  • Recovery of gases, especially permanent gases, from streams of matter, especially from offgas streams from polymerizations
    Patent number: 10092876
    Abstract: A method of cleaning a stream of matter that includes a C2+ fraction and a first gaseous substance and a second gaseous substance. The stream of matter is subjected to a pressure swing adsorption to remove the C2+ fraction by means of a membrane to obtain a retentate and a permeate. The first substance is enriched in retentate and depleted in permeate and the second substance is depleted in retentate and enriched in permeate.
    Type: Grant
    Filed: July 23, 2015
    Date of Patent: October 9, 2018
    Assignee: Linde Aktiengesellschaft
    Inventors: Volker Witzleb, Werner Leitmayr, Christian Voss, Akos Tota, Martin Bauer

  • POLYMERIZATION SYSTEM HAVING A REGENERATION DEVICE FOR AN ADSORPTIVE AND/OR CATALYTIC CLEANING DEVICE, REGENERATION DEVICE, AND REGENERATION METHOD
    Publication number: 20160236173
    Abstract: A polymerisation system for obtaining at least one polymerisation product from at least one gaseous, hydrocarbon-rich feed stream, which system has at least one catalytic and/or adsorptive cleaning device for the at least partial extraction of at least one undesirable component in the at least one feed stream and a regeneration device for the regeneration of the cleaning device. The regeneration device is designed to at least intermittently condition and conduct a regeneration gas stream through the cleaning device by means of a partially closed gas circuit. There is further provided a corresponding regeneration method.
