Book Description

This report presents a cost analysis of Styrene Butadiene Rubber (SBR) production via cold emulsion polymerization process. The process examined is a typical continuous cold emulsion process for producing a non-staining, non-oil extended SBR grade (similar to 1502). In this process, an emulsion comprising water, styrene and butadiene monomers is polymerized into a latex, which is then coagulated to form the styrene-butadiene rubber. 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): "Styrene-Butadiene Rubber", Kirk-Othmer Encyclopedia of Chemical Technology, 5th edition Keywords: Polymerization, Styrene Butadiene Rubber, eSBR, BD
