The Total Capital Investment for the project is 101 M$. The Net Present Value of the project at an interest rate of 0.1 and an EpB price of 1.5 $/kg is 90 M$. The Pay Out Time is just below 5 years and the Internal Rate of Return is 0.24.
The cost driver for the production of EpB is the purchase of the reactant butadiene. The uncertainty of the NPV is mainly caused by the uncertainty of the price of the product EpB. At an interest rate of 0.1 the NPV of the project becomes zero at an EpB price of 1.1 $/kg. The project is very profitable and the sensitivity analysis shows that the feasibility of the project is assured.
