Oxygen is vaporized in channels of oxygen-layers against heat exchange fluid passing through channels of heat exchange layers. The walls of the oxygen layer channels are formed of ferrous alloy and have a cross-section, in a plane perpendicular to the direction of flow, having a thickness at its narrowest of at least about 10%, and on average at least about 15%, of the combined hydraulic mean diameters of the adjacent channels, and the ratio of cross-sectional area, in said plane, of the walls to the cross-sectional area of the channels is no less than about 0.7.

摘要： The invention relates to a method for liquefying a stream rich in hydrocarbons, especially a stream of natural gas, by the indirect exchange of heat with the refrigerants in a closed-circuit cascade of mixed refrigerants. According to the invention, said closed-circuit cascade of mixed refrigerants consists of at least 3 circuits of mixed refrigerants, with each circuit comprising different refrigerants. The first of the three mixed refrigerant circuits is used for pre-cooling (E1), the second for liquefying E2), and the third for super-cooling (E3) the hydrocarbon-rich stream (1) to be liquefied. The method provided for in the invention reduces specific energy consumption and investment costs since the three circuits of mixed refrigerants are or can be optimally adjusted to the enthalpy temperature curves of the hydrocarbon-rich stream to be liquefied and the refrigerant mixtures.

摘要： A dephlegmator includes a feed gas passage and a refrigerant passage. A feed gas introduced into the feed gas passage from the bottom is heat-exchanged with a refrigerant passing through the refrigerant passage. Components having low boiling points are withdrawn as rectified gases from the top, and components having high boiling points are discharged as condensates from the bottom. The refrigerant passage is divided into a first section on the top side and a second section on the bottom side by a bridgewall. In the first section, a liquid or gas-liquid two-phase refrigerant is introduced from the bottom of the refrigerant passage so as to flow parallel to the feed gas. In the second section, a gas fraction of the refrigerant discharged from the first section flows.

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.
