WebIt was found that the pressure drop increased with boil-up rates as predicted whereas the column efficiency and number of theoretical plates did not show the expected trend. The column efficiency was expected to increase as the input power increases. However, the column efficiency decreased from 29% to 24% as the input power increase from 0 to ... WebThe boilup ratio is the fractional amount of liquid that is boiled back into the column to the amount of liquid leaving. Step 3. Choose Actual Reflux Ratio: As the reflux ratio increases, the number of trays and thus the capital cost of the column decreases.
