The following is a simplified schematic of a corn ethanol process:

Milled Corn + Water --> Jet Cooking --> Fermentation --> Distillation and Dehydration --> 100% Ethanol

a. Calculate the theoretical yield of ethanol per kg of milled corn. (10 pts)

b. If the feed is slurry that contains 30 wt % milled corn, what is the highest ethanol concentration (wt. %) you would expect to see after fermentation? (10 pts)

The composition of corn is: starch - 62%, protein - 8%, water- 13%, fiber- 8%, fat - 7%, ash - 2%

A liquid mixture containing ethanol (55.0wt%) and the balance water enters a separation process unit at a rate of 90.5 kg/s. A technician draws samples of the two product streams leaving the separator and analyzes them with a gas chromatograph, obtaining values of 86.2wt% ethanol (product stream 1) and 10.9% ethanol (product stream 2). The technician then reads a manometer attached to an orifice meter mounted in the pipe carrying product stream 1, converts the reading to a volumetric flow...

Ethanol (CH3CH2OH) can be produced from sugars and starches in crops such as corn or sugarcane. Ethanol is used as a gasoline additive and when completely burned, it combines with oxygen to form CO2 and H2O. Write the balanced equation for the complete combustion reaction and calculate the net energy change per mole of ethanol. Bond Energy C – H → 416 kJ/mol O – H → 467 kJ/mol C – C → 356 kJ/mol C – O → 336...
