Abstract
An air gas separation plant comprising, in the direction of circulation of the air stream: a compression means that makes it possible to compress the air stream to a pressure P1 of between 1.15 bar abs and 2 bar abs, an adsorption unit of TSA type, and a cryogenic distillation unit, with the adsorption unit comprising at least two adsorbers A and B each having a parallelepipedal casing arranged horizontally and comprising: an air stream inlet and an air stream outlet, a fixed bed adsorbent mass, likewise of parallelepipedal shape, the faces of which are parallel to the faces of the casing; and a set of volumes allowing the air stream to pass through the adsorbent mass horizontally, over the entire cross-section and throughout the entire thickness thereof.

An air gas separation plant comprising, in the direction of circulation of the air stream:
- a) a compressor configured to compress the air stream to a pressure P1 of between 1.15 bar abs and 2 bar abs;
- b) a cryogenic distillation unit;
- c) an adsorption unit of TSA type comprising at least two adsorbers A and B each having a parallelepipedal casing arranged horizontally,
- wherein the adsorption unit further comprises:
- an air stream inlet and an air stream outlet;
- a fixed bed adsorbent mass, likewise of parallelepipedal shape, the faces of which are parallel to the faces of the casing;
- and
- a set of volumes allowing the air stream to pass through the adsorbent mass horizontally, over the entire cross-section and throughout the entire thickness thereof.
