Study On Large Multitube Fixed Bed Oxidation Reactor

Chemical reactor is a extremely important equipment in process equipment. The multitube fixed bed oxidation reactor has been widely used in acrylic acid, maleic anhydride, phthalic anhydride and other basic organic chemical plant. Large-scale reactor device has great economic and social benefits for improving the capacity of scale production, reducing the unit energy consumption level and the manufacturing level of industrial equipment.This paper mainly researched the scale-up design of large multitube oxidation reactor in the acrylic acid reaction device. The subject carried on an analysis of the existing industrial device and catalyst characteristic, proposed to enlarge the design points and methods of large multitube fixed bed oxidation reactor. By the determine on main parameter, the subject put forward operable measures in the structure aspect, and analyzed the reactor channel for top inlet of tube side and circuit channel of shell side, verified the rationality of the structure through numerical simulation method.
