In this process, during at least one phase of the treatment cycle, the gas outflow is increased or decreased locally in at least one marginal region of the packing. Application to drying/CO removal of atmospheric air intended to be distilled, or to the separation of gaseous mixtures by pressure modulated adsorption.

Process and reactor for treating a gas by means of a regenerable active packing

An apparatus for improving the flow of fluid to be treated in boundary regions of a mass (2) of particulate material. The apparatus has at least one deflecting surface (4), making an angle with the main direction of the flow of fluid passing through the mass, in the boundary region in order to divert the flow of the fluid locally. The apparatus may be used in plants for purifying or separating gas mixtures.

Plant for treating at least one fluid and use for the separation of at

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.

Heat and material exchanging device and method of manufacturing said

A jacket encloses 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) has a lower end opening out laterally which includes a projecting obstacle (7) in the vicinity of this lower end. In this way, liquid that would otherwise accumulate on the vertical walls of the jacket, where it would participate relatively little in heat and material exchange, is instead diverted toward the interior.

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.

The gas which comes from a source passes through a regulating valve, then through a heat exchanger and is sent to the network through a production duct. The heat exchanger thus acts as a muffler. Application to the supplying of gas from air separation.

Apparatus for supplying a gas to a gas utilizing network

The case 2 of the container 1 having a vertical axis X-X contains two adsorbent beds 3,4 in the form of sleeves retained by three cylindrical grates 5, 6, 7. The intermediate grate 6 is axially rigid and radially flexible while the innermost and outermost grates 5,7 are axially flexible and radially rigid. This enables the container and the adsorbent beds to support without damage the successive heating and cooling stages in the course of the adsorbent regeneration stages. Application to the purification of large amounts of air intended to be distilled.
