ABSTRACT:
A gas trap for removing pollutants from gases which includes a vertically disposed, hermetic, double bulb enclosure wherein said bulbs are connected by a restricted passageway. A bubble tube that terminates in a fritted lower end is centrally disposed within said enclosure and extends adjacent to the bottom thereof. The enclosure is filled to approximately the midpoint of the upper bulb with pollutant reactant which removes selected pollutants from gases bubbled through the trap. In the method a polluted gas enters the bubble tube and exits the fritted end as bubbles which rise through the reactant solution to the restricted passageway. There, the rising gas is delayed due to the reduced cross-section of the enclosure and thus remains in contact with the reactant longer than if the flow path were unrestricted. The additional contact time between the polluted gas and the reactant allows more pollutant to be absorbed by the solution, thereby enhancing the trapping process. The size of the holes in the fritted material and the degree of restriction of the flow path are adjusted to substantially prevent back pressure from occurring in the system which would impede the flow of the gas being treated, but still allow virtually complete absorption of the pollutant by the reactant solution.
