Dry sorbent injection (DSI)

In the DSI system, calcium or sodium-based alkaline sorbents are injected into the flue gas to remove acid gases (SO2,SO3/H2SO4, HCl), volatile organic compounds (VOCs), and metals (Hg, …). Injection of the sorbent is simple and takes place between the air heater and the PM control equipment.
