To provide students with the skills necessary to understand
the complexities of industrial chemical reactors and the
reactions carried out in them. The analysis and design of
reactors will also be studied, as well as the fundamentals of
reacting systems.
Content
Review of basic chemistry necessary to study reactors
Stoichiometry, order of reaction, thermodynamic
considerations, especially effect of temperature on heats
of reaction and heat capacity data, van't Hoff equation,
Chemical Kinetics and the effect of temperature on rate
of reaction, Definition of reaction rate, other variables
affecting reaction rate, kinetics of homogeneous
reactions.
Interpretation of batch reactor design
Constant volume batch reactor and analysis of data,
Variable volume batch reactor and analysis of data.
Types of ideal reactors
Definition of ideal reactors, continuous stirred tank
reactors, plug flow reactors, mixed flow reactors,
reactors in series and parallel
Design for single reactions
Size comparisons of single reactors, CSTR versus PFR
for first and second order reactions.
Tem~erature and Pressure effects
Heats of reactions and equilibrium constants - the effect
of temperature and pressure, general design procedure,
optimum temperature progression, heat effects, adiabatic
operation, non adiabatic operation.
Non ideal flow in reactors
residence time distribution in reactors, age distribution
curves, use of tracer information, diagnostics for poorly
rn
performing equipment,

To apply scientific and economic principles in selecting and
specifying major equipment required to carry out particular
processes: heat and mass transfer equipment, equipment for
storage and transport of fluids. Apart from the physical and
chemical principles of the processes, other factors are also
