Tank Flow Examples

1 CONFLOl, CONFLO 2 and CONFLO 3 -Continuous Flow Tank 

Liquid flows from an upstream source, at pressure Pi, via a fixed position valve into the tank, at pressure P2. The liquid in the tank discharges via a second fixed position valve to a downstream pressure P3. The tank can be open to atmosphere or closed off to the atmosphere and can work either under isothermal or adiabatic temperature conditions. The detailed derivation of this problem is discussed both by Franks (1972) and Ramirez (1976, 1989). Data values in the problem are similar to those of Ramirez, who also presented simulation studies. 

5 Simulation Tools and Examples of Chemical Engineering Processes 

The flow through each fixed-position valve is given by 

Both the upstream pressure P, and final downstream pressure P3 are fixed, together with the atmospheric pressure Pq.

In this chapter the simulation examples are described. As seen from the Table of Contents, the examples are organised according to twelve application areas Batch Reactors, Continuous Tank Reactors, Tubular Reactors, Semi-Continuous Reactors, Mixing Models, Tank Flow Examples, Process Control, Mass Transfer Processes, Distillation Processes, Heat Transfer, and Dynamic Numerical Examples. There are aspects of some examples which relate them to more than one application area, which is usually apparent from the titles of the examples. Within each section, the examples are listed in order of their degree of difficulty.
