The scheme used in physical coal cleaning processes varies among coal cleaning plants but can generally be divided into four basic phases: initial preparation, fine coal processing, coarse coal processing, and final preparation. A process flow diagram for a typical coal cleaning plant is presented in Figure 11.10-1.

Detailed Description. Coal tar is a byproduct of the coking, liquefaction, or gasification of coal. Coal-tar pitch is the residue that remains after the distillation of coal tar. Coal tar and coal-tar pitch are used in coal-tar-based sealcoat products, although use of coal-tar pitch is more common than use of coal tar. Both coal tar and coal ...

The coal preparation process is a physical cleaning process (Figure 3.3) [16]. The coal is first crushed to help liberate the mineral matter from the organic matter. Then the coal is screened into various size fractions. The type of screen employed depends on the size of coal being treated. Coal cleaning is accomplished in streams with coarse ...

The process described below concerns pot distillation using two stills, though tripple distilation was once the rule of the Scottish Lowland region and is still common in Ireland. In the next step, the mash is pumped into the first, copper still (called a wash still) and a raw spirit, the so-called 'low wines' at around 23% ABV, is produced.

The blended coal mass is heated for 12 to 20 hours for metallurgical coke. Thermal energy from the walls of the coke chamber heats the coal mass by conduction from the sides to the middle of the coke chamber. During the coking process, the charge is in direct contact with the heated wall surfaces and develops into an aggregate "plastic zone".
