Another dynamic iastmment, the Scentometer, is the basis for odor regulations ia the states of Colorado, Illinois, Kentucky, Missouri, Nevada, and Wyoming, and ia the District of Columbia (324). The portable Scentometer (Bameby-Cheney) can produce dilution ratios up to 128 1 ia the field. The Scentometer blends two air streams, one of which has been deodorized with activated carbon. The dilution ratio is decreased until the odor becomes detectable (325). Improvements to dynamic methods have been recommended (326). 

The ores of most importance are fluorspar, CaF2 fluorapatite, Ca (P0 2Fj cryoHte [15096-52-3], Na AlF. Fluorspar is the primary commercial source of fluoiine. Twenty-six percent of the world s high quaHty deposits of fluorspar are ia North America. Most of that is ia Mexico. United States production ia 1987—1991 was 314,500 metric tons, most of which occurred ia the Illinois-Kentucky area. Imported fluorspar ia 1990—1991 represented about 82% of U.S. consumption 31% of U.S. fluorspar imports were from Mexico and 29% from China compared to 66% from Mexico ia the 1973—1978 period. The majority of the fluorine ia the earth s cmst is ia phosphate rock ia the form of fluorapatite which has an average fluorine concentration of 3.5%. Recovery of these fluorine values as by-product fluorosiHcic acid from phosphate production has grown steadily, partially because of environmental requirements (see Phosphoric acid and THE phosphates). 

Fluorspar occurs in two distinct types of formation in the fluorspar district of southern Illinois and Kentucky in vertical fissure veins and in horizontal bedded replacement deposits. A 61-m bed of sandstone and shale serves as a cap rock for ascending fluorine-containing solutions and gases. Mineralizing solutions come up the faults and form vein ore bodies where the larger faults are plugged by shale. Bedded deposits occur under the thick sandstone and shale roofs. Other elements of value associated with fluorspar ore bodies are zinc, lead, cadmium, silver, germanium, iron, and thorium. Ore has been mined as deep as 300 m in this district. 

The decrease in petroleum and natural gas reserves has encouraged interest in and discovery and development of unconventional sources of these hydrocarbons. Principal alternatives to conventional petroleum reserves include oil shale (qv) and tar sands (qv). Oil shale reserves in the United States are estimated at 20,000 EJ (19.4 x 10 Btu) and estimates of tar sands and oil sands reserves are on the order of 11 EJ (10 x 10 Btu) (see Tarsands Shale oil). Of particular interest are the McKittrick, EeUows, and Taft quadrangles of Cahfomia, the Asphalt Ridge area of Utah, the Asphalt, Kentucky area, and related geographic regions. 

In 1976, Ashland Od (Ashland Synthetic Fuels, Inc.) was awarded the prime contract to constmct a 540 t/d H-coal pdot plant adjacent to its refinery at Cadettsburg, Kentucky, by an industry—government underwriting consortium. Constmction was completed in 1980 (112). The pdot-plant operation ended in eady 1983. 

Properties. A high volatile western Kentucky bituminous coal, the tar yield of which by Fischer assay was ca 16%, gave a tar yield of ca 26% at a pyrolysis temperature of 537°C (146—148). Tar yield peaked at ca 35% at 577°C and dropped off to 22% at 617°C. The char heating value is essentially equal to that of the starting coal, and the tar has a lower hydrogen content than other pyrolysis tars. The product char is not suitable for direct combustion because of its 2.6% sulfur content. 

With the beginning of the industrial revolution around 1800, oil became increasingly important for lubrication and better illumination. Expensive vegetable oils were replaced by sperm whale oil [8002-24-2], which soon became scarce and its price skyrocketed. In 1850 lubrication oil was extracted from coal and oil shale (qv) in England, and ultimately about 130 plants in Great Britain and 64 plants in Pennsylvania, West Virginia, and Kentucky employed this process. 

There were 113 commercial and captive lime plants in the United States as of 1993. Of these plants, the 10 largest produce about 35% of total lime output. Ohio is the largest lime producing state, followed by Peimsylvania, Missouri, Kentucky, Alabama, Texas, Illinois, Indiana, Virginia, and Arizona. 

Manufacture. There are two main 2-pyrroHdinone producers. International Specialty Products (ISP) (GAF Corporation) has manufacturing facihties in Calvert City, Kentucky, and Texas City, Texas, and BASF manufactures it at Ludwigshafen, Germany. Both producers consume most of thek production in the manufacture of l-vinyl-2-pyrrohdinone.

In the 1880s and 1890s, whiskey production grew significantiy. Excessive production and intense competition resulted in mergers such as the Whiskey Tmst in Peoria and the Kentucky Distilleries and Warehouse Companies. They attempted to control production and raise prices but had tittle success in doing so.

Reactions of Goal Ash. Mineral matter impurities have an important effect on the utili2ation of a coal. One of the constituents of greatest concern is pyrite because of the potential for sulfur oxide generation on combustion. The highest concentrations of pyrite are associated with coal deposition under marine environments, as typified by the Illinois Basin, including parts of Illinois, Indiana, and Kentucky. Additionally, the mineral matter... 

Hydrauhc transport is used in mines and for lifting coals to the surface in Russia, Poland, and France. Pneumatic transport of coal is used over short distances in power plants and steel mills. The longest (14.5 km) single flight conveyer belt in the world near Uniontown, Kentucky, has a capacity of 1360 t/h. 

One significant advantage of pulverized coal boilers is the ability to use any kind of coal, including mn-of-mine or uncleaned coals. However, with the advent of continuous mining equipment, the ash content frequently is ca 25%, and some preparation is frequently practiced. There were 931 coal preparation plants in the United States in 1988, mainly in Kentucky, West Virginia, and Peimsylvania. 

Several processes progressed to demonstration scales but have not been commercialized, primarily because of economic inabiHty to compete with available petroleum products. The H-Coal process developed by Hydrocarbon Research, Inc. was demonstrated at Catiettsburg, Kentucky using a 545 t/d plant and DOE support. The Exxon donor solvent Hquefaction process was not commercialized either.
