  • Publication number: 20230331549
    Abstract: A process for producing syngas that uses the syngas product from a partial oxidation reactor to provide all necessary heating duties, which eliminates the need for a fired heater. Soot is removed from the syngas using a dry filter to avoid a wet scrubber quenching the syngas stream and wasting the high-quality heat. Without the flue gas stream leaving a fired heater, all of the carbon dioxide produced by the reforming process is concentrated in the high-pressure syngas stream, allowing essentially complete carbon dioxide capture.

  • Patent number: 7506822
    Abstract: Disclosed herein are injectors and methods for use thereof. In one embodiment the injector comprises: an inner tip, a slurry tip disposed around the inner tip forming a second flow channel, and a wear insert disposed within the slurry tip and in contact with the second flow channel. The inner tip comprises a first flow channel attached to a first supply conduit that can supply a first media to the first flow channel. Attached to the slurry tip is a second supply conduit, which can supply a second media to the second flow channel. The wear insert comprises a metal oxide.
