Energy balance and components

Unfortunately, when one first starts the calculation with the initial guesses for all tenperatures, vapor, and liquid flow rates, the energy balance, component mass balance, and equilibrium functions will not equal zero. The Newtonian method is used to develop new values for the variables to calculate enthalpies and K values. To use the Newtonian method, Naphtali and Sandholm developed derivatives for the changes in all variables. Note that the energy balance (and component mass balances and equilibrium relationships) on plate j depend only on the variables on plates j-1, j and j+1. For the energy balance (EB) function on... 

For this example the procedures for the hybrid model design and the sub-model design, as described above, are followed. As a consequence of the requirements, for the hybrid model, all known balances involved are incorporated density balance, energy balance and component balances for monomer, hydrogen, non-activated catalyst, and activated catalyst. The volume of the reactor is constant. The reaction rates for the chain propagation, chain termination, catalyst activation and catalyst deactivation, determine the shifts between the component balances. For these rates, fuzzy relationships are birilt.
