摘要： Method and device for generating gaseous compressed nitrogen by the low-temperature separation of air in a distillation column system, having a pre-column, a high-pressure column and a low-pressure column. The feed air is compressed, purified in a purification apparatus and cooled. A first sub-flow of the cooled feed air is introduced in a predominantly liquid state into the distillation column system. A gaseous fraction from the pre-column in introduced into the liquefaction chamber of a pre-column head condenser with liquid formed therein fed as reflux into the pre-column. A first gaseous nitrogen product fraction is drawn from the high-pressure column, heated, and obtained as first gaseous compressed nitrogen product. At least a part of the second sub-flow is introduced into the evaporation chamber of the pre-column head condenser. A third sub-flow of the cooled feed air is expanded to perform work and subsequently introduced into the liquefaction chamber.

摘要： The method and the apparatus are used to obtain oxygen and nitrogen at superatmospheric pressure by low-temperature separation of air in a rectification column system. Compressed and purified feed air (1, 3) is introduced into a pressure column (4). Liquids (5, 8) from the lower region and, respectively, from the upper or middle region of the pressure column (4) are fed into the low-pressure column (7). A third liquid fraction (17) from the lower region of the low-pressure column (7) is evaporated in indirect heat exchange (12) with condensing vapour (11) from the upper region of the pressure column (4), at least a portion of the vapour (22, 24, 26, 27) obtained in the process being introduced into the low-pressure column (7). Condensate (13) is fed into the pressure column (4); A pressurized nitrogen fraction (10, 14, 15) is extracted as product from the upper region of the pressure column (4). The pressure of the third liquid fraction (17) from the lower region of the low-pressure column (17) is increased upstream of the indirect heat exchange (12); that portion (24) of the vapor which is obtained during the indirect heat exchange and led back into the low-pressure column is expanded (25) before being introduced (27) into the low-pressure column (7).

摘要： A method of installing a structured packing in an exchange column, the structured packing having a surface area density in the range of about 500 m2/m3 to about 675 m2/m3 includes a plurality of corrugated plates disposed in vertically parallel relation. Each plate has at least one aperture and a plurality of regularly spaced and substantially parallel corrugations disposed in crisscrossing relation to the corrugations of an adjacent plate. The apertures have an equivalent diameter of less than about 4 millimeters but greater than about 2 millimeters. The corrugations have a corrugation angle (&agr;) relative to horizontal in the range of about 40° to about 60°. Each corrugation, when approximated to be substantially a triangular cross-section, has an included angle (&bgr;) defined by two sides of the corrugation in the range of about 90° to about 100°. The structured packing is used in exchange columns for exchanging heat and/or mass between a first phase and a second phase in processes such as cryogenic air separation.

摘要： A packing material capable of improving the uniformity of liquid distribution and of achieving a preferable gas-liquid contact reaction, even in the case where the specific surface area of the packing material is small, includes a plurality of projections provided on the surface of a thin plate, and a plurality of holes provided respectively between the projections. In one embodiment, the transfer extension of each projection is larger than a longitudinal extension thereof, so that descending liquid flows downward while being transversely dispersed by the projection. The holes are provided between the projections so that they do not obstruct the transfer dispersion of liquid at the projection. Moreover, the holes accelerate the transverse dispersion of liquid, or the dispersion of liquid between front and rear surfaces of the thin plate, by the surface tension of the liquid. As a result, excellent uniformity of liquid distribution can be obtained on the surface of the thin plate. An improved air separator containing the packing material incorporated into a rectifier for performing gas-liquid contact reaction is also disclosed.

The improvement comprises effectuating intimate contact of the liquid and vapor phase streams utilizing a structured packing to effectuate the intimate contact in at least those regions of the distillation column system where argon concentration is within the range from about 0.6 to about 75 volume percent, and operating the process such that the densimetric superficial gas velocity in those regions is at least 0.06 feet per second. The present invention also relates to a method for improving a cryogenic distillation apparatus having at least one distillation column for the separation of mixtures containing oxygen and argon, comprising the step of replacing the distillation trays with a structured packing in at least those regions of the distillation column system where the concentration of argon is in the range from about 0.6 to about 75 volume percent.

摘要： A method and apparatus to obtain a compressed nitrogen product by low-temperature fractionation of air in a distillation column system. The system has a high-pressure column, a low-pressure column, a main condenser, and a low-pressure column top condenser. Bottoms liquid from the low-pressure column is evaporated in the top condenser and the gas formed is decompressed to perform work that drives a cold compressor. A gaseous first compressed nitrogen product stream from the high-pressure column is warmed in the main heat exchanger. A further gaseous nitrogen stream from the low-pressure column is compressed in the cold compressor and warmed as a second compressed nitrogen product stream in the main heat exchanger. The cold compressor overcomes a pressure differential which is at least equal to two thirds of the pressure differential between the top of the high-pressure column and the top of the low-pressure column.
