3 ENERGY BALANCES ON REACTIVE PROCESSES * ENERGY BALANCES ON REACTIVE PROCESSES * Generally it is the same as the procedures used in solving the energy balances for the non-reactive system: - FLOWCHART! - MATERIAL BALANCES TO DETERMINE STREAM COMPONENTS - REFERENCE STATES - INLET-OUTLET ENTHALPY TABLE - CALCULATE H - SOLVE THE ENERGY BALANCES BY INCORPORATING THE HEAT OF REACTION INTO THE EQUATION

4 ENERGY BALANCE EQUATION Generally, the energy balance equation for any process unit is given as: Input + Generation - Output - Consumption = Accumulation Enters through system boundaries Produced within system only for reactive system (+) or (-) Leaves through system boundaries Consumed within system only for reactive system Buildup within system only for transient operation
