    摘要: A communications unit. At least one example includes a platform that has a tower assembly operably coupled thereto such that tower assembly is movable between a horizontally deployed position and a vertically deployed position relative to the platform. The tower assembly includes a plurality of telescoping tower segments that are movably supported relative to each other such that they may be selectively manually deployed between a retracted position and the horizontally deployed position. The unit may further include a locking assembly that is configured to selectively and individually lock each of the plurality of telescoping tower segments in the horizontally deployed position. A deployment assembly operably interfaces with the tower assembly and is configured to selectively move the tower assembly between the horizontally deployed position and the vertically deployed position.

    摘要: The present invention is a natural gas steam reforming method for generating an output gas mixture of carbon dioxide and hydrogen, including the following steps. (1) Combusting a portion of the natural gas with an oxidizing agent to generate heat, superheated steam, and a gas mixture of carbon dioxide, carbon monoxide, and hydrogen. (2) Steam reforming the gas mixture with additional superheated steam under steam-rich conditions to transform a remaining portion of the natural gas into carbon dioxide, carbon monoxide, and hydrogen. (3) Water-gas-shifting any residual carbon monoxide into additional carbon dioxide and additional hydrogen by utilizing a water-gas-shift catalyst downstream of the steam reforming step, thereby producing an effluent gas mixture that is predominantly carbon dioxide and hydrogen. (4) Boiling water in a top-to-bottom linear countercurrent heat exchanger to generate the superheated steam by transferring heat released in the water-gas-shifting step, where as the water is gravitationally and thermally stratified from top to bottom with a top portion boiling into steam, the steam continues to rise and is additionally heated in the top-to-bottom linear countercurrent heat exchanger. (5) And, utilizing the superheated steam produced as a reactant in the steam reforming step and the water-gas-shifting step to assist in reformation of the natural gas into carbon dioxide and hydrogen.
