Course Description

Introduction to the fundamentals and principles of chemical engineering, with applications to chemical and biochemical processes, via an analysis of processing units including distillation, crystallization and combustion. Specific topics include conservation equations for mass and energy, process flow diagrams, material and energy balances, chemical reaction fundamentals, and applications of the First Law of Thermodynamics.

PREREQUISITES:  APSC 131, APSC 132, APSC 172, or permission of the department

Objectives and Outcomes

The objective of this course is to develop proficiency at performing mass and energy balance calculations for single-unit and multiple-unit processes, for processes involving recycle, bypass or purge streams, and for systems involving reactions.

Specific course learning outcomes include:

  1. Draw and fully label a process flow diagram (PFD) for application of material and energy balances.
  2. Formulate and solve the material balance equations to analyze steady-state single-unit and multiple-unit processes without reaction.
  3. Formulate and solve the material balance equations to analyze steady-state processes with reaction.
  4. Formulate and solve combined steady-state material and energy balances for chemical processes.

This course develops the following attributes:

  • Knowledge base for engineering, KB-PROC (CLO 1-4):  Formulates and solves steady-state mass balances for a chemical process; formulates and solves steady-state energy balances for a chemical process; constructs process flow diagrams or P&IDs.
    • Problem analysis (CLO 2-4): Creates process for solving problem including approximations and assumptions to reach substantiated conclusions.

Relevance to the Program

This course lays the foundation for all subsequent courses dealing with chemical engineering processes and systems. It is therefore an essential prerequisite for the entire Chemical Engineering and Engineering Chemistry programs. The course assumes knowledge of first year chemistry and calculus.
