    摘要： Process and installation for the production of gaseous oxygen and/or gaseous nitrogen under pressure, of the type in which air is distilled in a double distillation column (11) comprising a low pressure column (13) operating under a so-called low pressure, and a medium pressure column (12) operating under a so-called medium pressure. All the air to be distilled is compressed (in 1, 3, 7)to at least one high air pressure substantially greater than the medium pressure, and the compressed air is cooled to an intermediate temperature, and a portion of it is expanded in a turbine (8) to the medium pressure, before introducing it into the medium pressure column (12). The air which has not been expanded is liquefied, then introduced after expansion (in 20, 21), into the double column. At least one liquid product withdrawn from the double column is brought to the production pressure, and this liquid product is vaporized by heat exchange with at least one portion of the air to be distilled in the course of cooling. An additional cycle fluid withdrawn from the double column (11) or destined for this latter, is reheated, compressed (in 3; 30, 31) to a high cycle pressure, cooled, a fraction thereof expanded (in 8; 35) with the production of external work, and the rest of the compressed additional cycle fluid is liquefied.

    摘要： Process and installation for the production of variable flow rates of at least one pure component by fractionation of a mixture in a distillation apparatus (15), containing structured packing (17) and dimensioned to handle a nominal flow rate of the mixture at nominal pressure. To obtain higher production than the nominal production, there is increased proportionately to the ratio of the productions, the flow rate of the mixture distilled in the apparatus (15). Also increased is the operating pressure of the apparatus so as to increase the flooding limit of the apparatus under similar proportions. Preferably, the mixture is air. There is a compressor (3) for the mixture to be fractionated designed for nominal capacity and, upstream of the latter, a blower (1). Alternatively, there can be a compressor (3) for the mixture to be fractionated designed for maximum capacity. There is a heat exchange line (9) in which is effected an indirect heat exchange between the mixture to be fractionated which is cooled therein and at least one product of the apparatus (15) which is reheated therein, the heat exchange line being designed for operation at nominal production, and in which the ratio between the number of passages allotted to the mixture to be fractionated and the number of passages allotted to at least one product of the apparatus is variable according to the production regime that prevails.

    摘要： A process and installation for the separation of air in a cryogenic distillation apparatus (24) comprising a distillation column (30, 42) and in which the supplied air is separated to produce a fraction rich in oxygen and a fraction rich in nitrogen as products. The purities of these products are maintained substantially constant during variations of demand of either product or of the flow rate or of the pressure of the supplied air by introducing an excess of liquid rich in nitrogen into the distillation apparatus when the demand for the product or the flow rate of the supplied air increases, and by withdrawing an excess of liquid rich in nitrogen from the distillation apparatus, and storing this liquid, when the demand for the product or the flow rate of the supplied air decreases. The apparatus comprises a medium pressure column (30) and a low pressure column (42) and a reflux conduit (44; 11, 12) which permits a reflux liquid to be withdrawn from the medium pressure column (30) and to be injected into the low pressure column (42).
