Abstract: Apparatus for remediation of particulate matter and gaseous pollutants entrained in flue gases. The flue gases, having a pre-determined moisture content, are mixed with sorbent material and forced through an induct venturi equipped with a mixing impeller. Downstream, the reaction products are removed from the gas stream and collected for use as construction material. The vented gas stream is monitored for specific pollutants and the amount of sorbent material introduced into the system can be automated in response to reading obtained. Additionally, the gas stream can pass through a bag house or cyclone wherein the bags are impregnated with materials specific to the pollutants carried in the stream.
