Abstract:
1. An emission treatment system comprising: a first separation device operable for introducing at least one sorbent into an exhaust stream having emission products, the at least one sorbent for capturing the emission products such that the exhaust stream includes sorbent with captured emission products; a second separation device downstream from the first separation device for receiving the exhaust stream and establishing an electrostatic potential to separate the sorbent with captured emission products from the exhaust stream into a discharge stream to produce a clean stream; a recycle passage between the first separation device and the second separation device for recirculating at least a portion of the at least one sorbent, the recycle passage including a regenerator for regenerating sorbent with captured emission products and producing regenerated sorbent; and a controller in communication with at least the first separation device and the regenerator, and the controller is configured to control a rate of introduction of the at least one sorbent into the first separation device and a rate of introduction of regenerated sorbent from the regenerator into the first separation device.
