The process for making cyclohexane by saturation of benzene consists of a feed-effluent heat exchanger, a saturation reactor and a product stabilizer column. Estimate the cost of a plant that produces 200,000 metric tons per year (200 kte/y) of cyclohexane using the correlation in Table 6.2 and Bridgewater’s method.
