(4d) Charlie Colwell's Achievements and Correlation

This presentation is comprised of two parts.  Part 1 will review the technical achievements of Dr. Charles Colwell as outlined below:

• Public domain papers pre-Exxon based on his PhD work at Northwestern University
• Experimental and theoretical work on mass transfer adsorption on ion exchange resins
• Public domain papers while at ExxonMobil Research and Engineering Company
• Correlations for predicting clear liquid height and froth density on sieve trays
• Estimating sieve tray efficiency in the weeping region
• His extensive work in distillation and fractionation in the upstream, downstream and chemicals sectors
  • Sieve tray mass transfer efficiency model
  • Packing mass transfer efficiency model
  • Packing capacity correlations
  • Direct contact heat transfer correlations for packings, trays and shed decks
  • Tray downcomer capacity correlations
  • Fractionator troubleshooting
  • First time applications of packings (random and structured) and high capacity tray technology
  • Computer design/rating programs for trays and packings
  • Reactive mass transfer efficiency estimation method for caustic towers

In the second part of the presentation, the Colwell correlations for predicting clear liquid height on sieve trays will be investigated further when compared against publically available experimental data.
