Chlorine Production from Hydrogen Chloride - Cost Analysis - Chlorine E21A


Book Description

This report presents a cost analysis of secondary Chlorine production from hydrogen chloride. The process examined is similar to the Kel-Chlor process, proprietary technology based on the Deacon process. In this process, anhydrous hydrogen chloride is subjected to an oxidation reaction in the presence of catalysts producing Chlorine. 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: Secondary chlorine, hydrogen chloride waste treatment, HCl, cholrine recovery

Book Description

This report presents a cost analysis of Sodium Hydroxide production from lime and sodium carbonate. The process examined is a conventional lime-soda process. In this process, calcium hydroxide is generated by treating lime (calcium oxide) with water. Then, calcium hydroxide reacts with soda ash (sodium carbonate) forming sodium hydroxide and Calcium Carbonate. Precipitated calcium carbonate, in solid form, and Sodium Hydroxide solution (50 wt%) are obtained as final products. This report was developed based essentially on the following reference(s): Hou, T.P., "Manufacture of Soda: With Special Reference to the Ammonia Process", 1942 Keywords: Hydrated Lime, Slaked Lime, Slake, Calcium Oxide, Lime-Soda Process




Polychloroprene Production - Cost Analysis - CR E21A


Book Description

This report presents a cost analysis of Chloroprene Rubber (also known as Polychloroprene) production from butadiene and chlorine. 'The process examined is a typical vapor phase butadiene chlorination process, followed by a typical emulsion polymerization 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 chloride. Finally, chloroprene is polymerized to form Polychloroprene. This report was developed based essentially on the following reference(s): (1) "Chloroprene", Kirk-Othmer Encyclopedia of Chemical Technology, 5th edition (2) "Polychloroprene", Kirk-Othmer Encyclopedia of Chemical Technology, 5th edition Keywords: Dupont, Chloroprene Rubber, Neoprene, Chlorination, Neoprene, Chloroprene Rubber, 2-Chlorobuta-1,3-Diene, Synthetic Rubbers
