Afeed stream contains ethanol and water. the stream is fed to a distillation column. there are two products from the distillation column: an overhead product and a bottoms product. both product streams contain ethanol and water. draw and completely label (i. e., identify all variables, using total molar flow rates and mole fractions) the flowchart for this process. your chart should identify a total of 6 variables in three process streams a. b. the feed rate to the column is 480 moles/min and 40 mol% ethanol. it is desired to capture 80% of the incoming ethanol in an overhead product stream that is only 8 mol% water. determine both the molar (moles/min) and mass (kg/min) flowrates of the two product streams as well as their composition (mol%)
