Filtration - Wikipedia

Filtration is used to separate particles and fluid in a suspension, where the fluid can be a liquid, a gas or a supercritical fluid. Depending on the application, either one or both of the components may be isolated. Filtration, as a physical operation is very important in chemistry for the separation of materials of different chemical composition.

Coalpail.com - Anthracite Coal (Hard Coal)

The primary use for anthracite is as a home heating fuel, other uses include water filtration, as a coking product and other industrial uses. Compared to bituminous coal anthracite has some very distinct advantages for home heating. Because of the low volatile content it will burn up to fine powdery ash.

Carbon filtering - Wikipedia

Carbon filtering is a method of filtering that uses a bed of activated carbon to remove contaminants and impurities, using chemical adsorption.. Each particle, or granule, of carbon provides a large surface area, or pore structure, allowing contaminants the maximum possible exposure to the active sites within the filter …

11.10 Coal Cleaning - US EPA

11.10 Coal Cleaning 11.10.1 Process Description1-2,9 Coal cleaning is a process by which impurities such as sulfur, ash, and rock are removed from coal to upgrade its value. Coal cleaning processes are categorized as either physical cleaning or chemical cleaning. Physical coal cleaning processes, the mechanical separation of coal from its

Management of Coal Preparation Fine Wastes Without ...

Fine coal refuse settled solids and filter cakes exhibit low permeabilities in the order of 10~5 to 10"' cm/sec. 9. Fine coal refuse settled solids and filter cakes do not possess significant cohesive strengths, /~1 psi. 10. Fine coal refuse slurries may be considered incom- pressible and exhibit virtually no rebound after the compressive load ...

Improved Techniques for Hyperbaric Filtration of Fine Coal ...

Dewatering of fine clean coal slurry is one of the most important unit operations of a coal-cleaning circuit. However, an efficient and economic dewatering method is still eluding the coal industry. In this study hyperbaric (high pressure) filtration studies were conducted on a froth flotation product obtained from a coal preparation plant processing Pittsburgh No. 8 seam coal.
