Homework 1: Material \& Energy Balances 1 Example: Suppose 200mol/s of liquid methanol and 30% excess oxygen are fed to a reactor at 25C, a 50% fractional conversion of methanol is obtained, and the products are brought back down to 25C. You wish to calculate Q(kJ/s). 2CH3OH(I)+O2(g)2CH2O(v)+2H2O(I)Hro=326kkJ 2- Ethyl alcohol is produced by fermenting maltose (a sugar) in a continuous fermentation process. The reaction is: maltoseC12H22O11(s)+H2O(l)ethanol4C2H5OH(l)+4CO2(g) Maltose at 40C and 50% excess water at 25C are fed to the process. The maltose reacts completely. The process effluents are liquid ethanol and liquid water at 40C and carbon dioxide at 100C. The standard heat of combustion of maltose to form CO2(g) and H2O(l) is -5649.1 kJ/mol. Calculate the standard heat of the reaction, and the required net heat transfer to or from the process (kJ/100mol maltose fed), using the heat of reaction method for the energy balance
