Sodium Hydroxide Via Membrane Process Cost Analysis Sodium Hydroxide E11a

This report presents a cost analysis of Sodium Hydroxide production from brine. The process examined is a typical membrane process. In this process, an aqueous solution of sodium chloride (brine) is decomposed electrolytically in a membrane cell, producing Sodium Hydroxide and chlorine. The Sodium Hydroxide product obtained is a 50 wt% aqueous solution. Hydrogen is also generated as by-products in the process. 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): "Chlorine", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition Keywords: Chlor-Alkali, Caustic Soda, NaOH

This report presents a cost analysis of caustic soda flakes production from a caustic soda solution (50 wt%). In this process, caustic soda is concentrated to about 99 wt% in a specially designed evaporator and the resulting melt is fed by gravity to a flaking machine, where it is cooled and processed into flakes. This report was developed based essentially on the following reference(s): "Sodium Hydroxide", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition Keywords: Chlor-Alkali, Caustic Soda, NaOH, Caustic Flakes

This report presents a cost analysis of Sodium Hydroxide production from brine. The process examined is a typical diaphragm process. In this process, an aqueous solution of sodium chloride (brine) is decomposed electrolytically in a diaphragm cell, producing Sodium Hydroxide and chlorine. The Sodium Hydroxide product obtained is a 50 wt% aqueous solution. Hydrogen is also generated as by-products in the process. This report was developed based essentially on the following reference(s): (1) "Chlorine", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition (2) EP Patent 1427871, issued to Industrie De Nora in 2011 Keywords: Chlor-Alkali, Caustic Soda, NaOH

This report presents a cost analysis of Chlorine production from sodium chloride. The process examined is a typical membrane process. In this process, an aqueous solution of sodium chloride (brine) is decomposed electrolytically in a membrane cell, producing Chlorine. Caustic soda (50 wt%) and hydrogen are also generated as products. This report was developed based essentially on the following reference(s): (1) Handbook of Chlor-Alkali Technology, 2005 (2) "Chlorine", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition Keywords: Chlor-Alkali, Caustic Soda, NaOH

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

Since first AC current high-power hydropower plant was put in operation, built by Nikola Tesla and George Westinghouse in 1895 on Niagara Falls, electrification of the world has dramatically changed. The growing power demand and energy consumption in the last decades require fundamental changes in the process, power production, and services. These requirements tend to use both conventional and nonconventional energy generation in order to have power plants economically useful and environmentally friendly to the society. The goal of this textbook is to provide an up-to-date review of this important topic with specific emphasis on the current guidelines for improving overall efficiency, lowering emissions, and using large share of renewable energy.
