IAC Recirculating Dry Scrubber 2009 Patent
The present invention provides improved boiler assemblies (10) with enhanced pollution abatement properties through injection and recycling of particulate sorbent materials including sodium bicarbonate, trona, and mixtures thereof. The assemblies (10) include a boiler (12), economizer (14), air heater (15), and recirculation reactor (16). Fresh sorbent material is introduced via assembly (60) into the boiler assembly (10) at one or more injection locations, and serves to sorb NOx, SOx, and other pollutants in the flue gas. The flue gas and entrained sorbent material then pass through reactor (16) for separation of sorbent, which is then recycled for injection back into the assembly (10) upstream of reactor (16). The present invention can also be used in industrial applications where the same emissions are generated and are needed to be controlled. Examples of such applications are Cement and Lime Kilns.

Dry FGD By-Product Characteristics and Utilization - Fujian Longking
No one area of the world has a monopoly on dry scrubber knowledge. The reality is that China, with hundreds of dry scrubber installations, has accumulated knowledge which puts it on equal footing with the U.S., European, and Japanese companies which originally brought the dry scrubbing technology to China.

Mike Widico and Kevin Cosman of KC Cottrell presented a number of positive features about their design. It is compact and even with the cyclone can be fitted into most power plants. Because of the cyclone to capture the calcium sulfate, the downstream precipitator is not contaminated by large quantities of high resistivity dust.

Gas Suspension Absorber / Description
One of the reasons for the high efficiency of the KC Cottrell GSA is that the reactor has been based on gas suspension technology. This means that a very large concentration of fly ash, dust particles and lime builds up inside the reactor. The concentration is normally 50 to 100 times as high as in a conventional reactor. The effect is further enhanced by the fact that lime, fly ash and by-products are recycled about 100 times in the KC Cottrell GSA system. A short erection period is achieved due to a modular design, offering enormous flexibility. Maintenance costs for the KC Cottrell GSA are extremely low compared to more conventional plants. One reason for this is the minimal wear and tear due to few moving parts and a very simple, uncomplicated and stationary nozzle.

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
