 Exchanger Design: Dynamic Retrofit Test™


Dynamic Retrofit Test™

Hexxcell Dynamic Retrofit Test™ is a predictive approach to test performance of a proposed retrofit design in Hexxcell Studio™ using historical plant data and assess how the exchanger would have performed if in operation over a given period.


It allows identifying benefits in furnace savings as a result of reduced fouling in the retrofitted exchanger taking into account complex network interactions.​

Key Benefits

  1. Quantitative assessment of benefits and drawbacks of re-design:

    • Performance

    • Fouling rates

    • Network interaction

    • Pressure drop

  2. Estimated savings in terms of:

    • Heat duty at the heat exchanger

    • CIT

    • Heat duty at the furnace

  3. Estimation of economic trade-offs and ROI of various retrofit/mitigation options
