Patent number: 11850553Abstract: A system and method of pre-purification of a feed gas stream is provided that is particularly suitable for pre-purification of a feed air stream in cryogenic air separation unit. The disclosed pre-purification systems and methods are configured to remove substantially all of the hydrogen, carbon monoxide, water, and carbon dioxide impurities from a feed air stream and is particularly suitable for use in a high purity or ultra-high purity nitrogen plant. The pre-purification systems and methods preferably employ two or more separate layers of hopcalite catalyst with the successive layers of the hopcalite separated by a zeolite adsorbent layer that removes water and carbon dioxide produced in the hopcalite layers. Alternatively, the pre-purification systems and methods employ a hopcalite catalyst layer and a noble metal catalyst layer separated by a zeolite adsorbent layer that removes water and carbon dioxide produced in the hopcalite layer.Type: GrantFiled: January 29, 2021Date of Patent: December 26, 2023Assignee: PRAXAIR TECHNOLOGY, INC.Inventors: Ralph J. Mancini, Cem E. Celik, Matthias Grahl, Arthur C. Selover, Sesha Hari Vemuri, Helko Schneider

Patent number: 10668426Abstract: A process for producing an adsorption unit is disclosed, wherein an adsorber bed of the adsorption unit is filled with a bed of an adsorbent which is selected from a multitude of adsorbents by a test method, wherein, in the test method, a particle of each adsorbent is repeatedly laden with a sorbate and regenerated again, which converts the particle to an aged particle, and a fracture property B of the aged particle of each adsorbent is determined, wherein the adsorbent for the bed is selected depending on the fracture property B determined from the multitude of adsorbents.Type: GrantFiled: November 7, 2017Date of Patent: June 2, 2020Assignee: LINDE AKTIENGESELLSCHAFTInventors: Matthias Grahl, Christian Voss, Helko Schneider, Philipp Keil

Publication number: 20180126319Abstract: The method serves for producing a horizontal through flow adsorber with two adsorbents which contains two immediately adjacent packings in a horizontal or vertical container. Between the two packings there is a vertical interface. In a step (a) a vertical dividing wall is positioned on the bottom of the adsorption bed and then on each side of the dividing wall one of the two adsorbents is charged up to a first height that does not exceed the upper edge of the separating ring. In the following step (b) the vertical dividing wall is displaced upwardly until the lower edge thereof is still placed in the existing packing. Then, on each side of the dividing wall one of the two adsorbents is charged up to a second height that does not exceed the upper edge of the displaced dividing wall. Finally, step (b) is repeated until a predetermined filling height is achieved. According to the invention, the vertical dividing wall is composed of at least three dividing wall modules (6.Type: ApplicationFiled: January 26, 2016Publication date: May 10, 2018Inventors: Johann FERSTL, Matthias GRAHL, Wolfgang BADER, Helko SCHNEIDER, Philipp KEIL, Michael FIRLBECK, Harald HENTSCHEL
