Butenes Production From Propylene Cost Analysis Butene E41a PDF Download

This report presents a cost analysis of Butenes production from ethylene using a dimerization process. The process examined is similar to CB&I Lummus Ethylene Dimerization Technology. In this process, gasoline and fuel oil are generated as by-products. 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) This report was developed based essentially on the following reference(s): US Patent 4242531, issued to Phillips Petroleum Company in 1980 Keywords: Olefins Dimerization, Ethene, Butylene, n-Butene, 2-Butene, Loop Reactor
