Topic: Production of propylene glycol from glycerol derived from palm oil.


QUESTION:
Estimate capital items, operating costs and economics of the plant. Finally, report the estimated
return.
The Detailed Factorial Method with approximately 25% accuracy must be used for detailed
economic evaluation.
Plant lifetime is fixed at 15 years.

1) Depreciation and Taxes
Calculate the depreciation using a suitable method (e.g., straight-line, declining balance) and
incorporate tax implications based on current tax laws applicable to chemical plants. 

Use following attached Process Flow Diagram as reference for this question.
