摘要： The invention relates to a method for separating air by means of cryogenic distillation in a system of columns, in which two single-stage air superchargers are connected in series and coupled to two turbines, which expand the air that was not supercharged. The superchargers supercharge the cooled high-pressure air in an exchange line in which the oxygen from the system of columns is vaporized.

摘要： A method for controlling a pump arrangement comprising a fluid delivering pump having a pump drive, a bypass line having a bypass valve for routing fluid back from an outlet side of the pump to a reservoir is disclosed. During ramping up the pump drive to a predetermined target rotational speed, the bypass valve is controlled to reduce a volume flow through the pump so that the volume flow, at a respective delivery height, lies between a cavitational volume flow and the cavitational volume flow increased by a predetermined maximum volume flow deviation.

摘要： An annular divided wall column for the cryogenic rectification of air or constituents of air is provided. The annular divided wall column includes a first annular column wall and a second annular column wall disposed within the first annular column wall to define an annulus column region and an interior core column region. The present annular divided wall column further includes structured packing elements disposed within at least the annulus column region as well as a ring-shaped cantilevered collector; and a ring-shaped distributor disposed in the annulus column region above or below the plurality of structured packing elements. The thermal expansion and contraction of the second annular column wall in a radial direction and in an axial direction is independent of the thermal expansion and contraction of the first annular column wall in the radial and axial directions.

摘要： A method and apparatus for argon recovery in which an impure argon stream is separated from air within a cryogenic air separation unit having an argon rejection column and a reflux type argon condenser disposed internally within the lower pressure column. An impure argon stream is subsequently recovered from the argon rejection column and purified within an integrated adsorbent based argon refining and purification subsystem to produce product grade argon. The waste stream from the adsorbent based argon refining and purification subsystem is recycled back to the argon rejection column so as to improve the argon recovery.

摘要： The argon recovery of an air distillation plant is increased by increasing the argon rectifier reboil and simultaneously decreasing the nitrogen stripping reboil. No additional power and minimal added equipment is required. Referring to FIG. 1, two separate argon rectifier reflux condensers (7 and 9) are provided, either for a single argon rectifier or optionally as shown for two separate argon rectifiers (12 and 13). Kettle liquid is partially evaporated in reflux condenser 7 and the liquid residue is further evaporated in reflux condenser 9 to a vapor of differing (higher) O.sub.2 content. The two vapor stream are separately fed to different heights of column 2, separated by countercurrent contact zone 11.

摘要： The invention relates to a method for a low-temperature air separation in which an air separation unit is used comprising a first rectification column and a second rectification column. The first rectification column is operated at a first pressure level, and the second rectification column is operated at a second pressure level below the first pressure level. Fluid which is oxygen-enriched compared to atmospheric air is drawn from the first rectification column in the form of one or more first material flows. At least one fraction of the fluid which has been drawn from the first rectification column in the form of the one or more first material flows is heated in a heat exchanger; a fraction of the fluid which has been heated in the heat exchanger is compressed using a compressor and is returned to the first rectification column.

摘要： The invention relates to a process for cryogenic fractionation of air using an air fractionation plant comprising a rectification column system comprising a high-pressure column operated at a pressure level of 9 to 14.5 bar, a low-pressure column operated at a pressure level of 2 to 5 bar, and an argon column. It is envisaged that a recirculating stream is formed using the second tops gas or a portion thereof, which is heated, compressed, cooled again, and after partial or complete liquefaction or in the unliquefied state is introduced partially or completely, or in fractions, into the first rectification column and/or into the second rectification column. The present invention also relates to a corresponding system.
