Course Description

Time–varying operation of chemical and biochemical processes is introduced. Dynamic mathematical models are formulated using material and energy balances. Effects of operational and design parameters on steady-state and dynamic operations are investigated. Numerical techniques are introduced to solve systems of algebraic and differential equations. Numerical and symbolic computation tools are used to analyze dynamic and steady-state process behaviour. (22/0/0/20/0)

Objectives and Outcomes

This course introduces basics of mathematical modeling and numerical methods for systematic analysis of transient and steady states of chemical processes.

Specific course learning outcomes include:

CLO1 Develop dynamic and steady-state models of chemical processes using mass balance, energy balance and constitutive relationships. KB-Proc(a)
CLO2 Calculate states, inputs or parameters at steady states via solving relevant algebraic equations. KB-Mathematics
CLO3 Analyze process dynamics via solving relevant ordinary differential equations. KB-Math(a)
KB Proc(a)
CLO4 Develop linearized models with deviation variables, and solve using Laplace transforms. KB-Mathematics
CLO5 Solve complex algebraic and ordinary differential equations using MATLAB built-in functions, and implement classical numerical methods on MATLAB. ET-Apply

This course assesses the following program indicators at a 2nd year level:

Knowledge base(KB)

  • KB-Mathematics Demonstrate competence in university-level mathematics
  • KB-Math(a) Selects and applies appropriate mathematical tools to solve problems that arise from modeling a real-world problem.
  • KB-Proc(a) Formulates and solves steady-state and dynamic mass and energy balances for a chemical process

Problem Analysis (PA)

  • PA-Formulate Develop appropriate frameworks for solving complex engineering problems.

Engineering Tools (ET)

  • ET-Apply Apply and manage appropriate techniques, apparatus, databases, models, tools, and/or processes to accomplish a task.

Relevance to the Program

This course builds on elementary principles of chemical engineering learned in CHEE 221.  It relies on mathematical concepts and techniques from first-year calculus and algebra.  Methods for solving differential equations learned in MTHE 225 are applied and extended.  Mathematical modeling and mathematical skills developed in CHEE 222 prepare students for CHEE 311, CHEE 315, CHEE 319 and CHEE 321.
