Description:
The paper gives results of the measurement of liquid entrainment rate and drop size distribution in the exhaust gas stream from a mobile bed scrubber. The pilot plant scrubber was 46 cm square and was packed with 3.8 cm diameter hollow polyethylene spheres to a static depth of 25 cm. Entrainment flow depends on both gas and liquid rates. At a liquid/gas ratio of 6.7 l/cu m and a superficial gas velocity of 2.6 m/sec, the entrainment flow rate was 0.0064 l/cu m; at 3.75 m/sec, it was 0.031 l/cu m. The mass median drop diameter was about 400 micrometers at a liquid/gas ratio of 6.7 l/cu m. The drop size distribution appears to be bimodal. Dye impregnated paper and cascade impactor techniques were used to measure drop size.
