Construction of a large company overhaul the scientific project management project organization, major overhaul and installation, Qing coke, the shelter team struggled hard to work hard, Sinochem Quanzhou Petrochemical 3.4 million tons / year catalytic cracking unit bulky 'two' in 1 Closed on January 7 manhole closed.
Overhaul of the "two-piece" facilities is the key line of the FCC unit. It is divided into three parts: one is a settler with a height of 79 meters and a maximum diameter of 9.6 meters, On the end of a layer of hard coke, the removal of large amount of extremely difficult, there is the danger of flammable poisoning, coking construction difficult and dangerous.Second is the height of 66 meters, the maximum diameter of 14.3 meters regenerator, which to be cyclone, A large hole sub-board more than a dozen maintenance, scaffolding erection of large, flour-like catalyst dust have risen, with a dust mask can also feel pungent choking odor, the environment is relatively harsh. , Each heat collector to cut and remove some of the steel frame platform, disassemble sixty or seventy connecting pipe flange, and then hoist about 70 tons of tube bundle, check the repair and then lifting reset, pipe-intensive flange disassembly difficult , Heavy lifting tube bundle difficult.
"Two" overhaul is the most important, ten companies attach great importance to this, seriously plan the careful planning, deployment of experienced quality good installation, focus on the professional team for overhaul, good ventilation to maintain 'two' Air circulation is good, full of red scaffolding and hard isolation platform are set up in the regenerator. No co-firing work is allowed in the coke cleaning stage in the settler. 35 installers, 50 defocused workers and 30 child workers work strictly in accordance with safety standards. Organize the command, safety, technical quality, guardianship and strict devotion to their duties.
