Patents by Inventor Matthias Wessling

Matthias Wessling has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Gas separation membrane module and process
    Patent number: 5711882
    Abstract: A spiral-wound, gas-separation membrane module and a gas-separation process. The module and process provide at least partial counter-current flow between the feed and permeate gas streams without requiring a permeate sweep. The counter-current flow pattern can be achieved by appropriate placement of barriers or baffles in the feed channel. Similar modules and processes may also be used for pervaporation.

  • Vapor recovery process using baffled membrane module
    Patent number: 5611841
    Abstract: A gas-separation method for controlling vapor emissions. The method employs a spiral-wound membrane module, adapted to provide one or more feed-side baffles in the feed channel. The method may be used to control vapor emissions from a volatile liquid, and is particularly useful to control fuel vapors emitted during fuel transfer operations.
