Cellulose is to be burned in a waste-toenergy facility. The chemical equation for cellulose is C6H10O5. The atomic weights of C, H, and O are 12, 1, and 16, respectively.
a. Calculate the stoichiometric oxygen necessary for the combustion of cellulose.
b. Calculate stoichiometric air.
Pervaporation is used to produce nearly pure ethanol from a feed with 90 percent ethanol and 10 percent water. The feed enters at 80°C, and the design calls for reheating the liquid after the temperature has dropped to 70°C.
