Title:
METHOD TO CONTROL PARTICULATE MATTER EMISSIONS
Document Type and Number:
WIPO Patent Application WO/2012/039826
Kind Code:
A3
Abstract:
A method for removing particulate matter from a particulate-bearing gas stream comprises flowing a particulate-bearing gas stream at a first volumetric flow rate to a plurality of ESP units; producing electrically charged particulate matter; collecting electrically charged particulate matter on collection electrode plates; reducing the flow through at least one of the ESP units; sequentially increasing the flow through one or more remaining ESP units in an amount so as to maintain the sum of flow through all of the ESP units at the first volumetric flow rate; subjecting the collection electrode plates in the at least one ESP unit with reduced flow to forces which dislodge the particulate matter from the collection electrode plates; collecting the dislodged particulate matter in a particulate collection receptacle; and withdrawing a gas stream of reduced particulate matter contamination.
