  • Patent number: 11571652
    Abstract: The present invention is directed to a method and system of purifying hydrogen supplied from a storage cavern, particularly to removing methane and other hydrocarbons from the hydrogen withdrawn from the cavern by using selective adsorption. The adsorbed impurities can be removed from the adsorbent by increasing the temperature, reducing the pressure, or a combination of both.
    Type: Grant

  • Patent number: 9365422
    Abstract: A method and system for producing a synthesis gas in an oxygen transport membrane based reforming system that utilizes a combined feed stream having a steam to carbon ratio between about 1.6 and 3.0 and a temperature between about 500° C. and 750° C. The combined feed stream is comprised a pre-reformed hydrocarbon feed, superheated steam, and a reaction product stream created by the reaction of a hydrogen containing stream reacted with the permeated oxygen at the permeate side of the oxygen transport membrane elements and wherein the hydrogen containing stream is a recycled portion of the synthesis gas.

  • Publication number: 20090254950
    Abstract: According to one embodiment, a method is described. The method includes receiving a request at a control module from a first remote device to access media data from a storage management module and determining that a first user is requesting access to the data based upon a first remote identification (ID). The method further includes opening a second stream between the playback module and the storage management module and receiving the data at the playback module.

  • Publication number: 20070220580
    Abstract: A user interface for a media convergence platform is disclosed. The television based user interface presents different types of media within a single user interface. The user interface displays, on a television display, selectable items to represent a music application, a photo albums application, a video application, and an Internet content application. The user selects an item displayed on the television display to invoke an application. The music application permits a user to select music available within the media convergence platform, and to playback the music through a device in the media convergence platform. The photo albums application permits a user to select one or more photos available within the media convergence platform, and to view the photos through a device in the media convergence platform.
