Capital project for the petrochemical process plant (downstream) is slightly different from other capital projects. It requires estimating Total Installed Cost (TIC) plus Owner cost in order to find the complete project cost. Cost estimation for petrochemical process plant is dependant upon equipment specification and definite plant facility information. In this case study, there are 2 products that will be sold in two regions. The price strategy is different so the IRR and NPV will be calculated for base case and under uncertainties and risks. Then we'll compare the IRR and NPV under different scenarios.
