A collection of python scripts, for doing Chemical Engineering
Currently only supports solving and drawing simple material balances. This will however likely change, as the course progresses.
Examples of a few material balances can be seen in Examples. And an example of a drawing can be seen below
Currently the top of the python file most be modified as to contain the correct values Afterwhich running the script results in a gui which helps with the calculation of destillation trays and R, given the relation between R_min and R alongside xD, zF, xB, q and an x-y diagram. When the script is done, there should now be generated two files, one for the R_min drawing and one for the tray drawing. Along side this, it prints some relevant data for calculation of R_min, in the console.
Example of a tray drawing can be seen below
- Click here to download the lastest version as a zip file
- Extract the zipfile into your chosen location
- Execute the
install_for_windows.py, which should installgraphvizalongsidepydot,sympy,tkinterandpillowif they are not installed already
- You'll figure it out! 😁
- Take a screenshot of the x-y diagram and save it in the same folder as the script.
- Modify the values at the top of the python file,
img_name,xD,zF,xB,q,R_relation. The colors and sizes of the lines can also be adjusted as you wish. - Run the script.
- Left-click on two diagonally opposing corners of the x-y diagram, a box should appear. If it aligns with the edges of the graph press enter, if not, right-click to try again.
- Click the intersection of the x-y plot and the proposed q-line, a new line should appear. If it looks as expected press enter, if not, right-click to try again.
- Click the intersection of the R_min-line and the q-line, such that the new line comes as close to the x-y plot as possible without hitting it. If it looks as expected press enter, if not, right-click to try again.
- Click the intersection of the tray-line. Repeat until xB has been passed. At that point press enter. To go back a tray, right click
