Patent number: 4578089Abstract: Pressure swing adsorption with increased recovery of a highly adsorbable product gas component is carried out with a cycling in which, during the flushing phase, and at least over the latter portion thereof, the flushing gas has a concentration in the product gas component which is substantially equal to that of the product gas. To further increase the yield and the concentration of the product gas component in the product gas, the pressure in the absorber is reduced over a time period between the termination of the adsorption phase and the beginning of the desorption phase, with the effluent gas during this reduction in pressure being reused in the pressure swing adsorption cycle.Type: GrantFiled: December 14, 1984Date of Patent: March 25, 1986Assignee: Bergwerksverband GmbHInventors: Ekkehard Richter, Werner Korbacher, Karl Knoblauch, Klaus Giessler, Klaus-Burkhard Harder

Patent number: 4566881Abstract: A process of and apparatus for producing oxygen with a low fraction of argon from a gaseous medium like air, in which a gaseous medium is introduced into a first adsorption unit to produce an intermediate gas enriched with oxygen and depleted of argon. The intermediate gas is then supplied to a second adsorption unit in which the final product gas is prepared as well as a by-product which is returned into the process. Each of the adsorption units includes at least two adsorbers operating in a working cycle wherein the working cycle of the adsorbers of the second unit lasts about twice as long as the working cycle of the adsorbers of the first unit. For allowing an evacuation of each adsorber and thus a regeneration thereof, a common vacuum pump is connected to each unit in such a manner that the regeneration of the adsorbers of the second unit is temporarily interrupted when one of the adsorbers of the first unit is evacuated.Type: GrantFiled: January 28, 1985Date of Patent: January 28, 1986Assignee: Bergwerksverband GmbHInventors: Ekkehard Richter, Karl Knoblauch, Rolf Schlegel, Werner Korbacher

Patent number: 4521221Abstract: A pressure-swing adsorption system is used to enrich the methane content of mine gas obtained from bores around mine shafts or galleries from the customary 25 to 45% by volume to a product gas quality of 50% by volume. Using a carbon molecular sieve adsorbent, the adsorption is carried out at 5 to 8 bar and is followed by a uniflow expansion to an intermediate pressure and a counterflow expansion to a flushing pressure of 1.1 to 2 bar. Counterflow flushing is carried out with waste gas and the product gas is a mixture of the gases obtained by counterflow expansion and flushing.Type: GrantFiled: February 22, 1984Date of Patent: June 4, 1985Assignee: Bergwerksverband GmbHInventors: Ekkehard Richter, Werner Korbacher, Karl Knoblauch, Klaus Giessler

Patent number: 4406674Abstract: Method for separating gas mixtures resulting from direct flow loading of adsorption reactors by means of a pressure change technique in a two stage adsorption reactor consisting of a prefilter and a separating filter, whereby strongly adsorbable impurities from the gas mixture are adsorbed in the prefilter and the remainder of the undesirable gas components are adsorbed in the separating reactor. Thereby, product gas flows off at the end of the separating reactor shortly before the passage therethrough of a non-desirable gas component. Thereafter, the prefilter and the separating reactor are disconnected and the prefilter is partially relieved by a gas counter flow and the separating reactor is partially relieved by direct gas flow. After reconnection of prefilter and separating reactor the unit is further released in the counter current, subsequently rinsed and is again brought to charge pressure in the direct or counter current.Type: GrantFiled: June 1, 1982Date of Patent: September 27, 1983Assignee: Bergwerksverband GmbHInventors: Karl Knoblauch, Ekkehard Richter, Klaus Giessler, Werner Korbacher
