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

Book Description

This report presents a cost analysis of Sodium Hydroxide 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 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) Handbook of Chlor-Alkali Technology, 2005 (2) "Chlorine," Ullmann's Encyclopedia of Industrial Chemistry, 7th edition Keywords: Chlor-Alkali, Caustic Soda, NaOH

Book Description

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

Book Description

This report presents a cost analysis of Precipitated Calcium Carbonate (PCC) 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): Keywords: Hydrated Lime, Slaked Lime, Slake, Calcium Oxide, Lime-Soda Process

Book Description

This report presents a cost analysis of Calcium Hypochlorite production from slaked lime, sodium hydroxide and chlorine The process examined is a typical sodium process. This process consists mainly in passing chlorine into a slurry of slaked lime and sodium hydroxide, generating Calcium Hypochlorite and sodium chloride. After separation steps, Calcium Hypochlorite (about 70 wt%) and an aqueous solution of sodium chloride are obtained as products. This report was developed based essentially on the following reference(s): (1) US Patent 4390512, issued to PPG Industries, Inc., in 1983 (2) US Patent 4428919, issued to PPG Industries, Inc., in 1984 Keywords: Caustic Soda, Calcium Salt, Bleaching Powder, Chlorination, Sodium Method, Slaked Lime

Book Description

This report presents a cost analysis of Epichlorohydrin production from propylene and chlorine. The process examined is a typical dehydrochlorination process. This process involves three main steps: (i) chlorination of propylene to allyl chloride; (ii) addition of hypochlorous acid to the allyl chloride formed yielding glycerol dichlorohydrins, and (iii) treatment of the glycerol – dichlorohydrin mixture with a base, yielding Epichlorohydrin product. 99.9 wt.% Epichlorohydrin is obtained. This report was developed based essentially on the following reference(s): Rowe, C.E., 'Chlorohydrins', Chemical Processing Handbook, 1993 Keywords: 3-Chloropropene, Hypochlorous Acid, HOCl, Chlorination
