Abstract:
1. A method for reducing contaminant emissions from a combustion source, comprising: receiving from an exhaust tube an exhaust stream emitted by the combustion source, the exhaust stream including particulate material and noxious gases; injecting an aqueous liquid into the exhaust stream, thereby increasing the humidity and elevating the temperature of the dewpoint; cooling the exhaust stream by passing the exhaust stream through a plurality of tubes to at least partially condense the exhaust stream to produce a liquid extraction stream and a residual gaseous stream, the liquid extraction stream comprising the particulate material, the aqueous liquid condensed on the particulate material, and the noxious gases dissolved in the condensed aqueous liquid; and collecting the condensed extraction stream.
