  • Patent number: 5186728
    Abstract: An apparatus for preventing or reducing the release of volatile organics in the atmosphere that comprises a distributor cup having holes located on the bottom surface of the cup and a vent tube that passes through the cup. The cup is attached to a scrubber body containing inert, solid material held in place by a slotted support plate. A dip-tube extends downwardly from the scrubber body. The invention includes a process that comprises passing water through a distributor cup having holes at the bottom of the cup, allowing water to trickle onto solid, inert material in the scrubber body to produce film on the material and on the internal surfaces of a dip-tube extending from the scrubber body so that vent gases can be scrubbed, and these scrubbed vent gases exit through a vent tube that passes through a distributor cup.
