Abstract:
The invention relates to a rolled heat exchanger with several pipes that are wound around a central pipe, with a casing that delimits an external space around the pipes and with a liquid distributor for distributing liquid in the external space. According to the invention, the liquid distributor is designed as a pipe manifold that has a main channel (21) and several distributing arms (22) that are flow-connected to the main channel (21).
Abstract:
A column for mass exchange between a liquid and a gas includes at least one pair of adjacent exchange plates, formed by an upper exchange plate and a lower exchange plate. The column also includes a drain shaft for passing liquid between the upper exchange plate and the lower exchange plate, and a recessed inlet cup located underneath a bottom end of the drain shaft. The bottom of the inlet cup is recessed relative to the surface of the lower exchange plate. The recessed inlet cup extends over only one part of the cross-section of the bottom end of the drain shaft.
Abstract:
In recovering pure argon product, air is separated in a rectification system, comprising at least one air separating column (9), a crude argon column (17) and a pure argon column (25). A crude argon fraction (24) is withdrawn from the crude argon column (17) and introduced at an intermediate locality into the pure argon column (25). The head of the pure argon column (25) is cooled by indirect heat exchange (29). From the pure argon column (25) a residual fraction (31) containing essentially nitrogen is withdrawn overhead and from the bottom a pure argon fraction (26) is withdrawn. The mass transfer in the pure argon column (25) is brought about at least in part by a packing (33, 34).
Abstract:
The invention relates to a column (1), with a section (9), in which a filling (10) is arranged in the form of a large number of fillers or a packing, a liquid distributor (100) for distributing a liquid (F) on that filling (10), a distribution space (101) of the liquid distributor (100), via which the liquid (F) can be distributed to that filling (10) of the column (1). According to the invention, it is provided that in the distribution space (101) of the liquid distributor (100), an additional means (20) is arranged, which forms a large number of passages (21) for the liquid (F) that is to be distributed.

Abstract:
The invention concerns a fluid-distributor for a substance-exchange column, the fluid-distributor comprising at least one main duct and a plurality of distributor ducts. The distributor ducts are connected for flow purposes to the main duct and are provided with fluid-discharge openings. In order to attain particularly high-quality distribution, the effective length (L) of the fluid-discharge openings is smaller than their diameter (D).
Abstract:
An apparatus and process for cryogenic separation of air are described which utilize a pipe distributor or a channel distributor for liquid distribution. The air separation apparatus contains a rectifying column having at least one section equipped with packing materials, wherein a liquid distributor is positioned thereabove. The main channel and/or the distributing channels of the liquid distributor are closed over at least a portion of their top. Also described is a liquid distributor for use in a mass transfer column.

The invention relates to a rolled heat exchanger comprising several pipes wound around a central pipe, a casing delimiting the external space around the pipes and a liquid distributor for distributing liquid in the external space. According to the invention, the liquid distributor is embodied in the form of a pipe manifold comprising a main channel (21) and several distributing arms (22) which are fluidically connected thereto.
Abstract:
In the process for the low temperature separation of air, purified and cooled air is fed into a distillation system comprising at least one rectification column and there is rectified by a counter-current material exchange between a vapor and a liquid phase. The material exchange in at least one section in at least one rectification column is brought about by a packing having a specific surface area of at least 1000 m.sup.2 /m.sup.3.
