Control of mercury emissions from stationary coal

2016-11-1 · The mercury removal efficiency of coal washing varies largely from 10 to 90%, and the remaining mercury is primarily bound to the organic matter and sulfide minerals (Streets et al., 2005, Yudovich and Ketris, 2005). It has been estimated that coal washing removes, on the average, 30% of the mercury from raw coals in China (Streets et al., 2005). Besides lowering mercury emissions, the
