The report gives results of an evaluation of current technology relating to the separation of entrained drops of liquid from the gas leaving scrubbers. It includes results of experimental studies of entrainment separator characteristics, as well as theoretical analysis. Zigzag baffle, knitted mesh, tube bank, packed bed, and cyclone devices were tested. It reports collection efficiency and reentrainment as related to drop size. Pressure drop as a function of gas flow rate is also reported. Mathematical models from primary collection efficiency are satisfactory, but useful reentrainment models are not yet available. An auxiliary experiment was aimed at determining reentrainment from liquid sheets under the influence of an air stream. Work is still in progress on vertical gas flow systems, solids deposition, mathematical modeling, and the development of improved designs.
