This document provides an overview of the Chemical Process Principles I course, including the course outline, recommended textbooks, distribution of grades, learning practices, and objectives. The course covers units, dimensions and conversions, gas laws, stoichiometry, material and energy balances. It aims to introduce calculation techniques in chemical engineering and teach students how to formulate and solve material and energy balances through practice. The major topics will include background information, material balances, behavior of gases/liquids/solids, and energy balances.

7. Good Learning Practices
(Learn How to Learn)
 People learn by practicing and reflecting
 Not by watching and listening
“You learn by doing”
 Learning involves more than memorizing
 Recording, copying, and outlining notes
will be of little help.
Practice will help you to apply your
knowledge.

8. Suggestions to Enhance your
Learning
 assimilate, and practice your skills in solving
pertinent problems.
 Exchange ideas.
 Learn Everyday
 Seek answers to unanswer questions
 Employ active reading

9. What Do Chemical Engineers
Do?
 Intriguing, challenging, and flexible profession.
 Work in wide variety of industries
 focus on design, operation, control,
troubleshooting, research, management, and
even political(environment and economics
concerns)

16. Objectives
This subject is not an introduction to chemical
engineering as profession. We will focus instead
on five general objectives
1. To introduce you to the principle and calculation
techniques used in chemical engineering.
2. To acquaint you with what material and energy
balances are, and how to formulate and solve
them.
3. To assist you in learning efficient and consistent
methods of problems solving so that you can
effectively solve problems you will encounter
after leaving institute.

17. 4. To offer practice in defining problems,
collecting data, analyzing the data and
breaking it down into basic patterns, and
selecting pertinent information for application.
5. To review certain principles of applied
chemistry.

18. The major portion of the subject comprises of
four parts.
Part 1. Background information
Part 2. Material Balances
Part 3. Behavior of gases, liquids and solids
Part 4. Energy Balances
 Part 1 and 3 will be covered in CPP-I and remaining will
be in CPP-II.

19. Part 1. Background information
1. Dimensions, Units, and their Conversion
2. Moles, Density, and Concentration
3. Choosing a Basis
4. Temperature
5. Pressure

20. The Need for Review
1. From experience we have found it necessary
to restate these familiar basic concepts in
some what more precise and clearer fashion.
2. You will need practice to develop your ability
to analyze and work engineering problems.

21. The bridge to success

22. You should already be familiar
a. Mole and mole fraction
b. Density and specific gravity
c. Measurement of concentration
d. Temperature
e. Pressure
A firm grasp of this information(Part 1) will help
guarantee “plug and play” acquisition of the
information in remaining parts.

23. You will find that adding new ideas and
techniques will be as easy as copying and
paste images in a computer.
Consider the story on next slide;

24. One night a group of nomads were preparing to
retire for the evening when suddenly they were
surrounded by a great light. They Knew they
were in the presence of celestial being. With
great anticipation, they awaited a heavenly
message of great importance that they knew
must be especially for them.
Finally, the voice spoke.
“ Gather as many pebbles as you can. Put them
in your saddle bags. Travel a day’s journey and
tomorrow night will find you glad and it will find
you sad.”

25. After the light departed, the nomads shared their
disappointment and anger with each other. They
had expected he revelation of a great universal
truth that would enable them to create wealth,
health, and purpose for the world. But instead
they were given a menial task that made no sense
to them at all. However, the memory of the
brilliance of their visitor caused each one to pick
up a few pebbles and deposit them in their saddle
bags while voicing their displeasure.

26. They traveled a day’s journey and that night
while making camp, they reached into their
saddle bags and discovered every pebble they
had gathered had become; a diamonds. They
were sad they had not gathered more pebbles.

27. DIMENSIONS,
UNITS, AND
THEIR
CONVERSION

28. UNITS AND DIMENSION
 Engineers and scientists have to be able to
communicate not only with words but also by
carefully defined numerical descriptions.
 Columbus proposal rejected by the Portugal
King John, because Portuguese experts
believed that the distance to Indies was
10,000(U.S) miles four times Columbus
estimated 2,500 (U.S) miles.
 Read the news report that appeared in the
Wall Steet Journal. June 6, 2001, on page A22

29. SEOUL, South Korea--- A mix up in the cockpit
over whether altitude guidance was measured
in feet or meters led to the crash of a Korean
Air Lines McDonnell Douglas MD-11 freighter
soon after takeoff in Shanghai in April 1999,
investigator said.
The crash killed all three crew members. Five
people on the ground were killed and 40 more
were injured when the plane went down in light
rain onto a construction site near Shangai’s
Hongqiao Airport.

30. According to summary of the crash report
released by South Korea authorities, a Chinese
air-traffic controller directed the pilots to an
altitude of 1,500meters(4,950feet).The plane
was climbing rapidly to that level when the
copilot told the pilot he thought the instructed
height was 1,500feet, equivalent to 455
,meters. The international aviation industry
commonly measures altitude in feet, and the
confusion led the pilot to conclude the jet was
almost 1,000 meters too high, so he quickly
moved the controls to lower the plane. As the
plane descended, the pilot realized the error
but couldn't correct the mistake in time.

31. South Korea Minister of Construction and
Transportation said Korean air Lines would
lose the right to serve the Seoul-Shangai cargo
route for at least two years because of error by
the pilots. Korean air Lines said it would appeal
the decision………………………..

32. Reality Check...
Are units really
important?
Is checking your
work and your
team’s work
really important?
