    Abstract: A process for cryogenic separation of feed air by increasing the capacity of an LNG-based liquefier is provided to perform essential cooling of a product with an increased productivity when at least a part of the product is required to be present in a liquid state, while not increasing the dimension of the liquefier. A process for cryogenic separation of feed air comprises that: (a) the feed air(100) is compressed and impurities are removed from the air, and then the air is supplied to a cryogenic air separation unit(1) including a main heat exchanger and a distillation column system; (b) the feed air is cooled in the main heat exchanger(110); (c) the cooled air(112) is separated in the distillation column system into a nitrogen-enriched stream and oxygen-enriched stream; (d) the distillation column system includes a high-pressure column and a low-pressure column; (e) the feed air is separated in the high-pressure column into a high-pressure nitrogen stream(174) and a crude liquid oxygen stream(158) supplied to the low-pressure column; (f) the low-pressure column separates the crude liquid oxygen stream into an oxygen product stream and a low-pressure nitrogen stream(180); (g) the high-pressure column and the low-pressure column are thermally linked to each other, at least a part of the high-pressure nitrogen is collected at the bottom(sump) of the low-pressure column and condensed in a reboiler/condenser by a boiling oxygen-enriched liquid used as reflux to the distillation column system; and (h) when at least a part of the product is required to be present in a liquid state, a coolant is discharged from liquefied natural gas by feeding nitrogen from the distillation from a liquefier unit for providing essential cooling and nitrogen is compressed through multiple steps by using at least one preliminary compressor and is liquefied via indirect heat exchange with the liquefied natural gas. To increase the capacity of an LNG-based liquefier(2) including a supplementary compressor distinguished from the preliminary compressor, (i) in a low-capacity mode, the nitrogen supplied to the liquefier comprises at least a part of the high-pressure nitrogen, and (ii) in a high-capacity mode, the pressure of at least a part of the low-pressure nitrogen is increased to the pressure of the high-pressure nitrogen to produce pressurized nitrogen as a feeding material for the LNG-based liquefier.
