This report presents a cost analysis of n-Butanol production from propylene and syngas. The process examined is similar to the LP OXO technology jointly licensed by JM Davy and Dow, employing Selector 30 catalyst. In this process, the production ratio of n- to iso-butyraldehyde in the oxo reaction is about 30. The isobutyraldehyde is separated as a by-product and the n-butyraldehyde is hydrogenated to form n-Butanol as the final product. This report examines one-time costs associated with the construction of a United States-based plant and the continuing costs associated with the daily operation of such a plant. More specifically, it discusses: * Capital Investment, broken down by: - Total fixed capital required, divided in production unit (ISBL); infrastructure (OSBL) and contingency - Alternative perspective on the total fixed capital, divided in direct costs, indirect costs and contingency - Working capital and costs incurred during industrial plant commissioning and start-up * Production cost, broken down by: - Manufacturing variable costs (raw materials, utilities) - Manufacturing fixed costs (maintenance costs, operating charges, plant overhead, local taxes and insurance) - Depreciation and corporate overhead costs * Raw materials consumption, products generation and labor requirements * Process block flow diagram and description of industrial site installations (production unit and infrastructure) Keywords: Oxo Alcohol, Butyl Alcohol, n-Butanol, Johnson Matthey, Dow, LP Oxo, SELECTOR
