    摘要: A process and device for evaporating an oxygen-enriched working fluid by indirect heat exchange include introducing an oxygen-rich working fluid into the evaporation passages of an evaporator where it is partially evaporated. A first oxygen-enriched gas and a portion of the oxygen-enriched working fluid that remains liquid are drawn off from the evaporation passages. At least a part of the portion that remains liquid is returned to the evaporation passages as a circulation liquid by a conveying device. The conveying device for the circulation liquid injects a lift gas.

    摘要: The process is used for the recovery of krypton and/or xenon by low-temperature separation of air. Compressed and purified feed air (1, 1A, 1B, 29) is introduced into a rectification system for nitrogen-oxygen separation, which has a high-pressure column (2) and a low-pressure column (3). An oxygen-rich liquid (42) is removed at a first point from the low-pressure column (3). At least a first portion (43) of the oxygen-rich liquid (42) is re-introduced in the low-pressure column at a second point, whereby a mass exchange section (44) is arranged between the first and second points on the low-pressure column. An additional liquid (35) is drawn off from a third point of the low-pressure column (3), which is arranged at the level of the second point or below it, said liquid introduced into the evaporation chamber of a first condenser-evaporator (4) and partially evaporated there. A krypton- and xenon-containing fraction (138) is drawn off from the evaporation chamber of a first condenser-evaporator and introduced into the evaporation chamber of a second condenser-evaporator (27). A krypton-xenon concentrate (125) is drawn off from the second condenser-evaporator (27).

    摘要: In a process for supplying a pressurized gas, a pressurized gas at a high production pressure is produced as an end product by separating a gaseous mixture in a separator apparatus (3, 5), a liquid to be pressurized is stored in a store (9), storing liquid is tapped, and it is pressurized with a pump (11) and at least part of the pressurized liquid is sprayed in a sprayer (27) to produce the pressurized backup gas (29) having substantially the same pressure or a pressure higher than the pressurized gas to be produced, liquid is circulated in a substantially vertical duct (13), optionally within the cold box (33) of the separator apparatus, and at least part of the duct length is at a level above the sprayer and before and/or after starting up the pump (11), liquid is sent from the duct to the sprayer where the liquid is sprayed to provide pressurized backup gas having substantially the same purity or a purity higher than the pressurized gas to be produced (31).

    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).

    摘要: Air is separated by cryogenic distillation comprising the steps of feeding compressed, cooled and purified air to a high pressure column where it is separated into a first nitrogen enriched stream at the top and a first oxygen enriched stream at the bottom. At least a portion of the first oxygen enriched stream is fed to an intermediate pressure column to yield a second nitrogen enriched stream at the top and a second oxygen enriched stream at the bottom. At least a portion of the second nitrogen enriched stream is sent to a low pressure column or to a top condenser of an argon column, and at least a portion of the second oxygen enriched stream is sent to the low pressure column. A third oxygen enriched stream is separated at the bottom and a third nitrogen enriched stream is separated at the top of the low pressure column. A heating gas is sent to a bottom reboiler of the low pressure column, and at least a portion of the third oxygen enriched stream is removed at a removal point. A first argon enriched stream containing between 3 and 20% argon is removed from the low pressure column, and the first argon enriched stream is sent to the argon column having a top condenser. A second argon enriched stream, richer in argon than the first argon enriched stream, is recovered at the top of the argon column and a fourth oxygen enriched stream is removed at the bottom of the argon column. The argon column operates at a pressure at least 0.5 bar lower than the pressure of the low pressure column.
