All other costs are close to the average values found for typical chemical plants. On the basis of this information, estimate the total direct plant cost, the fixed-capital investment, and the total capital investment. Estimate by the turnover ratio method the fixed-capital investment required in 2000 for a pro- posed sulfuric acid plant (battery-limit) which has an annual capacity of 1.3 108 kg/yr of 100 percent sulfuric acid (contact-catalytic process), using the data from Table 6-11, when the selling price for the sulfuric acid is $86 per metric ton. The plant will operate 325 days/year. Repeat the calculation, using the cost capacity exponent method with data from Table 6-11 6-9 6-10 The total capital investment for a chemical plant is $1 million, and the working capital is plant can produce an average of 8000 kg of final product per day during a selling price in dollars per kilogram of product would be necessary to gve S100,000 If the plant can produce an average of 8000 kg of final product per day during 36 a turnover ratio of 1.0
