Spreadsheets
Generating spreadsheets is one of my favorite hobbies which helps me record my learning and understandings in a
proper way. These spreadsheets are ranged from simple to very complicated ones, for almost all process sizing
calculations that I have seen so far. These spreadsheets enable me to perform my job easier, faster and more
effectively. I can easily check the effect of different parameters on the final results and get feeling about different
processes too.
Being dedicated to update, renew and complete my spreadsheet library, presently I have one of the most
comprehensive collections of process engineering tools. A list of spreadsheets along with their descriptions, main
inputs and outputs is available here.
The spreadsheets have been designed so that input data are entered in correct sequence from top to bottom. All
inputs and results are easily recognized by color coding (green: input, blue: text/not accessible, white: output).
Iteration and user's manipulation to obtain the desired result have been minimized by putting macros which
automatically run behind spreadsheet interface. The spreadsheets calculate the results with minimum data entry. All
curves and tables which are normally used to prepare input data or calculate final results have been entered into
spreadsheet by use of regression techniques so that there is no need to refer to any standard during calculation. You
can put those standards in the shelf!.
There are some samples made available in below section for reference. All of these spreadsheets have Chemwork
icon on top but it does not mean that they are part of Chemwork (although they can be potentially part of it in
future). This is only because most of them were developed after relaesing Chemwork V2.1.
