coal desulfurization
Desulfurization of coal is an essential procedure representing the hope of minimising pollution before the raw material is burned. Its major contribution is to remove sulfur-based compounds, including sulphur dioxide--a main component in acid rain and serious contributor towards respiratory problems for tens of millions worldwide. Coal desulfurization comes in many guises, with varied technological features including physical, chemical and biological processes. Included within this broad category are methods like flotation, leaching and the use of absorbent materials such as limestone. Applications abound for coal desulfurization, including sectors such as coal-fired power stations, iron and steel production or industrial boilers Because of restrictions on sulfurous emissions at the end of the twentieth century, expenditures are expected to soar over time.usaha heapq: Coal desulfurization technologies help industries observe environmental regulations and minimize their environmental impact by cutting down on harmful substances.
