Abstract: A solid-gas reaction substance-filled reactor includes a core part in which heat medium heat-transfer tubes and spacers are alternately stacked, a gas introduction/discharge part that communicates with opening ends of the spacers, and a heat medium introduction/discharge part that communicates with heat medium flow paths. Filled bodies including metallic foil bags and a solid-gas reaction substance filled in the bags are inserted into the spacers. At least the filled bodies and the heat medium heat-transfer tubes are brazed to each other. The solid-gas reaction substance-filled reactor is obtained by stacking the filled bodies with the solid-gas reaction substance filled into the metallic bags, the heat medium heat-transfer tubes, and the spacers in a predetermined order and then brazing them.

Abstract: Disclosed is a technology based upon the nesting of tubes to provide chemical reactors or chemical reactors with built in heat exchanger. As a chemical reactor, the technology provides the ability to manage the temperature within a process flow for improved performance, control the location of reactions for corrosion control, or implement multiple process steps within the same piece of equipment. As a chemical reactor with built in heat exchanger, the technology can provide large surface areas per unit volume and large heat transfer coefficients. The technology can recover the thermal energy from the product flow to heat the reactant flow to the reactant temperature, significantly reducing the energy needs for accomplishment of a process.

Abstract: A multi-tubular chemical reactor (400) includes an igniter (435) for the initiation of gas phase exothermic reaction within the gas phase reaction zones (409) of the tubular reactor units (408). A method of carrying out a gas phase exothermic reaction within the multi-tubular chemical reactor comprising: introducing gaseous reactants into a tubular reactor unit (408); initiating with radiant heat an exothermic reaction of the gaseous reactants within the reactor unit; and transferring heat produced by the exothermic reaction occurring within the gas phase reaction zone of the reactor unit to the gas phase reaction zone of one or more adjacent reactor units (408), thereby initiating an exothermic reaction within at least one adjacent reactor unit (408) until in such manner an exothermic reaction has been initiated in each of the plurality of spaced-apart reactor units (408).

Abstract: The invention relates to a process and a plant for the methanol synthesis, in particular for the methanol synthesis from a synthesis gas which has a hydrogen deficiency. According to the invention, a purge gas stream therefor is branched off from the synthesis gas circuit of the methanol synthesis, liberated from methanol traces in a washing device, and then treated in a hydrogen separation device which comprises a membrane separation stage and a pressure swing adsorption stage. Depending on the application and magnitude of the hydrogen deficit the membrane separation stage and the pressure swing adsorption stage can be connected in series or in parallel.
