ABSTRACT:
The present invention relates an improvement to a cryogenic process for the separation of air which produces at least a nitrogen product and is carried out in a distillation column system having at least one distillation column from which the nitrogen product is produced. The distillation column of the distillation column system must comprise a rectifying section. In the process of the present invention, air is compressed, freed of impurities which will freeze out at cryogenic temperatures, cooled to near its dew point and fractionated in the distillation column system to produce the nitrogen product.
The improvement is the operation of the distillation column such that the ratio of downward liquid to upward vapor flow rate (L/V) is no less than 0.65, preferably greater than 0.75, but less than 1.0 in the rectifying section of a distillation column from which the nitrogen product is produced. The flowrates are in moles per unit time.
