Chapter 4. Case study: Distillation
Flash distillation of binary mixture
Flash distillation consists of vaporizing a definite fraction of the liquid in such a way that the evolved
vapor is in equilibrium with the residual liquid, separating the vapor from
Chapter 8. Case study: Fiber Spinline
Introduction
Fiber spinning is a process in which an extruded liquid filament, usually a polymeric liquid, is
continuously drawn and simultaneously solidified to form a continuous fiber.
There are three fundamental pr

Thermodynamic variables
The principle of conservation of energy:
rate of change of
energy in the
control volume
=
rate at which

by heating or cooling at the boundaries of
Chapter 7. From Discrete to Continuous
Introduction
Process models are usually ODEs or PDEs. Mathematical structure is inherently continuous in the
independent variables.
Some problems are inherently discrete, either because of a spatial staging or a casc

A continuous flow stirred-tank reactor
Now, consider a tank reactor which includes a chemical reaction:
A + B+ M + N +
Control volume: by assuming that the reactor is well stirred, we can take the entire tank as the contro
Chapter 1. Introduction to Models in CBE
What is a model?
A model is a quantification of a physical process that enables prediction of process behavior.
A mathematical model of a process is a system of equations whose solution, given specified input

The mass balance for species
For homogenous medium with spatial distribution of concentration, control volume is of differential
size. The balance equation will be
