Abstract
A device for decomposition of a multicomponent gas, especially air, and its enrichment in at least one component, whereby a supply gas line connects a gas source to a first device having a separation forechamber, and a second separation chamber. A branch line is connected to the forechamber from which a secondary product gas can be removed. Each of the separation chambers can be operated in the favorable pressure range for an effective separation, especially when operating at low supply gas pressures. The configurations of the separation chambers are oriented to the required demand for the individual components. Also, the efficiency of a permeation device having a permeation chamber and a retentate chamber is improved. For this purpose, the separation forechamber and the permeation chamber are operated in parallel and both are supplied with feed gas, whereby the permeate chamber of the permeation device can be flushed with the waste gas from the separation forechamber across the branch line.
