    摘要: This installation comprises subgroups of permeators (SG1 to SG3), each subgroup comprising a permeator (4A to 4C) or several permeators mounted in parallel, and having an inlet (12A to 12C), a permeate outlet (14A to 14C) and a non-permeate outlet (16A to 16C). The non-permeate outlet of a first subgroup (SG1, SG2) is connected to the inlet of a second subgroup (SG2, SG3), and at least one of the subgroups has closure elements (22A to 22C) for its permeate outlet when the real feed flow rate is below the nominal feed flow rate by a predetermined quantity.

    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 device for separation of gas by adsorption, of the so-called VSA or MPSA type, comprises, between a utilization line (L) and a source (S) of gaseous mixture to be separated, at least one module (M) comprising in series a reversible rotary machine (R), typically a Roots machine, an adsorber (A) and a shut-off valve (V), the rotary machine (R) being alternately actuated, in one direction during a first phase of pressurization and of production and then, in the other direction, during a second phase of depressurization and desorption. Used particularly in the production of small and medium volumes of oxygen in modular installations.
