Dry Sorbent Injection
Our dry sorbent injection (DSI) systems provide a low-cost solution to capture acid gases, either separately or combined, in coal-fired boilers (typically less than 300 MW), biomass boilers and industrial applications. On larger units, DSI systems also can be used for HCI or SO3 control when combined with other air emissions control technologies.
Our DSI systems provide up to 80% SO2 removal efficiency, and high HCl and SO3 removal efficiencies, and are designed to handle a variety of reagents including trona, sodium bicarbonate and hydrated lime.
