Using the problem definition given in Figure 5.3, calculate n-C4 flow rate in the distillate product, if the debutanizer column has 18 (actual) plates.
The concentration of i- C5 should be <1 mole% of total C4’s and lighter compounds in the distillate product.
Column efficiency =75%, Reflux correction factor =1.5
Mean tower conditions: 210°F and 110 psig
Select appropriate light and heavy keys, and use the K values for the corresponding key compounds using the chart given in Figure 5.4 at the mean tower conditions.
Once you have calculated your answer, post it in the Exercises Dropbox inside the Lesson 5 folder in Canvas.
If possible, submit a Microsoft Word, or Excel document, showing all the steps in your calculations, indicate the K values you read from the nomograms, and assumptions, if any. You may submit scanned images or clear handwritten pages as a pdf that is less than 2 MB in size.
