Sodium Hydroxide via Lime-Soda Process - Cost Analysis - Sodium Hydroxide E21A


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




Calcium Carbonate Production from Lime - Cost Analysis - Calcium Carbonate E21A


Book Description

This report presents a cost analysis of Precipitated Calcium Carbonate (PCC) production from lime. In this typical process, lime reacts with water producing calcium hydroxide, which is further carbonated with carbon dioxide from calcination to produce PCC. This report was developed based essentially on the following reference(s): (1) US Patent 6251356, issued to G. R. International in 2001 (assigned to Pacific Nano Products in 2015) (2) US Patent 3920800, issued to Cyprus Mines Corporation in 1975 Keywords: Hydrated Lime, Slaked Lime, Slake, Calcium Oxide, Quicklime




Epichlorohydrin Production from Propylene - Cost Analysis - ECH E21A


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

Algae Based Polymers, Blends, and Composites


Book Description

Algae Based Polymers, Blends, and Composites: Chemistry, Biotechnology and Material Sciences offers considerable detail on the origin of algae, extraction of useful metabolites and major compounds from algal bio-mass, and the production and future prospects of sustainable polymers derived from algae, blends of algae, and algae based composites. Characterization methods and processing techniques for algae-based polymers and composites are discussed in detail, enabling researchers to apply the latest techniques to their own work. The conversion of bio-mass into high value chemicals, energy, and materials has ample financial and ecological importance, particularly in the era of declining petroleum reserves and global warming. Algae are an important source of biomass since they flourish rapidly and can be cultivated almost everywhere. At present the majority of naturally produced algal biomass is an unused resource and normally is left to decompose. Similarly, the use of this enormous underexploited biomass is mainly limited to food consumption and as bio-fertilizer. However, there is an opportunity here for materials scientists to explore its potential as a feedstock for the production of sustainable materials. - Provides detailed information on the extraction of useful compounds from algal biomass - Highlights the development of a range of polymers, blends, and composites - Includes coverage of characterization and processing techniques, enabling research scientists and engineers to apply the information to their own research and development - Discusses potential applications and future prospects of algae-based biopolymers, giving the latest insight into the future of these sustainable materials

Electronic Properties of Materials


Book Description

The present book on electrical, optical, magnetic and thermal properties of materials is in many aspects different from other introductory texts in solid state physics. First of all, this book is written for engineers, particularly materials and electrical engineers who want to gain a fundamental under standing of semiconductor devices, magnetic materials, lasers, alloys, etc. Second, it stresses concepts rather than mathematical formalism, which should make the presentation relatively easy to understand. Thus, this book provides a thorough preparation for advanced texts, monographs, or special ized journal articles. Third, this book is not an encyclopedia. The selection oftopics is restricted to material which is considered to be essential and which can be covered in a 15-week semester course. For those professors who want to teach a two-semester course, supplemental topics can be found which deepen the understanding. (These sections are marked by an asterisk [*]. ) Fourth, the present text leaves the teaching of crystallography, X-ray diffrac tion, diffusion, lattice defects, etc. , to those courses which specialize in these subjects. As a rule, engineering students learn this material at the beginning of their upper division curriculum. The reader is, however, reminded of some of these topics whenever the need arises. Fifth, this book is distinctly divided into five self-contained parts which may be read independently.
