Course Objectives

The course aims to prepare the students to derive and solve mass and energy balances on various chemical process systems.

Upon completion of this course, a student should be able to:

1. Formulate mass and energy balances for nonreactive and reactive processes.

2. Use tables and charts to obtain physical property data needed to solve problems on material and energy balances.

3. Perform material and energy balance calculations for the processes involving solvent/solute systems for which enthalpy-concentration charts are available.

4. Solve engineering problems in a professional manner.

Course Description

Principles of energy conservation, enthalpy, standard reaction heat, fuels and combustion processes. Unsteady state mass and energy balances. Application of mass and energy balances to industry.

Course Outcomes

a. An ability to apply knowledge of mathematics, science and engineering.

c. An ability to design a system, component or process to meet desired needs.

e. An ability to identify, formulate, and solve engineering problems.

k. An ability to use the techniques, skills, and modern engineering tools necessary for chemical engineering practice.

i. Recognition of the need for, and an ability to engage in life-long learning.

f. An understanding of professional and ethical responsibility.
