14. Python for Chemical Engineering Applications
Python used for chemical engineering tasks:
1. Process simulation: Pyomo is a Python library for modeling and
solving mathematical optimization problems. It can be used to model
and optimize chemical processes, such as distillation columns and
reactors.
2. Data analysis: Pandas is a popular Python library for data analysis.
It can be used to manipulate and analyze large sets of data, such as
process data from sensors or experiments.

15. Python for Chemical Engineering Applications
3. Visualization: Matplotlib is a Python library for creating visualizations.
It can be used to create plots and charts of process variables, such
as temperature and flow rate, to aid in understanding and analyzing
data.
4. Kinetic model: Cantera is a Python library that can be used to create
and simulate kinetic models of chemical reactions. It can be used to
model combustion reactions, atmospheric chemistry and more.
5. Equation solving: Scipy has an optimize module that can be used to
solve equations, it can be used to solve systems of non-linear
equations, which is a common task in chemical engineering.

26. High-level Language: Designed to be used and understood by humans
Low-level Language: Computer hardware can only understand a very low level
language known as machine language
Compilers: convert programs written in a high-level language into the machine
language of some computer.
Syntax: Every structure in programming language has a precise form.
Semantic: Every structure in programming language has a precise meaning

27. Using Google Colab
• Colab is an interactive editor for Python in the cloud
• To get started, open Google Colab in Chrome
• Sign in using your personal Google account
• Click ‘New Notebook’ or, if this is not an option, ‘File > New Notebook’
• Top right hand corner should look like this
• If not, click ‘connect’
27

28. Using Google Colab
• We run code in Google Colab by typing it in a code ‘cell’ and clicking the
play button
• Try the example above. We’ll explain what we wrote in one moment.
• Bonus: You can also run the contents of a cell using `ctrl+enter`

29. Printing
• Printing allows Python to talk to us. In the last example we used
printing to make Python say “Hello World”
• We can make Python say anything by writing a sentence, wrapped in
double quotes, and passing it as the input to print(…)
• The print function can also be used to perform arithmetic. Just replace
the input to of the print() with the expression you want to evaluate
• Note, in this case, we don’t need quotes. They were only to let Python
know that the input to print(…) was text
29

30. Printing
30
• You can print multiple things (which will be automatically separated by
spaces) by passing more than one input to print(…)
• We separate each input using a comma
• As we can see above, Python is happy to combine both text (using
double quotes) and arithmetic (no need for double quotes here

31. Printing Practice
31
• Print your name using the print() command
• Print your three favourite colours by passing them as three separate
inputs to print() (remember: separate each input with a comma)
• Calculate 26, multiplied by 66, add 13
• Calculate 6804 divided by 162 (hint: use / for division)
• Calculate 2 to the power of 8 (hint: use **)
• What happens if you put a mathematical expression in double quotes
when you are printing it?
• Print(“66+33”)
• Output ?
