ABSTRACT:
A device for manufacturing a product gas containing hydrogen and carbon oxide from a feedgas mixture comprised substantiallty of hydrocarbon, includes a vessel partitioned by a tubesheet into an upper chamber and a lower chamber. Reformer tubes are mounted on and extend through the tubesheet from the upper chamber into the lower chamber. Each reformer tube is laterally enclosed over at least a portion of its axial length downwardly from the tubesheet by a jacket spaced outwardly therefrom forming an annular space extending along each said tube for establishing communication between the upper the lower chambers, allowing the product gas to be withdrawn from the upper chamber. The tubesheet forms a distribution chamber for directing the feedgas mixture into the reformer tubes. The tubesheet is formed of an inner hollow body mounted within an outer hollow body, with the two hollow bodies being in flow communication. Due to the arrangement of the hollow bodies forming the tubesheet and the jackets forming the annular spaces, the problem of reducing the pressure and temperature differences across the tubesheet is effected while maintaining good over-all performance of the reaction vessel.
