摘要： The heat exchanger can be used for the vaporization of a pressurized liquid and comprises at least one passage way (P) for a liquid extending in a first direction, being provided with exchange waves that are substantially parallel to the first direction and comprising at least one redistribution area associated with at least one lateral collector in an intermediate area of the length thereof, in addition to being provided with deviation waves extending in at least one second direction forming an angle with the first direction, whereby the redistribution area takes up the entire width of the passage way, in a crosswise position with respect to the first direction, whereby the deviation waves communicate with the exchange waves. The deviation waves are essentially as rigid as the exchange waves. The invention can be used with exchangers in pumped air-distillation devices.

摘要： An evaporator has main passages placed in a heat-exchange relationship, an arrangement for forming a pool of the liquid to be evaporated so that it flows through at least a first of the main passages, and a device for introducing a refrigerant into at least a second of the main passages so that evaporation of the liquid is ensured. The or each first main passage possesses, in the free section transverse to the direction of flow of the liquid to be evaporated, at least one continuous free-flow region sufficiently extended to allow the liquid to get round a deposit of impurities, or, the main passages being bounded by vertical plates having a substantially similar contour and being parallel and spaced apart so as to form the flat main passages, at least one first main passage is either narrower than the corrugation nor an auxiliary passage, or contains one or more closed auxiliary passages which extend over most of the length of the heat exchanger body parallel to the direction of flow of the liquid to be evaporated, the walls of the auxiliary passage(s) touching the plates defining the main passage.

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).

摘要： A reservoir for the storage of gas under high pressure comprises an enclosure portion (2) which is uninsulated and an enclosure portion (2A) which is insulated. The two portions (2A, 2B) are connected by an insulated passage (18) insulated from the enclosure portions. The uninsulated portion (2B) defines a gaseous sky limiting the instantaneous pressure drops during withdrawal of liquid from the insulated portion (2A) to decrease the response time of the heating of an external circuit to maintain pressure. Used particularly in safety installations of a principal source for the production of gas under high pressure.
