Type Of Technologies Which Mining Companies Use To Minimize Sulfur Dioxide

For existing plants in rural areas, coal cleaning can reduce sulfur content of the coals used by about 40 percent. Advanced coal cleaning methods may be able to increase the amount of sulfur and ash removed but all of the processes are in their early stages of development and many may be high cost for the extra sulfur removal that is accomplished

    Source: www.ontario.ca, 2019 Solutions adapted to each situation. SO 2 emissions are proportional to feed sulphur content. If it is not feasible to reduce the amount of SO 2 released from the combustion process by switching to a burning product (mainly fuel) that has lower sulphur content, other options can be implemented.. For industrial companies, there are many solutions that take into

    Jun 02, 2016 SO 2 is the component of greatest concern and is used as the indicator for the larger group of gaseous sulfur oxides (SO x). Other gaseous SO x (such as SO 3) are found in the atmosphere at concentrations much lower than SO 2. Control measures that reduce SO 2 can generally be expected to reduce people’s exposures to all gaseous SO x. This
