Patent
·
OSTI ID:7101857
This patent describes a method. It comprises producing an exhaust gas stream from a diesel engine; adding a wetting agent to a water supply; contacting the exhaust gas stream with the water from the water supply having the wetting agent in a contact zone to produce a substantially water saturated exhaust gas stream; electrically charging particles and droplets in the water saturated exhaust gas stream in an ionizing zone; and electrostatically attracting and de-entraining soot and soot containing water droplets from the gas stream containing electrically charged particles and droplets in a collection zone to produce a substantially soot free exhaust gas stream.
