Yanshan Petrochemical Group, the largest petrochemical enterprise in China, has chosen Emerson Process Management’s PlantWeb field-based architecture with FOUNDATION fieldbus to automate benzene processing in its ethylene plant in Beijing. As a leader in its field, Yanshan Petrochemical constantly looks for ways to improve its production capabilities. For this major project at their ethylene plant, the advantages of the field-based approach with FOUNDATION fieldbus technology were compelling. “We plan to expand our ethylene production capacity from 450,000 tons to 710,000 tons per year,” explained project manager Qiao Xian Yi. “We need an advanced and reliable technology to support this expansion, so we chose FOUNDATION fieldbus.” Fieldbus instrumentation for the project includes includes Rosemount pressure and temperature transmitters and vortex flowmeters, Fisher Controls valves with FIELDVUE(R) digital valve controllers, and a DeltaV(TM) automation system with integrated Asset Management Solutions (AMS) software. HART-based Micro Motion flowmeters are also integrated into the architecture. Total input/output is 1000 points.
