Abstract |
The paper gives results of theoretical and experimental evaluations of the control of fugitive process emissions (FPE) with a Spray Charging and Trapping (SCAT) scrubber. Theoretical calculations showed that collection is better than 90% for all particle sizes. The SCAT uses an air curtain or jets to contain, convey, and divert the FPE into a charged spray scrubber. Experiments were performed on an 8000-cfm bench scale spray scrubber to verify the theory and feasibility of collecting fugitive particles with charged water spray. The results of the experiments and the comparison between theory and data are presented. The air curtain, developed for conveying the FPE to the spray scrubber, for collecting the crosswind, and containing hot buoyant plume, can achieve a smaller expansion angle and a lower entrainment rate than those reported in the literature. The design and air flow field for the air curtain are presented. The air curtain successfully deflected crosswind up to 15 mph and containing hot buoyant plume. At an air curtain/spray scrubber separation of 3 m, an air curtain with slot width of 5.1 cm and air exit velocity of 20 m/s can contain a hot plume rising at a velocity of 200 cm/s and has a temperature of 470C. |
