2. Only pyritic sulfur is removable. The pyrite rejection is dependent to the particle size distribution of pyrite. small and highly disseminated pyrite particles are nearly impoosible to separate from coal. Desulfurization increases with grinding to finer sizes and with decreasing density of separating medium.
Nothing better exemplifies ESM''s hot metal desulfurization expertise than its state of the art magnesium based coinjection system. This system has been designed by ESM Group Inc., to ensure greater predictability of endpoint sulfur in the desulfurization of iron.
One of the most commonly used flue gas desulfurization (FGD) technologies for scrubbing pollutants from power plant gas emissions is a wet scrubber system. In this process, many pollutants end up in the circulating water in the scrubber. To maintain appropriate operating conditions, a constant purge stream is discharged from the scrubber system.
