Using mainly high sulfur crude oil from the Kazakhstan-China pipeline, the complex processes 10 million tons of crude oil and produces 1 million tons of ethylene per year. As such it plays an important role in the China-Kazakhstan energy cooperation strategy. The utility plant that provides steam, electricity, and water to this complex include five 440 t/h circulating fluidized bed (CFB) boilers, three 100 MW turbines/ generators, and chemical and water treatment systems. The complex’s CFB boilers use brown coal as a fuel and are designed to keep CO2 emissions to a minimum. Normally, four of the complex’s five boilers are in use and the remaining boiler is kept on standby and undergoes maintenance.For the utility plant at this important industrial complex, Yokogawa China successfully installed a CENTUM CS 3000 integrated production control system and the Plant Resource Manager (PRM) package.Yokogawa’s CENTUM CS 3000 and PRM in Utility Plant of Dushanzi Refinery & Petrochemical ComplexPlant InformationPlant name: Utility plant for Refinery and Petrochemical plantsLocation: Dushanzi, Xinjian Urghur Autonomous Region, ChinaProject type: NewPlant type: Circulating fluidized bed boilerOutput: 3x 100MWOrder date: June 2006Completion: January 2010RefineryPetrochemical plantThe PetroChina Dushanzi head office
