Reactivation and Recycling of Partially Utilized Sorbent Using a Novel OSU Process
The Ohio State University
posted on 04/06/2009
Researchers at the Ohio State University have developed a novel process for reactivation of partially utilized calcium-based sorbents for increased SO2 removal and sorbent utilization from coal-fired boilers/combustors. Limestone or hydrated lime used in pulverized or fluidized bed combustors for SO2 removal suffer from low reactivity and under-utilization as typically less than one-half of the available calcium is converted to a calcium sulfate product. The partially utilized sorbent is rendered ineffective for any further SO2 removal and is either disposed of or partially reactivated by hydration. Therefore, despite being economical and easily retrofittable in existing utility units, dry sorbent processes are less competitive with other more expensive SO2 control technologies due to their poor SO2 removal efficiency and low sorbent utilization. The increased sorbent utilization obtained by this reactivation process could significantly improve the sorbent-based flue gas desulfurization technology.
