Issues regarding the calculation of the height of a packed tower
Thread Content
I’ve been preparing for the registration exam recently. While reviewing the material, I noticed that when dealing with calculations related to the height of fill towers, my results were always higher than the standard answers. What’s going on? I’m using the review guide for the Basic Examination (Part 2) for the Registration Examination for Chemical Engineers, published by Tianjin University; it’s questions 90 and 91 on page 265.
Is the poster a graduate of East China University of Science and Technology? The equations for gas-liquid equilibrium in the textbooks from Tianjin University are different from those at East China University of Science and Technology.
No, I used the formulas from the Tianjin University textbooks to do the calculations!
H=Nog*Hog; perhaps some of the experience values were entered incorrectly.
It depends on whether there are experience-based values; but even if so, the differences aren’t significant. You can find books on principles of chemical engineering; use different methods to do the calculations, and it’s sufficient to understand the principles behind them.
The theoretical plate height and the number of plates can be calculated using the tray column method, and the column height can then be determined ultimately based on the plate efficiency
