ABSTRACT:
An apparatus is provided for recovering the particles entrained in a vaporous vent by passing the vent into a scrubber which uses as scrubbing liquid a liquid in which the particles are buoyant, maintaining a liquid level of scrubbing liquid in the base of the scrubber with overflow of floating polymer particles and scrubbing liquid from the surface of the liquid level. The particles can be passed back to the tank from which the particles were originally vented. A scrubbed, particle-free, vent gas is removed from the top of the scrubber and the scrubbing liquid can be recycled from the base of the scrubber for recontact with the vaporous vent containing particulate matter.
