The calculation should cover overall mass and energy balance (mass flow rates, enthalpies, and temperatures) of all streams. Hand calculations must be used in details. For mass and energy balance around the reactors, use the extent of reaction and the heat of formation methods ONLY.

Requirements:

1- Mass & Energy balance for all streams (conditions of all streams should be stated)

2- Heat of formation method is the only accepted method to calculate the enthalpies for the reactors

3- Extent of reaction method is the only accepted method to calculate mass and energy balance for the reactors

4- all assumptions and equaltions must be stated

The problem statement and the PFD is attached. Material and energy balance must be calculated based on the attached Process Flow Diagram.
