    摘要: A separation process, involving an adsorber containing at least one adsorbent with an inlet and outflow, involves the following stages of the cycle:--stage I, repressurization from the low pressure of the cycle;--stages II and III during one of which the high pressure of the cycle is reached; and stage IV, depressurization/purging, during which the low pressure of the cycle is reached. Each stage (I to IV) involves a fixed gas flow (F) at one end of the adsorber and a free gas flow (.lambda.) at the other end of the adsorber, the fixed flows (F) addressing the inlet (E) and outlet (F) ends of the adsorber from one stage (I to IV) to the next. The process is particularly applicable to the production of oxygen from air.

    摘要: A gas treatment bottle comprises at least one gas dispenser (24;50) and has a distributor (25;51) intended to be fixed in a gas treatment bottle (10) in front of an inlet or outlet orifice (18;56). The distributor (25;51) has a head (26) which covers the orifice and has an openworked end wall (28) and an openworked side wall (30), typically inclined in the direction of the end wall (28) and surrounding it. The degree of openworking in the side wall (30) is greater than the degree of openworking in the end wall (28).

    摘要: The equipment, for example of the PSA type, comprises gas circulation elements for passing the gas horizontally through an adsorbent (3), which comprise, on at least one vertical side of the adsorbent, a gas distribution volume comprising a first subvolume (5; 9) adjacent to the adsorbent, and a second subvolume (6; 10) separated from the first subvolume by a wall provided with passages (40) having cross-sections and/or a distribution which are selected so as to reduce the variations in local flow rate along the adsorbent. The equipment is particularly useful in separating gases from air.
