Mineral Commodity Report 20 - Clays
Clay, as a rock term, describes a soft, loose, earthy material containing particles with an average grain size of less than than 0.004 mm (4 mm) in the Wentworth grain size scale and less than 0.002 mm (2 mm) in most soil investigations. Clay is composed mostly of clay minerals, but may also contain quartz, feldspar, carbonates, ferruginous material, and other non-clay materials. All clays, apa...
متن کاملoeCUPATIONAL EXPOSURES lN PETROLEUM REFINING
Petroleum oil was used for many centuries in Egypt, China, Mesopotamia and Persia for heating, lighting, roadmaking and building. Small accumulations of oil were reported at Pechelbronn in Alsace in 1498 and in Poland in 1506, and Marco Polo noted 'oil springs' at Baku on the Caspian Sea in the latter part of the thirteenth century. Raleigh, in 1595, reported the existence of the Trinidad Pitch...
متن کاملWater Management in the Petroleum Refining Industry
Petroleum refining industry uses large volumes of water. The water demand is up to 3 m3 of water for every ton of petroleum processed (US EPA, 1980, 1982; WB, 1998). Almost 56% of this quantity is used in cooling systems, 16% in boiling systems, 19% in production processes and the rest in auxiliary operations. The water usage in the Mexican refineries is almost 155 millions m3 per year; it is 2...
متن کاملSynthesis, Characterization and Application of Al,Fe-Pillared Clays
Al,Fe-pillared clay was synthesized from domestic clay from Bogovina according to a common procedure: grinding, sieving, Na exchange, pillaring, drying and calcination. Two synthesized samples differing only in calcining conditions were prepared. Phase composition and textural properties of the starting clay and synthesized pillared clays were characterized using X-ray diffraction and physisorp...
