TUBEMIX - Non-Ideal Tube-Tank Mixing Model

2 TUBEMIX - Non-Ideal Tube-Tank Mixing Model 

Non-ideal mixing conditions in a reactor can often be modelled by combinations of tanks and tubes. Here, three, stirred tanks are used to simulate the tubular, by-passing condition. 

The model involves mass balances according to the scheme of Fig. 5.114. For the tubular by-pass the balances, for reactant A, have the form 

Tank reactor, with a bypass and a dead-zone. The bypass Is modelled by a series of tanks. The reaction is nth-order.

For the tubular bypass flow representation, the balances for reactant A have the form 

The final outlet concentration is given by the balance at the mixing point
