Packed beds are most commonly used in air pollution control, but they are also used in the chemical, In a venturi scrubber, contact between a high velocity gas and a free-flowing liquid causes the gas contaminants to be trapped in liquid droplets. They also capture airborne dust in the processing of a number of cereals. The process of UV absorption occurs in the skin and is eliminated by metabolism of the human body. The liquid stream flows through a liquid distributor and down the column due to gravity, resulting in counter-flow, cross-flow, or co-current flow.
