Rationale for the
inclusion of course
in the program
To familiarize students with conversion of raw materials into
finished products on industrial scale using conventional and
green technology.
Semester 2nd
Credit Value (3,1)
Knowledge Area Engineering Foundation
3. 3 Objectives 1. To introduce students with the understanding of technical
and economic problems used in chemical process industries
2. To help them understanding the value of chemicals, the type
of problems met in their production, and the methods for
solving these problems in the chemical industry.
Learning Outcomes At the end of this course, students should be able to:
1. Consider the chemical processing of raw materials into useful
and profitable products.
2. Extensive use of flowcharts approach allows the students to
visualize a series of rational connected steps for a process,
greatly reducing the memorization so frequently required by
the academic chemical reaction approach.

6. Objective
The objectives may be summarized by stating that it has been the
endeavor to present the various chemical processes in a generalized form
through the correlation into flow sheets and descriptive text of the
following:
a. Unit processes: chemical change.
b. Unit operations: physical change.
c. Physical chemistry: equilibriums and reaction rates.
d. Economics: costs, statistics, and consumption.
e. Energy and power: chemical as well as electrical and mechanical.

9. Chemical Engineering
Chemical engineering is that branch of engineering concerned with the
development and application of manufacturing processes in which
chemical or certain physical changes of materials are involved. These
processes may usually be resolved into a coordinated series of unit
physical operations and unit chemical processes. The work of the chemical
engineer is concerned primarily with the design, construction, and
operation of equipment and plants in which these unit operations and
processes are applied. Chemistry, physics, and mathematics are the
underlying sciences of chemical engineering, and economics its guide in
practice.

Chemical Engineering = Unit Processes + Unit Operations
Chemical Changes Physical Changes
10. Unit Processes
The unit process is a very useful concept for technical
chemical change.
In unit process, processing of reactant in the feed takes place
i.e. reactants in feed get converted into products (by chemical
reaction)with the help of either energy supplied to the system
or generated by the system
This naturally includes the machinery needed and the
economics involved, as well as the physical and chemical
phases."

11. Unit Operations
The unit operation is a physical change connected with the
industrial handling of chemicals or allied materials; it frequently is
tied in with the unit process as when heat flows into an
endothermic chemical reaction or out of an exothermic reaction.
The unit operation may also be distinctly separated from the
chemical change as when, by "flow of fluid," a liquid is moved from
one part of an industrial establishment to another.
In unit operations the mass and concentration change takes place
(between entrance and exit points)by providing energy from an
external source and no chemical change takes place. (for example
distillation, evaporation, mixing, etc.)
