China Drying News reported that at the time of January 10, at 10:35, with the order of Zhang Laimin, Chief Engineer of the Shaanxi Provincial Yanchang Huajian Engineering Co., Ltd., the site's general hoisting commander, the company weighed 267 tons of residue catalytic cracking (DCC) ethylene. The device reactor head was slowly lifted and installed in place 20 minutes later, marking the successful installation of the largest DCC reactor in the country.
The DCC reactor is the key equipment for extending the 1.5 million t/y DCC ethylene unit in China Coal Jingbian Energy and Chemical Project. The reactor has a top elevation of 72.7 meters, a maximum diameter of 13.6 meters, a weight of 919.51 tons, and a weld length of 1275 meters. At the same time, DCC regenerators with a top elevation of 58.7 meters, a maximum diameter of 15.4 meters, and a weight of 1,442.01 tons were also installed. The installation of two very large core equipments successfully marked the installation of the major DCC devices in the country.
Extend the total investment of the Jingbian Jingbian Energy Chemical Project by 27.1 billion yuan. The first-phase construction scale will be an annual output of 1.8 million tons of methanol, 1.5 million tons of DCC ethylene, 600,000 tons of MTO, 600,000 tons of polypropylene and 600,000 tons of polyethylene. Other chemical products. The 1.5 million-ton/year DCC unit is one of the seven core units of the Jingbian Nenghua Project. It uses the catalytic cracking process jointly developed by the China Petroleum and Chemical Research Institute and China Petrochemical Engineering Construction Co., Ltd., from the Sinopec Engineering Construction Company (SEI) EPC. General contractor, Shaanxi Yanhua Engineering Co., Ltd. is responsible for construction and installation.
