Patent DE-4214551-A1 (DE)
Inventor: OHLROGGE KLAUS
IPC: B01D53/22
Filed: 1992-04-27
Abstract: The proposal is for a process and device (10) for separating gas mixtures (12) formed above liquids (11), especially hydrocarbon gas mixtures, using separating device (13) having a gas separation diaphragm, on the retentate side (14) of which can be produced a mixture (retentate) from which one or more components have been removed and on the permeate side (15) of which can be produced a mixture (permeate) enriched with one or more components. The volumetric quantity of the gas mixture (12) to be separated conveyed per unit of time to the separating device (13) by depression of the permeate and residue sides, which is produced during the transfer of the liquid (11) through its contact with the ambient gas (18), is greater than that of the liquid (11) transferred per unit of time during the transfer process. The volumetric quantity per unit of time of the permeate (15) thereby produced is thus the same as or smaller than that of the liquid (11) transferred during the process. Pumping devices (16, 17) are connected, on the retenttate side and on the permeate side, to the separating device (13) to produce a pressure range for the proper operation of the separaint device (13) to produce a pressure record for the proper operation of the separating device (13) and to convey the gas mixture (12) to the separating device (13).
