Tower Gas in Packing In scrubbers, a tower of packing material is used to increase the surface area of the gas-liquid contact region. As the gas stream moves through the tower, the liquid stream that removes contaminants interacts with it. By entering through Packed Tower Gas Scrubber Manufacturer tower the intake near the bottom and moving through the support plate and packed bed in the opposite direction as the scrubbing liquid flow, gas eliminates contaminants. After passing through the packed bed, the cleaned gas continues its journey towards the top of the tower through a mist eliminator section. In this case, any entrained liquid is removed before the pure air is released through the exit. These types of scrubbers work best when the gases being handled are clear of particles, as these have a tendency to clog the packing.
