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 basic chemical engineering calculations in Python. The open in colab opens notebooks directly in Google Colaboratory where they can be run, edited, shared, and saved to your Google Drive. All you need is a browser, either Google Chrome, Mozilla Firefox, or Apple Safari. Alternatively, the render in nbviewer link allows notebooks to be downloaded and executed in a Python development distribution installed on your computer. These notebooks were developed and tested using the Anaconda distribution.

Most notebooks are 3-5 pages in length covering a single topic. Notebooks marked as examples are shorter, and present one or more problem statements with solutions.

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.
