Sulfur contained in the coal is an element impurity apart from other contaminants such as ash, soil, rocks, and minerals. The combustion of high sulfur from coal produces SO2 which can interfere the human health, such as causing tightness in the respiratory tract, as well as the environment by causing acid rain and corrosion on plant equipment.

COAL EXTRACTION AND PROCESSING

COAL EXTRACTION AND PROCESSING

the process of subsurface coal extraction and thermal coal processing. Purpose Coal is used for its potential heat energy when burned and since the 1880s has been widely used to generate electricity in power plants. To to generate electricity coal is first burned inside a power plant and the heat generated by the coal is then used to heat water.

The microbial desulfurization of coal

Inorganic sulfur consists mostly of iron sulfides, the socalled "pyritic sulfur," whereas organic sulfur is covalently bound to the carbon atoms of the coal macromolecule. Comminution of coal to sizes that liberate the iron sulfide grains makes their removal with mineral beneficiation processes theoretically possible, but practically profitless.

Desulfurization of Coal

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, inbed desulfurization, and flue gas desulfurization. Coal .
