AspenTech, a US supplier of software and services to the process industries, recently announced it has been awarded a contract to supply a series of operator training simulators for the US$4.3 billion Nanhai Petrochemicals Project of CNOOC-Shell Petrochemical Company (CSPC) at Daya Bay in Huizhou City in South China's Guangdong Province. Under the contract, AspenTech will develop seven sets of Virtual Plant Simulators (VPS) for all key units in the petrochemical complex, including olefins, pygas, butadiene, styrene, monomer, propylene oxide, ethyl benzene and ethylene oxide. The simulators use modeling software to provide a comprehensive dynamic model of the facilities that accurately mirrors the behavior of the plant. The VPS models will be used for operator training before start-up and then for refresher training and operations improvement. The use of simulators will help ensure the safe and efficient renning of the new plants, by enabling operators to experience a full range of operating scenarios before the plant is put into commissioning.
