How to Remove Sulphur from Coal

The process effectively removed over 95 percent of the pyritic sulfur in the coal. Reclamation of pyritic sulfur would eliminate stream pollution by acid water drainage and other environmental problems.

US4270926A - Process for removal of sulfur and ash from ...

A process for reducing the sulfur and ash content of coal wherein coal particles are treated in an aqueous slurry with a minor amount of hydrocarbon oil to form coal-oil aggregates. The coal-oil aggregates are separated from ash and mineral matter in the slurry by dissolved gas flotation.

Physical removal of pyritic sulfur from coal before combustion, limestone (CaCO 3) addition to the combustor to absorb sulfur oxides during combustion, using flue-gas scrubbers to remove sulfur oxides from plant gas emissions after combustion, conversion of the coal to low-sulfur clean fuel by gasification or liquefaction, and fuel switching, or blending of high sulfur coals with low sulfur coals…

New technology removes sulfur from coal

New technology removes sulfur from coal. The test results showed that the process can remove 85 to 95 percent of the pyrite from high-sulfur coals. An advantage of the process is that it works without coal grinding, a step that is necessary to achieve high levels of sulfur rejection using only flotation devices.

The cleaning removes impurities like rock, ash, sulfur and other substances. A high amount of rock and clay particles reduces the quality and heating value of coal and usually means a lower price for coal. Some coal is crushed and mixed with water and transported through pipelines. Coal processing involves crushing, screening and beneficiation.

Desulfurization of Coal

In coal combustion, to generate electric power and process heat, the sulfur is emitted as SO2, which is seen as one of the main causes of acid rain. This effect has led to an interest in the three main methods of removing coal sulfur: coal cleaning, in-bed desulfurization, and flue gas desulfurization. Coal cleaning includes physical, chemical,

Sulfur removal by fine coal cleaning processes - ScienceDirect

Abstract. The reduction in sulfur emission value that can be achieved depends on the sulfur liberation characteristics of the feed material. The emission value of a high-sulfur (2.86 wt%) run-of-mine coal was reduced from 1321 to 881 g of sulfur per GJ: a …

Process for removing sulfur from coal(Patent) | DOE Patents

A process for the removal of divalent organic and inorganic sulfur compounds from coal and other carbonaceous material. A slurry of pulverized carbonaceous material is contacted with an electrophilic oxidant which selectively oxidizes the divalent organic and inorganic compounds to trivalent and tetravalent compounds.
