    摘要： The process and the apparatus serve to generate electric energy in a combined system comprising a power station and air treatment plant. The power station has a first gas expansion unit (300) which is connected to a generator for generating electric energy. The air treatment plant has an air compression unit (2), a heat exchanger system (21) and a tank (200) for liquid. In a first operating mode, feed air is, in the air treatment plant, compressed in the air compression unit (2) and cooled in the heat exchanger system (21), a storage fluid containing less than 40 mol% of oxygen is produced from the compressed and cooled feed air and the storage fluid is stored as low-temperature liquid (101) in the tank (200) for liquid. In a second operating mode, low-temperature liquid (103) is taken from the tank (200) for liquid and vaporized or pseudovaporized under superatmospheric pressure and the gaseous high-pressure storage fluid (104) produced in this way is expanded in the gas expansion unit (300). In the second operating mode, the (pseudo)vaporization of the low-temperature liquid is carried out in the heat exchanger system (21) of the air treatment plant.

    摘要： A process comprising: cooling natural gas with a heat exchanger and a first expander. The heat exchanger cools the feed natural gas to temperature higher than the outlet temperature of the expander, reheating the expander outlet stream in a first cold passage of the heat exchanger to slightly below the temperature of the feed natural gas to the heat exchanger, passing the cold outlet stream from the heat exchanger into a second expander wherein it is partly liquefied, separating the outlet stream of second expander into liquid and vapour fractions, collecting the liquid fraction for use as LNG product, reheating the vapour fraction in a second cold side passage of the heat exchanger to substantially the same temperature as the temperature of the feed natural gas to the heat exchanger, recycling the reheated vapour fraction partly as feed to the first expander and partly as feed to the heat exchanger.

    摘要： Provided is a method for operating a fuel supply system for a marine structure such as an LNG carrier having a BOG reliquefaction apparatus and a high-pressure natural gas injection engine (e.g., an ME-GI engine), which can efficiently supply fuel to the high-pressure natural gas injection engine and minimize energy consumption in the BOG reliquefaction apparatus. A method for operating a fuel supply system to supply fuel to a high-pressure natural gas injection engine is provided. The fuel supply system includes a BOG compression unit configured to receive and compress BOG generated in a storage tank, a reliquefaction apparatus configured to receive and liquefy the BOG compressed by the BOG compression unit, a high-pressure pump configured to compress the liquefied BOG generated by the reliquefaction apparatus, and a high-pressure gasifier configured to gasify the liquefied BOG compressed by the high-pressure pump. The fuel supply system includes a recondenser installed at an upstream side of the high-pressure pump, and the recondenser recondenses a portion or all of the generated BOG by using liquefied gas supplied from the storage tank. During a ballast voyage process, all of the BOG is supplied to and recondensed by the recondenser, and an operation of the reliquefaction apparatus is interrupted.
