    Abstract: High purity hydrogen is produced by a steam reforming hydrogen production unit with at least one of a bayonet reactor for reforming steam and a hydrocarbon, a recuperative burner, and a regenerative burner such that the steam reforming unit produces little or no steam in excess of the steam reforming process requirements. High purity hydrogen is separated from the syngas exiting the reformer via a pressure swing adsorption unit and combined with high purity nitrogen from an air separation unit as feedstock to a Haber process ammonia synthesis unit. Compressors for the ammonia synthesis unit are driven by higher efficiency drivers than are possible using the low temperature steam conventionally exported from a steam reforming unit. Compression power requirements are reduced.

    Abstract: A bayonet reactor including a catalytic reactor in the form of an annular structured packing is provided with increased surface area for the transfer of heat between annulus gas and return gas, an increased coefficient of heat transfer between the annulus and return gases, and a reduced overall pressure drop relative to conventional reactors. The reactors of the present technology can enable intensified catalytic processing.

    Abstract: A support structure for a structured catalytic packing is disclosed. The support structure is in a fixed position relative to the reactor tube containing it. It supports catalyzed casings that are free to move relative to the support structure. The support structure and casings are inserted in the reactor tube such that the support structure is located proximate the longitudinal axis of the tube and the casings are located between the support structure and the reactor tube wall. The support structure comprises a central support tube or rod proximate to, and impervious or perforated discs perpendicular to, the longitudinal axis of the reactor tube, and may comprise spacers separating the discs.

    Abstract: An apparatus includes an inlet, an outlet, and a sheet disposed proximate a heat transfer surface, wherein the sheet is oriented in a sheet plane that is displaced from a plane of the heat transfer surface by an angle of at least 10 degrees. The apparatus also includes a plurality of tabs attached to the sheet, the tabs lying in respective tab planes, wherein the tab planes and the sheet plane intersect forming respective intersections. The intersections of the tab planes and the sheet plane are substantially parallel. The intersections of the tab planes and the sheet plane are at an angle of less than 88° to the heat transfer surface, and the plurality of tabs collectively form channels directing a fluid passing from the inlet to the outlet to impinge the heat transfer surface.

    Abstract: Steam reforming processes can include treatment of syngas by water gas shift, water separation, and hydrogen separation by pressure swing adsorption (PSA). Additionally, CO2 can be scrubbed from the syngas prior to the PSA. PSA tail gas, including CH4, CO, and H2, can be recompressed and recycled to the PSA for further hydrogen separation and to the steam reformer feed to convert eventually all carbon in the feedstock into CO2 for the scrubber to separate. Fuel requirements can be fulfilled by part of the hydrogen product to eliminate stack CO2 emissions. The hydrogen used as fuel is heated and turbo-expanded to provide power before being combusted as fuel. A nitrogen purge may be added.
