Description

technical field [0001] The invention relates to a method for manufacturing a steel structure, in particular to a method for manufacturing a steel structure frame of a benzene hydrogenation main device in a benzene hydrogenation project. Background technique [0002] The process of benzene hydrogenation unit is quite special, its system is complicated, there are many equipments, the pressure and temperature of the system itself are high, and the pump equipment is not allowed to run idle. The benzene hydrogenation project is mainly divided into the central control room and substation, refining device, water supply and drainage project, air compressor station, storage and transportation facilities (tank farm and pump room), power supply for the whole plant and lighting for the whole plant, torches and ancillary projects There are special requirements for lightning protection, fire protection and explosion protection in the installation of these facilities. Among them, the steel...
