Gas Suspension Absorber Technology for Multi-pollutant Control of Boiler Flue Gas Emissions
A recirculating bed dry scrubber technology capable of efficient acid gas control –SO2, HCl, and H2SO4. •Utilizes lime reagent either as dry hydrate or as lime slurry. •Coupled with ESP or FF for control of PMand PM-10 emissions. •Can incorporate ACI for control of Hg and dioxins/furans. •Emissions of HCl, PM, Hg below MACT requirements.

Features and Benefits of KC Cottrell’s Gas Suspension Absorber (GSA) Technology
The lime can be injected either as a slurry, through commercially available two-fluid nozzle atomizers, or as powdered calcium hydroxide. The intense recirculation within the reactor promotes efficient acid gas neutralization, resulting in high removal efficiencies at low lime consumption rates. The nozzles are commercially available and can be changed out on the fly, without impacting scrubbing efficiency. The use of the cyclone to capture and recycle solids from the reactor vessel greatly reduces the demand on the downstream particulate collector. The slim profile of the GSA reactor vessel itself minimizes plan area requirements, which are frequently at a premium in retrofit applications

John Buschmann, Technology Manager at ALSTOM Power Inc., provided an overview of the proposed Utility MACT emission values and discussed the implications for utilities seeking compliance not only under Utility MACT but also under CSAPR and various other existing and anticipated regulations. The solution is not a one-size-fits-all approach but rather a careful balancing of combinations of AQCS technologies that make up an overall compliance plan.
