Question: ethyl alcohol is produced by fermenting maltose a sugar in...

Question details

Ethyl alcohol is produced by fermenting maltose (a sugar) in a continuous fermentation process. The reaction is: C12H22011()+ H20) 4C2H;OH(l) 4CO2(9) Maltose at 40°C and 50% excess water at 25°C are fed to the process. The maltose reacts completely. The process effluents are liquid ethanol and liquid water at 40°C and carbon dioxide at 100°C. The standard heat of combustion of maltose to form CO2(g)and H2O() is-5649.1 kJ/mol Calculate the standard heat of the reaction, and the required net heat transfer to or from the process using the heat of reaction method for the energy balance Thermodynamic data: Heat capacity from maltose cp 0.4882 kJ(molC) assumed to be constant between 25 and 50 oC Liquid species heat capacity Cp A BT + CTDT3 [J/(kmol K] Ahco2 (100 °C) 2926.8 J/mol [JImol] CO H2O () C2H,OH() 234950 1.0264x 10. 1.3963 x102 -3.0341 x 102 2.0386 x 103 -393500 285800 2.7637 x 105 2.0901 x 10-3 8.1250 x 100 1.4116 x 102
