• RR-6 The Second Law Efficiency of Process Heat Exchangers

    April 12, 2024
    An efficiency is defined for process heat exchangers using the second law of thermodynamics. This parameter accounts for the unavoidable sources of irreversibility in a real heat exchanger—e.g., heat transfer over a finite temperature difference and flow friction. Its definition is based on the destruction of flow availability, which is a function of the...

  • Insights From the Second Law

    January 08, 2024
    In the December issue of Hydrocarbon Engineering, Thomas G. Lestina and Kevin J. Farrell examine how using a second-law approach can help to improve the efficiency and environmental impact of process heat exchangers. If you're having difficulty viewing the article above, you can visit this link instead....
