On December 22, 2023, the first pressure reducing tower of the 3 slurry bed residue hydrogenation unit of the second phase of the project department of Zhejiang Petrochemical was successfully hoisted, marking the official start of the hoisting of the core equipment of the 3 slurry bed.
C-3003B pressure reducing tower, with a net height of 62 meters, a maximum diameter of 9 meters, a net weight of 623 tons and a lifting weight of 843 tons, is the first of the "three instruments and two towers" of the 33 million tons of slurry bed residue hydrogenation unit, and is also one of the core equipment of the slurry bed unit.
As of December 22, the preparations for the hoisting were ready, the technical and safety personnel were on site and the whole process was commanded, and the hoisting work of the depressurized tower officially began at 10:10 a.m. The hoisting used a 3600-ton crawler crane main crane and a 2000-ton crawler tail crane, which lasted 2 hours to successfully lift the decompression tower onto the reactor frame. As planned, the hoisting of the second C-3003A depressurization tower was carried out one day later.
The successful hoisting of the pressure reducing tower marks a new stage in the on-site construction of the slurry bed unit of the second phase of the Zhejiang Petrochemical Project.
