Predict Heat Exchanger Fouling

Heat exchanger fouling at polyethylene process manufacturers mean that batch cycles get longer and that results in lower plant yield. Heat exchangers foul over time with usage and process engineers do U coefficient monitoring calculations intermittently in Excel.

Solution

Perform U coefficient calculations weekly and run a predictive model to determine when the heat exchanger performance will be below the required process requirements. Recommendations with business rules close the loop on maintenance actions.

Benefits

More than 9 months notification before a failure event. Eliminate unplanned maintenance on heat exchangers.
