Abstract
Abstract A gas treatment or separation apparatus includes a vessel (2) containing a bed (18) of particulate material. Within the bed (18) there is located a plurality of distensible hollow members (30) each capable of being placed in communication with a source of fluid under pressure. The members (30) restrain movement of the particulate material.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
72 words
Gas treatment or separation apparatus including at least one vessel (2) which contains a bed (18) of particulate material and which has at least one gas inlet (14) and at least one gas outlet (12), charactersied in that the bed (18) receives a plurality of distensible hollow members (30) extending generally longitudinally of the bed, said members (30), being able to be placed in communication with a source of fluid under pressure.
Claim 2
Dependent Claim
41 words
Apparatus as claimed in claim 1 for separating a gaseous mixture by pressure swing adsorption, additionally including a compressor to compress the incoming gas mixture, and characterised in that the distensible members (30) communicate directly with the outlet of the compressor.
Claim 3
Dependent Claim
33 words
Apparatus as claimed in claim 1, characterised in that the distensible members (30) are connected to a pressurised source of a gas mixture of different composition from the gas mixture to be separated.
