    摘要： In a process for separating air by cryogenic distillation, an oxygen-rich stream having a first oxygen purity of less than 98 mol % oxygen is withdrawn from the column system and sent to a customer, an oxygen-rich liquid stream having a second oxygen purity, possibly lower than 98 mol % oxygen, is sent to a storage tank, liquid is periodically withdrawn from the storage tank and sent to a back-up reboiler, to produce a back-up product, and a liquid stream having a third oxygen purity, lower than the first purity, is withdrawn from the bottom of at least one column of the column system and/or from the auxiliary reboiler and sent to the storage tank as a purge stream during a stoppage in the operation of the column system.

    摘要： The present invention relates to a method and apparatus for producing a pressurized product stream product by cryogenic rectification. A main heat exchanger, used in the cryogenic rectification, warms a pumped product stream composed of oxygen-rich or nitrogen-rich liquid and thereby produces the pressurized product stream. Layers of the main heat exchanger are designed such that a reduction in the heat transfer area provided within the main heat exchanger for warming the pumped product stream occurs at a location at which the temperature of the pumped product stream exceeds either the critical or a dew point temperature of such stream. The reduction in heat transfer area leaves regions of the layers able to heat or cool another stream that is used in connection with the cryogenic rectification. Such other stream can be a refrigerant stream that allows the introduction of additional refrigeration to increase production of liquid products.

    摘要： Methods and apparatus for treating a liquid bath of oxygen. A liquid bath of at least 70 mol % of oxygen is located at the base of a cryogenic distillation column. The bath is continuously boiled by an aluminum reboiler. A portion of the liquid bath is purged to prevent a build up of inflammable impurities in the bath. A portion of the purge is sent to a second reboiler, which is less inflammable than the first reboiler. Oxygen boiled by the second reboiler is sent back to the column, and a portion of the oxygen rich liquid bath treated by the second reboiler is also purged. The invention also relates to an apparatus of carrying out this method.

    摘要： The invention relates to a process and apparatus for producing nitrogen by low-temperature fractionation of air in a rectification system which has a high-pressure column (4) and a low-pressure column (5). Feed air (1, 3) is introduced into the high-pressure column (4). An oxygen-containing liquid fraction (11) is removed from the high-pressure column (4) and fed into the low-pressure column (5). Gaseous nitrogen (18) is extracted from the low-pressure column (5) above a mass transfer section (25), which has at least one theoretical or practical plate, and is at least partially condensed in a top condenser (17) by indirect heat exchange with a refrigerant (13). High-purity nitrogen is removed from the low-pressure column below the mass transfer section (25), and is obtained as a nitrogen product (26, 27, 30). The process and apparatus have a refrigeration-supply system, in which a refrigeration fluid (31) flows. At least part of the refrigeration fluid from the refrigeration-supply system is introduced into the low-pressure column (5) above the mass transfer section (25).

    摘要： An apparatus for melting a metal provided with a metal melting furnace (10) for melting a metallic raw material with a flame of an oxygen fuel burner (11) to which oxygen is supplied as a combustion assisting gas; and an oxygen supply source for supplying oxygen as a combustion assisting gas to the oxygen fuel burner (11). The metal melting furnace (10) has a preheating section (13) for preheating the metallic raw material above a melting section (12) to which the oxygen fuel burner (11) is attached and a reduced section (14) located between the melting section (12) and the preheating section (13), the reduced section having an inside diameter smaller than those of the melting section and preheating section. The oxygen supply source is a pressure swing adsorption separator (30) employing an adsorbent which adsorbs preferentially atmospheric nitrogen and supplying a low-purity oxygen having an oxygen content of 65 to 94% to the oxygen fuel burner (11).
