摘要:
An apparatus and method of use for treating at least one fluid, in a container that holds at least one mass of a particulate material between two perforated walls. Near the upper part of the mass, at least one deflector extends from the first wall towards the second wall. Fluid flows through the walls horizontally, and the deflector is positioned at an angle to this horizontal fluid flow direction. With this particular apparatus configuration, an area close to the second wall and opposite the adjacent end of the deflector is formed, which is generally free of particulate matter; thus, resulting in a more efficient treatment process.

This bath reboiler-condenser (4), of the brazed plate type, includes vaporization passages (11) subdivided into a plurality of stacked vaporization regions (13A to 13C) each of which is immersed in a partial height bath (28A to 28C), and means for feeding the top vaporization region (13C) with liquid. The vaporization regions (13A to 13C) are spaced vertically and each region is entirely open at its top and bottom ends. Application to the main reboiler-condensers of double air distillation columns.

This corrugated strip comprises on its lower edge, in front view, at least one downwardly projecting motif (9) whose contour is such that, if &agr;m and &agr;M designate the ends of the algebraic value of the angle that the tangent to the contour forms with the horizontal direction, then −&agr;m>&agr;0 and &agr;M>&agr;0, wherein &agr;0 designates a predetermined angle at least equal to 5°. The corrugated is particularly useful in air distillation columns on board floating oil platforms or barges.
摘要:
Input/output chamber for a fluid, for part of a body (1) of an apparatus in which this fluid circulates, this part of the body including a face (3) for inlet or outlet of the said fluid, the chamber (6A) being intended to be connected with a leaktight joint to this face. At least part of the chamber consists of at least one spherical or ellipsoidal portion (20A) and of sectors of cones (22A) tangential to this spherical or ellipsoidal portion.

Heat and material exchange device including a stack of fixed ventilators to promote gas mixing, each ventilator being constituted by four deflectors whose mean normals are inclined and generated one after another by rotation about vertical axes, the sum of the four angles of rotation being 360.degree.. The ventilators are stacked in successive horizontal layers amidst which each deflector forms a part of two adjacent ventilators turned in opposite directions and such that there is sufficient space between two adjacent deflectors for the passage of gas. The deflectors are pierced by at least one hole so as to promote passage of the liquid to the underside of the deflectors. At least some of the deflectors are connected to at least one of their neighbors in a same horizontal plane by a common edge segment so as to permit lateral division of the liquid between deflectors. The device is useful in columns for separating the components of air, or mixtures of carbon monoxide, nitrogen, hydrogen or hydrocarbons, or for the separation of isotopes.

This device comprises a packet of corrugated plates (3) each disposed in a generally vertical plane, the corrugations being oblique and descending in opposite directions from one plate to the following plate. Each corrugation valley (5) having a lower end opening out laterally includes an projecting obstacle (7) in the vicinity of this lower end.Application in air distillation columns.

This distributor comprises: a peripheral crown; a series of vertical partitions fixedly mounted on the crown at both ends thereof and extending parallel to one another; sealingly closing means bounding, between the vertical partitions, alternate spaces for collecting gas and liquid; means enabling the upward evacuation of the gas contained in the spaces for collecting gas; and a perforated bottom disposed at the base of each liquid collecting space and sealingly connected to the or each adjacent vertical partition and to the crown. Application to air distillation columns.
摘要:
A system for sampling cryogenic liquids, and an air separation unit provided with at least one such system. The cryogenic liquid is introduced into a vaporizer, through heat exchange with the compressed air. The liquid passes through the vaporizer generally downwards. The walls of the vaporizer that are intended to come into contact with the cryogenic liquid are maintained at a temperature above the sublimation temperature or the boiling point of the least volatile impurity contained in this liquid. Downstream of the vaporizer, a gaseous phase coming from the vaporization of the cryogenic liquid is withdrawn and at least some of the gaseous phase is sent to an analyzer.
摘要:
A plate-type heat exchanger containing a number of stacked dividing plates of roughly uniform thickness (e), at least one passage, and at least one fin. The minimum thickness (e′) of the fin is 0.8 times greater than the thickness (e) of each dividing plate(s).

The invention concerns a corrugated packing module for treating a fluid delimited by two channels (18). It comprises a running zone (4) whereof the channels define ridge lines (26) having a global sloping direction (D1) relative to a general direction of circulation (Df) of the fluid. The strip comprises a transition zone (6, 8) adjacent to the running zone (4). Each ridge line (26) of the transition zone (6, 8) extends inside a specific zone centered on a curve (A) which extends tangentially the ridge line (26) of the running zone (4). The radial width (Lr) is 10% of the corresponding radius of curvature of the curve (A). The radius of curvature (Rc) of the curve (A) is at all points 1.5 times greater than the hydraulic diameter (Dh) of a channel (18). The invention is applicable to air distillation columns.
