Select the appropriate reactor type for a given chemical conversion and
size it to meet operational goals.
-
Synthesize an appropriate multi-reactor sequence to meet operational
goals.
-
Able to identify and analyse additional problems which may be solved by
the methods of chemical reaction engineering.

mathematical models and, if necessary, choose a numerical method and/or
suitable ready-made software (for example MatLab) for solving those models on
a computer.

(Estimate the purchase and operation costs for a chemical reactor.)
-
Ability to apply knowledge of mathematics, engineering and science
-
Ability to design and conduct experiments and to analyze and interpret
data
-
Ability to design systems, components or processes to meet needs
-
Ability to use techniques, skills, and tools in engineering practice
Course Description
Course objectives:
-
Identify and determine the parameters in kinetic rate expressions for
homogeneous (and heterogeneous) reactions and for elementary and
non-elementary reactions.
-
Formulate and apply the design equations for the three ideal reactor
models (batch, CSTR, and plug flow) in the presence of both single and
multiple reactions.
-
Formulate and apply the energy balance equation to the ideal batch,
CSTR (and plug flow) reactor models, and determine required heating and
cooling loads, in the presence of both single and multiple reactions.
-
Formulate and apply the design equations and rate laws for catalytic
reactors.
