Course Description

This course provides a detailed and in-depth analysis to the principles of chemical kinetics, and reactor analysis and design. The topics in chemical kinetics include: rate constants, reaction order, rate equations for elementary and complex reactions, kinetic data analysis, and product distribution. In reactor analysis and design, discussion is focused on ideal reactor systems and arrangements, including batch reactors, plug flow reactors, continuous stirred tank reactors, and recycle reactors. The last part of the course considers homogeneous and heterogeneous catalytic reactions. The design component consists of how to make an appropriate choice of reactor type and operating conditions to optimize a desired product; sizing such reactors and determining conversion levels under various conditions of temperature and pressure; determination of reaction kinetics from experimental data.

PREREQUISITES:  CHEE 210, (CHEE 222 or MINE 201), or permission of the department.

Objectives and Outcomes

The objective of this course is to develop general methodologies for analysis and design of a variety of systems (chemical, biochemical/biological, polymer, electrochemical) for which engineering of reactions is needed. In the first part of the course, basic concepts of chemical kinetics and chemical reactor design as related to simple reaction systems will be introduced. Topics covered will include the general mole balance, reactor types, conversion and reactor sizing, rate laws and stoichiometry and isothermal reactor design. In the second part of the course, we will build upon the concepts developed in the first half of the course to describe real systems that deal with complex reactions and non-ideal reactors. Topics to be covered will include non-isothermal reaction design (energy balances), multiple reactions and reaction pathways, non-ideal reactors/residence time distribution (time permitting), and heterogeneous reactions (time permitting).

Specific course learning outcomes include:

CLO DESCRIPTION INDICATORS
CLO1 Calculate operating parameters (size, flowrates, conversion, etc.) for isothermal and non-isothermal operation of ideal well-mixed batch and continuous reactors, and for ideal plug-flow reactors. KB Proc (c)
CLO2 Formulate a set of consistent material and energy balance equations to describe operation of batch, semi-continuous and continuous reactor systems with single or multiple reactions, operating with and without heat exchange. KB Proc (a)
CLO3 Develop stoichiometric tables and formulate an overall rate expression from a series of elementary mechanistic steps, taking into account the dependence of temperature, pressure and concentration, as well as the requirement of thermodynamic consistency for reversible equations. KB Proc (b)
CLO4 Choose an appropriate reactor type and operating conditions to achieve a desired output such as reactant conversion, selectivity and yield. KB Proc (c)
DE (c)

This course assesses the following attributes at the 3rd year level:

Knowledge base (KB):  Proc (a) Formulates and solves steady-state and dynamic mass and energy balances for a chemical process. Proc (b) Analyzes kinetic mechanisms, identifies rate limiting steps and develops expressions to describe reaction rates for non-catalytic, catalytic, or electrochemical processes. Proc (c) Applies engineering principles to do engineering calculations and size various unit operations, including pumps, heat exchangers, separation processes, and reactors.

Design (DE): (c) Design a product, process or system to resolve a problem, that meets specified needs (with appropriate attention to health, safety, environmental, economic, regulatory, cultural, societal and stakeholder needs), and subject to appropriate iterations.

Relevance to the Program

This 3rd year course is the main course covering the engineering science of chemical kinetics, reactor analysis, as well as reactor design. The engineering science and reactor design skills taught in this course are considered essential for any practicing Chemical Engineer. The knowledge acquired in this course is required in CHEE 323 “Industrial Catalysis” and CHEE 470 “Design of Manufacturing Processes”. The course assumes knowledge of 2nd year thermodynamics, as well as knowledge of material covered in CHEE 222, process dynamics and numerical methods.
