Mammoth

Deep anodes consist of parallel-connected single anodes which are set in boreholes 50 to 100 m deep with a diameter of 0.3 m. The boreholes can be produced by a variety of boring methods, but the air lift method has proved particularly suitable (see Fig. 9-10). The borehole is filled with water to ground level according to the principle of a mammoth pump. Compressed air is fed via a pipe to... [Pg.250]

A very sueeessful projeet began in the early 1980s when the Ben Holt Company (Pasadena, California) designed and eonstrueted a 10 MW air-eooled, elosed-loop binary eyele at their Mammoth Geothermal Plant, loeated on the eastern slope of the Sierra Nevada mountain range in California. [Pg.137]

The Mammoth-Paeifie plants are the world s first eommereial applieation ineorporating two elosed-loop systems (henee, binary proeess ) designed to proteet the environment and eonserve water. This is illustrated in Figure 4-43. [Pg.137]

Ethylene is the cornerstone of the world s mammoth petrochemical industry and is produced in vast quantities. In a typical year the amount of ethylene produced in the United States (5 x 10 ° lb) exceeds the combined weight of all of its people. In one process, ethane from natural gas is heated to bring about its dissociation into ethylene and hydrogen ... [Pg.189]

Manufacturers and specialist materials development associations publish extensive corrosion data in the form of monographs, and this form of presentation is also used in national standards. The most recent comprehensive text in this category is perhaps the publication by the Zinc Development Association . The work is important in that the section on chemicals also deals with common, though complex, chemical formulations, e.g. Are-extinguisher fluids, soaps and syndets, agricultural chemicals such as pesticides and fertilisers. This publication also demonstrates the mammoth task of recording all the available data for just one material. A comparable book for mild steel would probably be much larger, whereas for many other materials the information has not yet been determined. Thus at best, only very incomplete data are available in this form. [Pg.406]

I do not want to burden the Tribunal with tedious exposition, but we are concerned here with men who occupied key positions in a mammoth and intricate industrial establishment. In order to understand this case, it will be necessary to gain a general knowledge of the history and structure of the Farben empire and how the defendants fitted mto the organization. [Pg.78]

In June 1977 in intact, completely frozen, baby wooly mammoth (named Dima) was uncovered by a bulldozer operation in the Magadan region of northeastern Siberia. A sample of 1.3 grams of muscle was made available to M. Goodman of the Anatomy Department of Wayne State University School of Medicine. At his request, a sample of about. 9 milligrams, obtained from 4 milligrams of muscle, was dated to have an age of 27,000 years. [Pg.64]

Oxidation is the first step for producing molecules with a very wide range of functional groups because oxygenated compounds are precursors to many other products. For example, alcohols may be converted to ethers, esters, alkenes, and, via nucleophilic substitution, to halogenated or amine products. Ketones and aldehydes may be used in condensation reactions to form new C-C double bonds, epoxides may be ring opened to form diols and polymers, and, finally, carboxylic acids are routinely converted to esters, amides, acid chlorides and acid anhydrides. Oxidation reactions are some of the largest scale industrial processes in synthetic chemistry, and the production of alcohols, ketones, aldehydes, epoxides and carboxylic acids is performed on a mammoth scale. For example, world production of ethylene oxide is estimated at 58 million tonnes, 2 million tonnes of adipic acid are made, mainly as a precursor in the synthesis of nylons, and 8 million tonnes of terephthalic acid are produced each year, mainly for the production of polyethylene terephthalate) [1]. [Pg.181]
