Saudi Aramco Total Refining and Petrochemical Co. (SATORP) has been using BELSIM’s ValiProduction solution for the daily mass balance of the refinery since 2013, with a stable application that offers desired results. This solution offers us multiple advantages :

• Daily reconciled mass balance, product wise as well as unit wise, reaching 100 % product balance without any gross error.
• Refinery official month end data to be used in SAP®, as well as GRM calculation.
• User friendly application reports, such as production account or unit yield reports, are automatically generated from the VALI reconciled results.
• Easy integration with historian system such as PI System TM, where measurements can be read, and reconciled results written back for comparison purpose.
• Alarms on degrading or under performing sensors for corrective and condition-based maintenance.
• Flexible models can adopt any changes in the refinery configuration (addition of new product code, stream or unit).

“SATORP is currently using VALI 4 and will soon upgrade the application to VALI and to take advantage of its web-based reports and more user friendly user interface“.
