Sulfur Removal Process From Coal Briquette Mining

Sulfur Removal At High Temperature During Coal Combustion. Jan 01 2003 simply blending limestones with feed coal at cas2 only gives a low sulfur removal efficiency of 1520 during coal combustion on grates which cannot meet the current requirements of so 2 emissions this is mainly because of the thermal instability of sulfation products above 1200 c and the long duration about 1 h in the coal

Removal of sulfur compounds from combustion product

A process for the simultaneous removal of sulfur oxides and nitrogen oxides from power plant stack gases comprising contacting the stack gases with a supported iron oxide catalyst/absorbent in the presence of sufficient reducing agent selected from the group consisting of carbon monoxide, hydrogen, and mixtures thereof, to provide a net reducing atmosphere in the SO.sub.x /NO.sub.x removal zone.

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. Optionally, the coal particles may be treated with a conditioning agent prior to the aggregation step.

COAL-FIRED POWER PLANTSSULFUR DIOXIDE REMOVAL

Nevertheless, it provides a proven method for removing high levels of the sulfur from a coal-fired power plant's flue-gas stream. A variation on the lime or limestone scrubbing system is the seawater FGD system. Instead of the calcium-based absorbents, this uses seawater pumped directly from the sea in the scrubbing tower to absorb sulfur
