A new process to produce adipic acid from cyclohexene has been developed. The fixed capital investment of the process that utilizes 800 ktons/year cyclohexene was estimated to be 150 million in 2015. The process yield is 40%. A larger plant which produces 750 ktons/year of 1181 Question 3 adipic acid is to be built in 2021. The scaling factor for this process has been found to be 0.65. 3.1. Since a cost index for 2021 is not available, determine the average annual escalation for the period that the cost indices are available. (4) 3.2. Estimate the cost of the 750 kton/year adipic acid plant in 2021. A contingency of 15% should be included. 3.3. Estimate the cost of the 750 kton/year adipic acid process given that the process consists of 6 functional units. (4) 3.4. Determine the selling price of adipic acid (in 2021) that will give a turnover ratio of 2.6.
