Abstract: The disclosure relates, inter alia, to a system comprising: (1) an electric power grid; (2) an electrolyzer generating a first stream of hydrogen in communications link with the electric power grid; (3) hydrogen production means for producing a second stream of hydrogen, said hydrogen production means being a non-electrolyzer in communications link with the electrolyzer; (4) a first conduit leading to a hydrogen user through which hydrogen flows to the hydrogen user; (5) a second conduit connecting the electrolyzer to the first conduit through which hydrogen from the electrolyzer flows to the first conduit at a first location; (6) a third conduit distinct from the second conduit connecting the non-electrolyzer to the first conduit through which hydrogen from the non-electrolyzer flows to the first conduit at a second location distinct from the first location; and (7) means for controlling and maintaining a continuous flow of hydrogen to the hydrogen user.

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hydrogen supplied from a storage cavern, particularly to removing methane and other hydrocarbons from the hydrogen withdrawn from the cavern by using selective adsorption.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.

Abstract: A top-fired reformer box is provided. The top-fired reformer box includes a burner row, a tube row, a reformer tunnel including a closed end, an open end, and a plurality of tunnel ports formed along a side wall of the reformer tunnel, the plurality of tunnel ports including a one or more tunnel port located along the side of the tunnel, and a flow resistor positioned at least one tunnel port applying a flow resistance for flue gas entering the reformer tunnel via the at least one tunnel port such that uniform flow is achieved within the reformer tunnel.

Abstract: Organic sulfur compounds contained in refinery off gas streams having either high or low concentrations of olefins are converted to hydrogen sulfides which can be then be removed using conventional amine treating systems. The process uses a catalytic reactor with or without a hydrotreater depending on the olefin concentration of the off gas stream. The catalytic reactor operates in a hydrogenation mode or an oxidation mode to convert a majority of organic sulfur compounds into hydrogen sulfides.

Abstract: The present invention is directed to a method and system of separating carbon monoxide from syngas mixtures with high methane content by cryogenic means where a partial condensation cycle is generally employed, and more specifically towards combining the methane-rich liquid exiting the distillation column with a lower-boiling mixture so that the boiling point of the combined stream is lower than the boiling point of the methane-rich liquid.

Abstract: The present invention relates to integrating a hot oxygen burner with an auto thermal reformer of reducing in a system for generating synthesis gas.

Abstract: The present invention provides a method and apparatus for separating air and generating electrical power. A compressed air stream produced in a main air compressor is introduced into an air separation unit that cryogenically rectifies the air into component products. During turndown conditions of the air separation unit, a combustion air stream formed from all or part of the compressed air stream is introduced into a combustor in which a fuel is combusted to produce a heated and pressurized combustion stream. Such stream is introduced to a turbine connected to an electrical generator to generate electrical power. The combustion air stream can be saturated with moisture to increase power output. Further, the combustion air stream can also be preheated with an exhaust of a gas turbine.
