Abstract: Disclosed is a packing made up of a stack of plates, having been shaped to form corrugations in the plate and assembled to form a cross-corrugated packing block for a mass and/or heat transfer application, wherein the material of the packing plates is an open-pore metal foam, and in that the specific surface area of the packing is greater than 500 m2/m3 and in that the thickness (e) of the plate is less than 2 mm before the shaping operation.

Abstract: The invention relates to a heat exchanger comprising parallel plates and spacers arranged in parallel and defining i) rough primary channels and ii) secondary channels arranged so as to exchange heat. Said heat exchanger comprises a primary liquid inlet to be fluidically connected to a primary liquid dispenser. Each rough primary channel has the shape of a prism having a polygonal cross-section and consisting of a plurality of essentially flat faces. The primary channels comprise rough primary channels. Each rough primary channel has microstructure elements which are distributed along the entire length of the channel and have dimensions of between 1 ?m and 300 ?m.

Abstract: The invention relates to a distribution device having a container having side walls and a bottom with perforations; a distributor arranged beneath the container and provided with distribution channels that each have a polygonal cross-section; and mechanical connection bodies between the distributor and the linear elements, which extend beneath the distribution channels and fluidically connect the distribution channels to the linear elements when the distribution device is built into the contacting assembly.

Abstract: The invention relates to a method for cooling, purifying and separating a gaseous mixture containing at least one impurity, in which the gaseous mixture is cooled to a temperature no higher than the temperature at which the at least one impurity solidifies in a heat exchanger having cooling passages, the cooling passages being at least partially covered with a coating and/or physically treated and/or chemically treated, the coating and/or the treatment serving to limit or even prevent the solidified impurity from forming and/or adhering to a surface of the passages; at least one portion of the solidified impurity exiting the cooling passages of the heat exchanger is collected; and the gaseous mixture is withdrawn from the heat exchanger.

Abstract: In a method for separating air by separation at sub-ambient temperature, a first heat pump, using the magnetocaloric effect, exchanges heat between a cold source at sub-ambient temperature and a hot source at sub-ambient temperature, thus providing at least some of the separation energy, and a second heat pump, using the magnetocaloric effect, exchanges heat between a cold source at sub-ambient temperature and a hot source at ambient temperature thus providing at least some of the cold needed to maintain the refrigeration balance of the method, the separation taking place in a single column at a pressure of below 2 bara.

Abstract: In a method for separation at sub-ambient temperature, a mixture of fluid at sub-ambient temperature is sent to a system of separation columns comprising at least one separation column, a fluid enriched in a lighter component of the mixture leaves the top of one column of the system and a fluid enriched in a heavier component is withdrawn from the bottom of one column of the system, the cold source of a heat pump using the magnetocaloric effect is thermally connected to a first zone of one column of the system and the hot source of the same heat pump is thermally connected to a second zone of the same or of another column of the system.

Abstract: Installation for treating a fluid comprising, in a section of a horizontal shell ring (1) a first particulate material filling a volume (V2), a deflector comprising 2 volumes V3 delimited by the internal shell of the shell ring and on the other hand by lower surfaces S3a and S3b making with a horizontal plane an angle (?) greater than the angle of repose of the first particulate material, a volume (V4) formed of a membrane backing up against the two volumes (V3) of the deflector over the entire length of the section of the shell ring, and of a second particulate material with which the volume (V2) is filled; the second particulate material being contained in the space formed by the membrane and the internal shell of the shell ring, the volumes V3 and V4 being situated in the upper half of the cross section of the horizontal shell ring.
