Image Number 2 for United States Patent #4046630.
To supply process heat to a number of discrete reaction zones typically of a methane reformer plant, the hot gas from a nuclear reactor is employed. The reaction zones are defined within the bores of process tubes and heat is applied by way of gas conduits co-axial with the tubes. The reactants and heating gas are passed in counter current from header pipes which are coupled to the process tubes by flexible pipes. The latter are crushable to isolate any particular process tube, eg for replacement of catalysts etc.
