    Abstract: A liquefaction apparatus that automatically adjusts the load on the liquefaction apparatus correspondingly with an upper limit value of contracted power in different time slots, and which is capable of maximizing the amount of liquefied product produced and of achieving optimum operating efficiency is provided. In certain embodiments, the liquefaction apparatus can include: a production amount calculation unit 91 for obtaining an actual production amount of a liquefied product; a predicted power calculation unit 92 for obtaining a predicted power amount after a predetermined time has elapsed, on the basis of an integrated power value obtained by integrating a usage power; and a power demand control unit 93 for comparing the predicted power amount and a moving average of instantaneous power, and controlling a discharge flow rate of a compressor 3 in such a way as to come infinitely close to a target value, without exceeding the target value, and while using the larger value of the predicted power amount and the moving average of instantaneous power as a value being controlled.

    Abstract: A system for using the waste heat produced from the production of liquefied or solidified heat sink refrigerant in the production of fuel that includes a liquefied or solidified heat sink refrigerant production system, a fuel production system, and a heat exchanger. The liquefied or solidified heat sink refrigerant production system produces waste heat which is transferred through the heat exchanger to power the fuel production system.

    Abstract: A system is set forth to increase the capacity of an LNG-based liquefier in a cryogenic air separation unit wherein, in a low production mode, the nitrogen that is fed to the LNG-based liquefier consists only of at least a portion of the high pressure nitrogen from the distillation column system while in a high production mode, a supplemental compressor is used to boost the pressure of at least a portion of the low pressure nitrogen from the distillation column system to create additional (or replacement) feed to the LNG-based liquefier. A key to the present invention is the supplemental compressor and the associated heat exchange equipment is separate and distinct from the LNG-based liquefier. This allows its purchase to be delayed until a capacity increase is actually needed and thus avoid building an oversized liquefier based on a speculative increase in liquid product demand.

    Abstract: A method of manufacturing a breathable, life-supporting cryogenic liquid mixture including the steps of: producing a stream of treated natural air having substantially all the carbon dioxide and moisture removed therefrom; admixing a quantity of mixing gas containing nitrogen in a proportion greater than natural air thereby to producing a product gas mixture having a desired oxygen/nitrogen ratio and liquefying this said mixture in a heat exchanger against a suitable chilling fluid.
