Chinese refiner Sinopec has deployed Siemens’ new Analyzer System Manager (ASM) at its Shanghai production site. The new software is now controlling measurement quality from around 60 of the refiner’s analyzers, and recording data quality trends. Siemens developed, engineered and commissioned the ASM system. Sinopec product quality monitors are broadcast round-the-clock to control system and maintenance personnel. Data is analyzed to determine the optimum times for maintaining and calibrating the instruments that provide Sinopec’s production KPIs.
ASM leverages statistical analysis based on the ASTM 3764 industry standard. This identifies recurrent deviations of measured values from a normal distribution, monitoring and validating analyzer operations in real time. ASM is based on a Simatic platform including S7 universal controller and the WinCC SCADA system monitor. More from www.oilit.com/links/1111_63.
