Abstract

An emission treatment system includes a first separation device that is operable to introduce one or more sorbents into an exhaust stream having emission products. The sorbent captures the emission products such that the exhaust stream includes sorbent with captured emission products. A second separation device located downstream from the first separation device receives the exhaust stream and utilizes an electrostatic potential to separate the sorbent with captured emission products from the exhaust stream into a discharge stream to produce a clean stream.
