Chloroprene Production from Butadiene - Cost Analysis - Chloroprene E11A

This report presents a cost analysis of chloroprene production from butadiene and chlorine. The process examined is a typical vapor phase butadiene chlorination process. In this process butadiene is first chlorinated producing two chlorinated isomers, 1,4-dichloro 2-butene and 3,4-dichloro 1-butene. In a second step, 1,4-isomers are isomerized to 3,4-dichloro 1-butene. This chemical is then dehydrochlorinated in the presence of caustic soda producing chloroprene and sodium...

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: Dupont, Chloroprene Rubber, Neoprene, Chlorination
