【Ten Years of Rapid Development in Chemical Engineering Equipment】Modular installation of 3 million tons/year slurry-bed residue hydrogenation reactor frameworks from 1273 to 2023

Thread Content

The reactor frame of Zhejiang Petrochemical’s No. 3 3-million-ton/year slurry-bed residue hydrogenation unit is 48 meters long, 33 meters wide, and 125 meters high; it has 4 axes in the east-west direction and 5 axes in the north-south direction. The total weight of the steel structure is 5,600 tons. There are 8 modules in total, and this unit constitutes the core part of the No. 3 slurry-bed residue hydrogenation facility; it is also one of the largest reactor frames among domestic refining and petrochemical plants in terms of scale. On November 28, 2023, the reactor frame of Zhejiang Petrochemical’s No. 3 3-million-ton/year slurry-bed residue hydrogenation unit was successfully capped. A 2,000-ton class large crawler crane slowly lifted the final module to the top of the reactor frame; after one hour of lifting and module assembly, it was in place. The successful completion of the reactor frame construction for this facility marks the achievement of another key milestone in the construction of Zhejiang Petrochemical’s Phase II project, representing a partial success. It also signals the start of intensive work on the installation of Reactor No. 3 of the slurry bed type.
