Patent ID: 7297182

Claim:
A method for removing particulate matter and scrubbing toxic gases from a biomass derived gas stream, the method comprising: introducing a contaminated biomass derived gas stream into a housing; spraying a fine liquid mist into the contaminated gas stream; electrically charging particulates and droplets in the gas stream by passing the gas stream by at least one ionizing electrode in a Wet Electrostatic Precipitator (WESP) section; collecting the electrically charged particulates and droplets on a collecting surface draining the collected electrically charged particulates and droplets into a scrubbing section; scrubbing the electrically charged particulates from the gas stream in a scrubbing section; and changing the direction of the gas stream when it moves from the WESP section to the scrubbing section and when it moves from the scrubbing section to the WESP section.
