Description:
The report gives results of the demonstration of the technical and economic feasibility of using an air curtain transport system to control buoyant fugitive particle emissions. (Fugitive emissions are the major source of uncontrolled emissions for many industrial plants. There are now no high performance, inexpensive control techniques available for many fugitive sources. A simple and inexpensive method is to divert the emissions with an air curtain into a control device located near the source.) A horizontal air curtain was used to capture and convey the buoyant fugitive particle emissions to a particle collection filter unit. High efficiency Particulate Air (HEPA) filters in the filter unit collected the particles. The air curtain capture efficiency, the measure of the air curtain's ability to capture and convey the fugitive emission plume, was between 63 and 105%, depending on air curtain slot exit velocity, and subject to + or - 18% error limit. The overall capture and containment efficiency of the pilot plant, when operating in the appropriate slot velocity range, can be expected to be between 90 and 99% when considered as a package.
