ChE221: Material and Energy Balances

Prof. Davis

Course Syllabus

Course Description:

Introduction to the principles and techniques used in chemical engineering. Basic concepts of mathematics, physics, and chemistry are applied to solving problems involving stoichiometry, analysis of chemical process systems, and material and energy conservation equations. Also includes methods for estimation of thermodynamic and chemical properties of real fluids for engineering calculations, basic chemical equilibrium, and unsteady-state balances.

Course Objectives:

The primary goal of this course is to prepare you to solve chemical engineering problems you will encounter in the ChE program.
By the end of this course, you should be able to:

• Demonstrate professional behavior including behaving in the classroom, being punctual, and completing problems in an organized and timely manner
• Define and properly use “chemical engineering vocabulary” words
• Write and solve material and energy balance equations for single-units, multi-unit processes, processes with recycle and bypass, and reactive processes
• Solve material balance problems for processes which contain multiphase equilibria
• Convert quantities from one set of units to another quickly and accurately
• Define, calculate, and estimate properties of process materials including fluid density, flow rate, chemical composition variables (mass and mole fractions, concentrations), fluid pressure, and temperature
• Draw and label process flowcharts from verbal process descriptions
• Carry out degree-of-freedom analyses
• Perform vapor-liquid equilibrium calculations for systems containing condensable components and for ideal multi-component solutions
• Calculate the change in enthalpy for process fluids undergoing specified changes in temperature, pressure, phase, and chemical composition
• Solve combined mass and energy balance problems for processes involving external heat and work in open and closed non-reacting steady-state and transient systems.
• Incorporate the results of these calculations into process material and energy calculations
• Use spreadsheets (EXCEL) to solve material and energy balance problems
• Evaluate potential safety hazards in chemical processes
