One of the most powerful features of the Monitor™ computer program is its ability to reconcile data without significant user intervention.
Monitor™ fouling calculations use measured plant temperatures and flowrates to calculate heat exchanger fouling factors. Data Reconciliation identifies inconsistencies in the input data and produces a more consistent set of data for the fouling calculations.
Data reconciliation uses an optimization procedure to minimize errors between hot and cold side duties of exchangers by adjusting given variables. At the same time, it minimizes the difference between calculated and target exit temperatures for mixers.
Exchangers and mixers that are included in the reconciliation are called "targets". Feed flowrates and temperatures and splitter ratios are the independent "variables" that are changed to achieve the targets.
