AI Technical Summary
Existing catalytic heat exchange reactors suffer from problems such as uneven heat transfer and high material costs, especially in primary reforming processes where it is difficult to effectively utilize waste heat for additional reforming.
Design a catalytic heat exchange reactor with helical flow on the shell side of the heat transfer tubes. Employ a single-tube design, stepped baffles, and a Z-shaped tube pattern, combined with a central mixing gas tube, to ensure uniform heat transfer to all heat transfer tubes and reduce material usage.
This resulted in a more compact reactor design, reduced production costs, improved heat exchange uniformity and efficiency, reduced need for external return flow lines, and simplified manufacturing and installation processes.
