A plant for the separation of gases by adsorption, which is of the PSA type, includes, in a container (1) of vertical axis, at least one annular bed of particulate material (5, 6) supported on a lower wall (9) which is itself supported by a perforated prismatic wall (11) bearing on a domed end (2) of the container. A lower wall (9), advantageously in the form of a very wide inverted V (9A, 9B), has no part forming an angle (.alpha., .beta.) in excess of 15.degree. with the horizontal. The plant is useful in the separation of gases from air.

[ What is claimed is:] [1.] Plant for the separation of gases by adsorption, comprising:a container having a domed lower end including a central gas passage and a lateral gas passage;at least one annular volume, of vertical axis, of at least one particulate material delimited at the bottom by a transverse lower wall having a thickness less than that of the domed lower end; andat least a first prismatic wall provided with apertures between the domed end and the lower wall;wherein the annular volume is supported on the transverse lower wall of which no part forms an angle in excess of 15.degree. with the horizontal, and which is supported by the prismatic wall bearing on the domed end.
