coking coal washability tests removing sulphur

Float-Sink (Washability) Test, Coal Analysis, Kentucky

Jul 27, 2020· Float-sink tests are done on samples of coal from beds that will likely need washing (beneficiation, preparation) to remove sulfur or ash (rock and mineral matter) from the coal to meet the desired specifications of the end user.The float-sink analysis determines how much coal can be separated from rock and minerals in fluids of different densities.

Coking Coal an overview ScienceDirect Topics

The coal required for these purposes is a vitrinite-rich coal with a certain proportion of inertinite (to add strength to the walls of the coke); it is required to have low ash content (< 12%), low sulphur (< 1%) and phosphorus content (< 0.001%) and most importantly requires a coal with a maturity that falls in the mid bituminous level

DETERMINATION OF THE WASHABILITY OF ENUGU COAL

The physical properties of coking coal cause the coal to soften, liquefy and then resolidify into hard but porous lumps when heated in the absence of air. Coking coal must also have low sulphur and phosphorous contents. Almost all metallurgical coal is used in coke ovens. The coking process consists of heating coking coal to around 1000-1100ºC

Washability an overview ScienceDirect Topics

The behavior of coal in density-based cleaning processes can be predicted from a series of float-sink (or washability) tests carried out on a crushed sample in the laboratory.The sample is placed in a heavy liquid of known density (e.g., 1.40 g cm − 3) and the floating fraction skimmed off for weighing and analysis.The sinking fraction is then placed in a liquid of somewhat higher density

Study on dielectric properties of high organic sulfur

Jan 03, 2019· Coking coal is geologically scarce resource and most of them cannot be directly used in steel making due to their higher sulfur content. One desulfurization method that has great potential for massive application is microwave desulfurization, which removes the relatively stubborn organic sulfur under mild conditions. The dielectric properties of coals determine the efficiency of the microwave
