A gas absorption system is disclosed. The system comprises a vertical housing having a plurality of superposed absorption stages, each stage comprising a ball bed, a plurality of venturi tubes located below the ball bed through which gas is circulated upwardly from stage to stage, a piping system for circulating an absorption liquid at each stage, the level of the absorption liquid in each stage being maintained by overflow from stage to stage, a nozzle connected to the piping system and centered over each venturi tube pointing upwardly into the ball bed for spraying absorption liquid into the ball bed to react the gas circulated through each stage with the absorption liquid, and a cap for capping each venturi tube to prevent the absorption liquid from dripping from stage to stage through the venturi tubes. Each cap includes gas openings allowing gas to flow upwardly from stage to stage to be reacted with the absorption liquid in the ball bed of each stage. |
