Turbosorp® Circulating Dry Fluid Bed Scrubber

The Turbosorp® Circulating Dry Fluid Bed Scrubber is a cost-effective, highly efficient system designed to remove acid gas constituents, including SO2, SO3, HCl, HF, mercury, and other trace pollutants from flue gas streams. Turbosorp® is ideally suited for coals with sulfur contents below 3.0% with typical acid gas removal efficiencies greater than 97%. Turbosorp® is available for capacities up to 350 MWs per Turboreactor vessel. For plants larger than 350 MW, multiple reactor vessels are utilized.

The Turbosorp® dry scrubbing technology provides enhanced contact of finely atomized water, hydrated lime and flue gas through high levels of solid recirculation, within a fluid bed reactor. Lime and finely atomized water are injected independently into the Turboreactor to lower the flue gas temperature and enhance acid gas absorption capacity.

The fluid bed material is comprised of solids, including calcium hydroxide, fly ash from the combustion process, and solid reaction products recycled from the flue gas particulate collection device. Upon leaving the Turboreactor, the solid particles are separated from the flue gas in a fabric filter baghouse and recycled back to the reactor. Where mercury removal is required, Activated Lignite HOK® or carbon can be injected into the Turboreactor.
