Abstract: The invention relates to a process and an apparatus for cooling a flue gas stream from a reformer furnace of a steam reformer for steam reforming a hydrocarbon containing feed stream with a reforming steam stream to produce a crude synthesis gas stream. According to the invention, the flue gases are cooled by heat exchange with air in a combustion air preheater which comprises at least two separate heat exchange zones, and the temperature of the flue gas stream passing the separate heat exchange zones decreases stepwise in flow direction of the flue gas stream.

Abstract: A feedstock gas reactor includes a reaction chamber and a first regenerative heat exchanger. A feedstock gas is flowed into the reaction chamber via the first regenerative heat exchanger. The feedstock gas is decomposed in the reaction chamber so as to produce reaction products. The reaction products are flowed out of the reaction chamber. The feedstock gas reactor may also include a second regenerative heat exchanger, and the reaction products may be flowed out of the reaction chamber via the second regenerative heat exchanger. Heat from the reaction products may stored in the second regenerative heat exchanger as the reaction products flow through the second regenerative heat exchanger, for later transfer to a feedstock gas flowing into the reaction chamber via the second regenerative heat exchanger.

Abstract: When a product gas producing operation is stopped, a purge operation is executed in which steam purge processing and product gas purge processing are sequentially performed. The steam purge is supplying, instead of a source gas, a product gas from a product gas tank to a reformer using a compressor, and supplying a reformed gas from a reforming processing unit to a plurality of adsorption towers, which perform a pressure swing adsorption operation, while the reformer is heated by a heating burner and steam is supplied to the reformer. The product gas purge is supplying the product gas from the product gas tank to the reformer using the compressor, and supplying the product gas from the reforming processing unit to the plurality of adsorption towers, which perform the pressure swing adsorption operation, while the supply of the steam is stopped and the heating of the reformer is maintained.

Abstract: The disclosed technology provides processes for producing hydrogen that is renewable, has negative carbon intensity, and is associated with net water production. The hydrogen is economically, environmentally, and socially superior to conventional hydrogen via steam reforming of natural gas or electrolysis of water. Some variations provide a process for manufacturing carbon-negative hydrogen and optionally activated carbon, comprising: feeding biomass into a first heated vessel or zone to generate dried biomass and a first recovered water stream; feeding the dried biomass into a second heated vessel or zone to pyrolyze the dried biomass, generating a biocatalyst and a biogas; feeding the biocatalyst, the first recovered water stream, and biogas to a third heated vessel or zone for biocatalytic conversion, thereby generating H2, CO, and optionally activated carbon; and recovering the hydrogen. The H2 is carbon-negative hydrogen characterized by a carbon intensity less than 0 kg CO2e per metric ton H2.

Abstract: Methods and systems are disclosed that monitor the carbon and hydrogen production of a pyrolysis reactor system and adjust one or more inputs to the reactor system to improve performance when one or both of the monitored carbon and hydrogen production falls outside of a target performance specification. In particular, the ratio of fuel to oxidant (“fuel/oxidant ratio”) supplied to a combustion chamber of the reactor system is adjusted to below a fuel/oxidant equivalence ratio range, defined as 0.9-1.1, when both carbon and hydrogen production falls below a target carbon and hydrogen specification, and adjusted above the fuel/oxidant equivalence ratio range when only the carbon production falls below a target carbon specification. The target specification can include a number of parameters including production rate, morphology (of carbon), and operating temperature.

Abstract: Processes for cracking ammonia are improved by using heat generated in a compression unit that is used to compress PSA off gas being recycled to a PSA unit to pre-heat liquid ammonia prior to vaporization and cracking. The heat is transferred using a heat transfer fluid such as an aqueous solution comprising from about 50 wt. % to about 60 wt. % of a glycol, e.g., ethylene glycol or propylene glycol.

Abstract: A process for producing a carbon dioxide depleted synthesis gas product by steam reforming is provided. The process includes cooling crude synthesis gas stream produced in a main reforming stage in a first cooling device and reacting in a carbon dioxide absorption column, reacting a carbon dioxide loaded absorbent stream from the carbon dioxide absorption column in an absorbent regeneration column, cooling the carbon dioxide enriched hot vapor stream from the absorbent regeneration column in a second cooling device and cooling a carbon dioxide depleted hot absorbent stream from the absorbent regeneration column in a third cooling device. Preheated air streams from the cooling devices are fed as oxidant to the main reforming stage.
