Textbook: Felder, R. M., Rousseau, R. W. and Bullard, L.G., Elementary Principles
of Chemical 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 Prerequisites: Chem 126 (or Chem 122)
Co-requisites: 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.

Policy on Academic Integrity:
Members of the NJIT community are expected to be honest and forthright in
their academic endeavors as stated in the academic integrity code,
Course Requirements and Grading Policy:
Students are expected to attend class and should sign the yellow attendance sheet at every class.
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. (Do not put homework assignments in my mailbox). Late homework assignments will have half of the points deducted for that assignment. (A homework assignment is late if it is handed in after the instructor begins covering the homework assignments in class.) 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.
