1. A feed of equimolar (50%) binary system mixture of (A&B components) is processed in a distillation column to achieve a mole fraction of A at the top of the column XD=0.9, while its mole fraction at the bottom product is 0.05. Component A is the more volatile component in this mixture. a. determine the number of required stages to achieve the above-mentioned purity. b. If you use tray column, how many trays are required if the tray efficiency is 85% Please use the following data to solve the problem. Please use a graph paper to draw the diagram. You may download graph paper from google if you do not have. Alpha (α) 3 Rmin 1.2 q 0.5 R=1.5*Rmin

Which among the following is FALSE for distillation equipment? a. A flash drum operates at lower pressures to vaporize the more volatile component. b. Partial condensers operate with vapor-liquid equilibrium. c. Total condensers yield reflux and distillate streams that have composition similar to the incoming saturated vapor. d. Partial reboilers yield a liquid stream that is recycled back to the distillation column.

Multi correct answers. Please select all correct answers: which of the following strategy could be used to increase the mass transfer rate inside an aerated stirred fermenter? (oxygen needs to transfer from the bubbles (gas phase) to the media which is a liquid phase (KL(Cs-C) )). Question options: Decrease bubble size Increase air flow rate Increase stirring rate Increase bubble size
