Coil or Jacket Plus External Heat Exchange

Internal Coil or Jacket Plus External Heat Exchange. 11-19... 

Interna] Coil or Jacket Plus External Heat Exchanger This case can be most simply handled by treating it as two separate problems. M is divided into two separate masses Mi and (M — Mi), and the appropriate equations given earlier are apphed to each part of the system. Time 0, of course, must be the same for both parts. 

The first step is to calculate limits for the reaction volume. One CSTR will give the maximum volume and a plug-flow reactor will give the minimum volume. The total reaction voliune for multiple CSTRs will lie somewhere between these two limits. After calculating the reaction volume, calculate the required heat transfer and the heat-transfer area. Then, either select a jacket, a coil, jacket plus a coil, or an external heat exchanger.
