Welcome to this website devoted to chemical engineering calculations

This website provides several spreadsheets for Chemical Engineering applications developed using Excel and VBA programming. They demonstrate mehodology for Chemical Engineering, advanced use of spreadsheets, and numerical methods. Hopefully you will find these calculations to be both instructional and useful. The spreadsheets are available free for download and any none commercial use, but I retain the rights for future publication or software development. I hope you enjoy visiting the website. - Jeff Munic, P.E.

Instructions for Spreadsheets:  The spreadsheets are prepared in Excel 2003 and they should be compatible with that version and later versions. Simply double click on the file and save the file to your computer. To use the Macros in the spreadsheets, set your macro security to medium using Tools|Macros|Security in Excel.  A high security setting may also work because the spreadsheets are digitally signed. Assuming that you view this as a trusted source, enable the macros if Excel prompts you to do so.  If you need to view the macros in Excel, go to Tools | Macros | Macros...|  and click on the macro name that you want to look at.  The code should be relatively understandable to those familiar with programming languages such as C, Fortran or Basic.

 Disclaimer:  These programs are for educational use and feasiblity level estimates and not for detailed design.  They have currently not been peer reviewed although I plan to have them reviewed by others and/or compared to results from commercially-available programs.  The computer code does not have the same level of user error checking or software quality control as commercial code should have.  The chemical engineering shortcut methods have limitation inherent in the method that the user needs to be familar with.  The sources for input data are from reliable publications and are referenced, but I am making no claim as to the accuracy of published laboratory research performed by others.  ChemEcalcs has no association with the consulting firm, chemecalc, in Queensland Australia .
