REDUCTION OF PARTICULATES IN GAS STREAMS

Title:

REDUCTION OF PARTICULATES IN GAS STREAMS

Document Type and Number:

WIPO Patent Application WO/2012/009189

Kind Code:

A4

Abstract:

This invention provides methods for reducing a spark rate and/or increasing the voltage in a cold-side electrostatic precipitator through which a particulate-containing gas stream is directed, wherein said electrostatic precipitator has a spark rate and a voltage. The methods comprise injecting an amount of a halogenated carbonaceous substrate formed from a carbonaceous substrate and an elemental halogen and/or a hydrohalic acid into the particulate-containing gas stream upstream of the electrostatic precipitator, such that the spark rate decreases by about 40% or more and/or such that the voltage can be increased by about 20% or more than when said halogenated carbonaceous substrate is not injected.
