Textbook: Felder, R. M., Rousseau, R. W. and Bullard, L.G., Elementary Principles

ofChemical Processes, Fourth Edition, John Wiley & Sons, Inc., 2016.

Course Description and Objectives: Analysis of chemical processes is introduced,

emphasizing steady and unsteady state mass and species balances. This course uses

primarily chemistry and algebra to determine, for a wide variety of processes and

applications, the flow and concentrations of different chemical species.

Course Prerequesites: Chem 126 (or Chem 122)

Corequisites: Math 112 and CS 101

CHE210W – Workshop

Attendance for the CHE210W workshop which is run in conjunction with CHE210 lecture

Courseis mandatory. At the end of the semester, a Grade of Satisfactory (S) or Unsatisfactory

(US) willbe given as your workshop grade depending upon your performance in the workshop.

You must receive a Satisfactory (S) grade in the workshop to pass the CHE210 course.

Course Requirements and Grading Policy:

Homework Assignments: A homework assignment will be given at the end of most classes. Homework assignments are due at the beginning of the next class and should be placed on my desk, before homework problems are covered when the class starts. Late homework assignments will have half of the points deducted for that assignment. Late homework assignments will not be accepted after the last day of class. (Homework assignment grades will comprise 5% of the final grade).

ChE 210 Course Objectives

MATERIAL BALANCES. To do well in this course, you should be able to:

 Carry out conversion between the different systems of units

 Explain/Apply dimensional homogeneity

 Represent quantitative data using significant figures, scientific notation or to a given precision

 List and define all the process variables discussed in chapter three of your text

 Calculate mass and volumetric flow rates, chemical compositions, convert between mass and molar composition and convert between mass and molar concentrations

 Calculate pressures associated with a BOURDON gauge a MANOMETER and distinguish between the different types of manometers.

 Explain the different chemical process types.

 Identify a process mode and reduce the general balance equation to describe that process.

Draw and label single and multiple-unit flowcharts.

Solve for unknown quantities in single and multiple-unit processes.

Solve for unknown quantities in a recycle or bypass stream of a given process.

 Interpret fractional conversion, limiting and excess reactants, extent of reaction, Yield, Selectivity, overall conversion, single-pass conversion, theoretical and excess air.

 Conduct material balances on given processes involving some of the above concepts.

 Calculate unknown quantities in a single or multiple-unit reacting system using either atomic balance or extent of reaction approach.

 Determine which of the two approaches (extent of reaction or atomic balance) is more appropriate for a given problem.

 Estimate the density of a liquid mixture.

 Convert to and from standard conditions (STP).

 Calculate pure component volume and pressure in an ideal gas mixture.

 Estimate real gas compressibility factor for both pure component and mixtures.

 Decide when to use compressibility or ideal gas relation in solving a material balance (see homework problems).

 Calculate real gas volume using compressibility factor equation of state.

 Solve material balance problems involving the use of real or ideal gases (see homework problems for examples)

 Estimate vapor pressures using an empirical equation and a theoretically derived equation.

 Explain relative humidity, bubble point, dew point, Raoult’s and Henry’s laws and what a distribution coefficient is.
