A radial adsorber comprising: an adsorbent mass containing particles, a cylindrical shell ring extending along a longitudinal axis that is vertical when the adsorber is in operation, an external grid and an internal grid arranged in such a way as to be permeable to the gas and impermeable to the particles, the internal grid and external grid between them forming an annular volume housing the adsorbent mass, an internal chamber located between the vertical longitudinal axis and the internal grid, an external chamber located between the external grid and the shell ring, the internal chamber and external chamber being intended for the circulation of the gas, the external grid being formed by a plurality of wires and a plurality of supports, the supports being mounted transversely to the wires, the supports and the wires being mounted secured to one another.

Radial adsorber with radial circulation of gas

A process for producing a purified gas stream having impurities, using a production unit for producing a gas stream and a storage reservoir. The process includes producing a first gas stream by means of the production unit. Storing at least a portion of the first gas stream in the storage reservoir. Extracting, from the storage reservoir, a second gas stream corresponding to at least one portion of the first stream polluted by the impurities. Purifying the second gas stream by transfer of at least one portion of the impurities contained in the second gas stream into the first gas stream. And recovery of the purified gas stream at the output of the purification.

Method for producing a gaseous flow using a storage tank

Process for conditioning a container including a granular material A enabling the adsorption of the nitrogen contained in a feed gas stream, including a step of injecting, into the container, a gas or a gas mixture G such that the adsorption capacity of the material A with respect to G is less than 10 Ncm/g at 25&#xb0; C. and 1 atm.

Disclosed in the present invention are a cold box steel structure and method for prefabricating and transporting the cold box steel structure. The cold box steel structure is a cuboid architecture, and has a long edge, a wide edge and a high edge of lengths L, W and H respectively, wherein L&#x3e;W and L&#x3e;H; the cold box steel structure comprises first and second rectangular base faces, each being an outer surface of the cuboid architecture comprising the long edge and the wide edge, and the cold box steel structure is prefabricated as two partial components taking a plane parallel to the rectangular base faces as a boundary; the total height of a first partial cold box steel structure component thereof, taking the first rectangular base face as a first transportation bottom face, is h, and the total height of a second partial cold box steel structure component, taking the second rectangular base face as a second transportation bottom face, is h; if the height difference between the transportation bottom face and the ground or a water surface is h, then (h+h) corresponds to a transportation height of the first partial cold box steel structure component, and (h+h) corresponds to a transportation height of the second partial cold box steel structure component; the transportation height of either of the cold box steel structure components should be smaller than a maximum permitted transportation height h.
