CBE20255 Introduction to Chemical Engineering Analysis demonstrates the use of mass and energy balances for the analysis of chemical processes and products. The notebooks in the repository show how to prepare and analyze conceptual flowsheets for chemical processes, perform generation-consumption analysis, and perform basic engineering calculations for stoichiometry, reactor performance, separations, and energy analysis.
The notebooks demonstrate these basic chemical engineering calculations using Python. The notebooks can be open directly in Google Colaboratory where they can be run, edited, shared, and saved to your Google Drive. Alternatively, the notebooks can be downloaded and executed on your computer. These notebooks were developed and tested using the Anaconda distribution.

Note on the use of Python. The Python used in these notebooks is deliberately limited to a core set of language
features. These notebooks use scalar variables and lists of scalar variables to represent data. Also used are
arithmetic, math, print, and plotting functions from the matplotlib.pyplot library. Functions created with def
and lambda are used when root-finding calculations are required. List comprehesions are used on occasion when the
result is more readable code. The Sympy library for symbolic math is used extensively for writing mass balances. Other
libraries included numpy, math, and the root-finding functions from scipy.optimize. Notebooks with more advanced
use of Python, such as dictionaries, are marked with an asterisk.
