According to the related standard, has carried on the design of the plate column for a given parameter. After calculation and the main size of the tower equipment is determined ,which meet the technological requirements of the tower.The wind load, and the earthquake load of some dangerous sections have also been checked.Moreover, the strength check and the stability check of the dangerous sections have been on strictly and the connection pattern of the corresponding parts have also been determined.During the mechanical design phase,the anchor bolts,the base ring, ribs,cover plate and trays, etc, and the determination the connection pattern of the corresponding parts. The plate tower involved in the paper meet the requirements of a given process condition. In addition, according to the reinforcement of holes and principles of material selection, etc., the reinforcement design,and opening reinforcement and principles of material selection, etc., and the water pressure test and the requirement of shell strength checking, equipment manufacturing, testing design points are introduced in detail, providing a certain reference for design of the same kind of product experience. The main advantages of the de-heavy fractionator is: the de-heavy fractionator through take off his excess a restructuring in the material, extract high purity materials, and low energy consumption, high efficiency.
