Liquid Chromatographic Separation of Sediment, Rock, and

A method is described for the rapid fractionation of sediment, rock, and coal extracts and crude oils into compound classes. The method is based on combined polarity/affinity chromatography of soluble organic matter. Five heterocompound fractions are obtained in addition to the conventional saturated and aromatic hydrocarbon fractions. Model compound studies show that those fractions are

Coal preparation plant Wikipedia

A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.

PAPER OPEN ACCESS Development of dry coal gravity

Dry separation method was used at the beginning of 20th century to separate coal separation process. First industrial applications of dry separation took place in the middle of 1930s. At that time air separator Frazer-Yankey, based on aero suspension was used in in Pittsburgh and Lundale, West Wirginia coal preparation plants.
