In the careful construction of ten companies carefully coordinated, after careful preparations for the previous ten to build a responsible for overhaul of the Sinochem Quanzhou 12 million tons / year oil refinery project core device - 3.4 million tons / year FCCU technical upgrading of the war, At 8 o'clock on December 14 across the board started.
The unit, originally constructed by Ten Construction Company, was completed and put into production in April 2014 and has been operating continuously for 3 years and 7 months. It was stopped for the first major overhaul in early December. It is a major overhaul of the 12 million tons / year refinery project The weight of the entire plant overhaul technical transformation of the two main lines are in this device: one is 80 meters high reactor, regenerator, three-rotating system overhaul, and the other is the device faucet two waste heat boiler technological transformation; In addition Ten also assumed the installation of seven towers, 76 heat exchangers, 26 containers, 5 filters, 217 valves, 58 leaks sealed, 292 blind disassembly, 13000-inch diameter pipe installation and other overhaul Technical transformation tasks, due to the long-term operation of the device, the volume of large and intensive, large amount of maintenance work, the construction period of only 28 days, so overhaul the technical transformation of construction organizations, safety management is very difficult.
Ten construction attaches great importance to this major overhaul technical transformation, early preparation of 3.4 million tons / year catalytic cracking unit 2017 overhaul project planning book, detailed preparation of overhaul of technical transformation and construction plans and manpower mechanical needs planning, pumping installation and overhaul of catalytic cracking A total of more than 400 professional engineers and construction teams with rich experience in overhaul have mobilized more than 400 sets of 25 lifting transport machinery, core pulling machines and electric welding machines to participate in the war.
