing through a heat transfer pipe 15 in an LNG evaporator 12 is heated and evaporated with the resultant intermediate medium vapor 19. The evaporated NG is subjected to heat exchange with sea water in an NG heater 13 to be heated to normal temperature. The intermediate medium liquid 18 cooled by the evaporation of the intermediate medium in the chlorofluorocarbon evaporator 14 is extracted with a pump 20, stored in a chlorofluorocarbon tank 21, pressurized with a pump 22, and transported to an air absorption cooler 35 or a refrigerating warehouse 40. Thus, the output or efficiency of a gas turbine generator can be improved by using cold heat; and the utilization of cold heat for low- temperature cold storage is made possible.

摘要： PROBLEM TO BE SOLVED: To provide a liquefied-gas evaporation apparatus which uses sea water or the like as a heat source, can efficiently recover cold heat, and can stably evaporate a liquefied gas even when the cold heat load varies. SOLUTION: In an LNG evaporation apparatus 11, an intermediate medium liquid 18 is evaporated with a chloro fluorocarbon evaporator 14 by using sea water, river water or the like as a heat source; and LNG flowing through a heat transfer pipe 15 in an LNG evaporator 12 is heated and evaporated with the resultant intermediate medium vapor 19. The evaporated NG is subjected to heat exchange with sea water in an NG heater 13 to be heated to normal temperature. The intermediate medium liquid 18 cooled by the evaporation of the intermediate medium in the fluorocarbon evaporator 14 is supplied to a cold-water-production heat exchanger 20 to cool cooling water. Thus cooled cooling water cools, in an absorbed air cooler 35, air sucked by an air compressor 34, thus enabling the output and efficiency of power generation of a gas turbine generator to be improved.

摘要： PROBLEM TO BE SOLVED: To permit the removal of impurities in LPG, mixed to regulate a calorific power, by a town gas manufacturing device when the town gas using LNG as row material is manufactured. SOLUTION: LNG is preheated by a pre-heater 13 to about -120 deg.C and LPG is mixed into the LNG in a mixer 14. The LNG is pre-heated to a temperature not lower than -120 deg.C whereby the mixed liquid is evaporated by introducing the same into an open rack type main evaporator 11 without generating any problem of the solidification of methanol in the LPG and the temperature of the same can be increased to -50 deg.C--20 deg.C. The mist of LPG is contained in the mixture gas and is collided against heat transfer tubes, baffle plates and the like, provided in a separator 15, whereby the impurities are adhered and agglomerated. LPG constituent is evaporated by a heat source such as sea water or the like and only impurities can be recovered from the lower part of a cylinder. The pre-heater 13 is heated by the mixture gas of the degree of -10 deg.C, which is obtained from the separator 15, while the mixture gas itself is heated to a normal temperature by a sub evaporator 12.

摘要： PROBLEM TO BE SOLVED: To effectively use a cold heat generated in the case of vaporizing a large quantity of LNG. SOLUTION: A cold recovery heat exchanger 1 of a finned U-shaped tube type heat exchanger containing 60 wt.% alcohol water, a vaporizing heat exchanger 2 of a finless U-shaped tube type heat exchanger and a temperature raising heat exchanger 3 are associated in three stages. LNG is vaporized to an ordinary temperature, and cold is used in a cascade manner in a cold using facility 30 such as a frozon food business, a refrigerated warehouse 31, a refrigerated warehouse 32, an air conditioner 33 or the like.

摘要： PROBLEM TO BE SOLVED: To dispense with a residual liquefied gas discharge device, and to stabilize the calorie of the vaporized gas by forming an inlet pipe to feed the raw material from a raw material supply source to a lower header tank in up-grade condition, and installing a bypass to connect the immediately downstream of a main control valve of the inlet pipe to an outlet piping of an vaporizer. SOLUTION: In stopping the operation, supply of the raw material liquefied gas is stopped, a main control valve 2 and an outlet side control valve 5 are closed, and a bypass control valve 7 of a bypass piping 6 is opened to continue vaporization of the liquefied gas left in the vaporizer 1. The pressure in the vaporizer 1 is increased by the vaporized gas. Because the inlet pipe 3 is arranged in up-grade condition toward the vaporizer 1, the residual liquefied gas flows toward the upstream of the inlet pipe 3 by the gravity and is pushed up in the bypass pipe 6. The liquefied gas is vaporized while it passes through a heat radiation pipe 8, and fed into an outlet pipe 4. The liquefied gas is not left in the inlet pipe 3, and fluctuation in calorie caused by the residual heavy component is eliminated in the re-starting.

摘要： PROBLEM TO BE SOLVED: To facilitate adaptation of variation in demand for nitrogen and oxygen or the like and further expand an amount of utilization of cold heat of LNG. SOLUTION: Cooling of raw material air under an operation of an air/ nitrogen heat exchanger 24 and a refining tower 25 is carried out by nitrogen gas forming a Brayton cycle. Nitrogen gas is cooled with an LNG/nitrogen heat exchanger 26, its pressure is increased by a low pressure compressor 28 of a circulating nitrogen compressor 27 and cooled again by the LNG/nitrogen heat exchanger 26, its pressure is increased by a high pressure compressor 29 of the circulating nitrogen compressor 27, it is cooled by the LNG/nitrogen heat exchanger 26, liquefied, thereafter fed into a refining tower 25 and used for separating raw material air. A first power generator 31 rotates a nitrogen expansion turbine 35 and drives it. A second power generator 32 is driven by a gas turbine 39. As natural gas becoming fuel, a part of the natural gas fed out of the device is used. A third power generator 33 is driven by a natural gas expansion turbine 40.
