    Abstract: A process for producing ammonia synthesis gas from a hydrocarbon-containing feedstock, with steps of primary reforming, secondary reforming with an oxidant stream, and further treatment of the synthesis gas including shift, removal of carbon dioxide and methanation, wherein the synthesis gas delivered by secondary reforming is subject to a medium-temperature shift (MTS) at a temperature between 200 and 350° C., and primary reforming is operated with a steam-to-carbon ratio lower than 2. A corresponding method for revamping an ammonia plant is disclosed, where an existing HTS reactor is modified to operate at medium temperature, or replaced with a new MTS reactor, and the steam-to-carbon ratio in the primary reformer is lowered to a value in the range 1-5?2, thus reducing inert steam in the flow rate trough the equipments of the front-end.

  • Patent number: 10023804
    Abstract: A system and method of converting tires or other solid carbon based material is disclosed, including providing a chamber, feeding the solid carbon based material into the chamber, rotating the chamber, heating and reducing the material in the chamber, collecting solid residue from the chamber, collecting vapor from the chamber, and converting vapor collected from the chamber to a liquid. In an embodiment, the material includes a whole tire. The tire is heated in the chamber causing the tire to collapse and liquefy, exposing the metal in the tire which aids in grinding the carbon material in the tire as it tumbles, collecting solid residue, for example tire carbons, and collecting vapor, for example vaporized oil, and benzene and methane gas from the chamber and converting the oil. The chamber may be heated to a temperature from about 350° F. to about 1100° F. using gases reclaimed from the material.

  • Patent number: 9994447
    Abstract: The present invention is a system and method of heating a reaction cell that produces hydrogen from a mixture of hydrocarbon fuel and steam. The reaction cell contains a first tube of hydrogen permeable material and a second tube of hydrogen impermeable material. The first tube and the second tube are concentrically positioned so that a gap space exists between the two tubes. A heat pipe structure is utilized to heat the gap space. The heat pipe structure defines an enclosed vapor chamber. A volume of a multi-phase material is disposed within the vapor chamber. The multi-phase material changes phase between a liquid and gas within an operating temperature range. A heating element is used to heat the vapor chamber to the operating temperature range. The vapor chamber transfers heat along its length in the same manner as a heat pipe.
