Consultation on TEA results #98

Closed zasddsgg closed 4 months ago

zasddsgg commented 4 months ago

Hello, could I consult you how to see the formula for each value in the Itemized costs and Cash flow worksheets in the excel file obtained from code sys.save_report, since only the final value is in the result, which is not conducive to checking and verifying the result. Thanks for your help. Wish you a good day.

@zasddsgg, for CellulosicTEA we follow the exact same cash flow analysis procedure used by Humbird's 2011 NREL report. You can find all the formulas there (or look at the TEA code). For itemized cost of each unit operation, you can check the code for each unit operation, the references in the documentation, or look at the supplementary information to some of our publications. For the most part, they come from Warren Seider's Product and process design principles. This book also contains a great chapter on cashflow analysis that we follow in detail, this could be a great reference for you to read to understand details in the TEA procedure.

Thanks,
