Minimize Material Imbalance and improve Data Quality with Software-Based Reconciliation and Measurement Audits

Achieve significant improvement in Material Imbalances thorough the use of high edge technology for Data Reconciliation and Measurement Audits. How to keep imbalances at their minimum? Join our technology experts as they present:

1. The use of Sigmafine on-line data reconciliation software for calculating a correction for each measurement point to close the material balance.
2. Comparison of the calculated correction with a defined permissible limit to identify and continuously monitor the poorly performing measurement points.
3. Measurement audits to assure quality of the acquired measurement data and identify errors and significant sources of uncertainty.
4. Data reconciliation to identify the root causes of observed imbalances, monitor the measurement system performance, and schedule maintenance of measurement instruments.
5. An insight into how an Export Terminal imbalance investigation was conducted and solved using measurement audit:

   • Problem: High material imbalance was observed at propane and butane storage, and export facilities
   • Solution: Measurement audit revealed that the imbalance was due to inaccurate Meter Factors being accepted following uncontrolled proving activities, and poor performance of the existing rundown meters. Application of Sigmafine data reconciliation software detects the poor performing measurement points.
   • Results: It was recommended to replace the flow meters and passing valves. 32 meters of different sizes were replaced by Micro Motion Elite series, and imbalance was improved by 4 %.
