Filed:

Aug 8, 2007

Appl. No.:

11/835890

Inventors:

Michael D. Durham - Castle Rock CO, US
Cameron E. Martin - Denver CO, US

Assignee:

ADA Environmental Solutions, LLC - Littleton CO

International Classification:

B01D 53/64
B01D 53/06

US Classification:

95107, 95131, 95134, 110345

Abstract:

A system for treating a contaminated gas stream is provided that includes a comminution device operable to effect size reduction of a plurality of sorbent particles and form a plurality of comminuted particles, a plurality of nozzles distributed through the gas stream and operable to introduce the plurality of comminuted particles into the gas stream, and a particle removal device operable to remove at least most of the introduced comminuted particles and form a treated gas stream. The comminution device is in direct fluid communication with the nozzles.

International Classification:

B03C 3013

US Classification:

95 71

Abstract:

The present invention discloses a process for removing undesired particles from a gas stream including the steps of contacting a composition containing an adhesive with the gas stream; collecting the undesired particles and adhesive on a collection surface to form an aggregate comprising the adhesive and undesired particles on the collection surface; and removing the agglomerate from the collection zone. The composition may then be atomized and injected into the gas stream. The composition may include a liquid that vaporizes in the gas stream. After the liquid vaporizes, adhesive particles are entrained in the gas stream. The process may be applied to electrostatic precipitators and filtration systems to improve undesired particle collection efficiency.
