The Packed Bed Scrubber, or Packed Tower, is designed to remove gaseous or vaporous pollutants from an air stream. The process is accomplished by contacting the contaminated air stream with a scrubbing liquor that absorbs or chemically reacts with the pollutants. Some vapors can be simply removed by condensation through the cooling effect of the circulating liquid. The cleaned air is then discharged to the atmosphere and the contaminated scrubbing liquor is either disposed of in an approved manner or chemically treated and recycled. In some cases, the collected contaminants can be recovered and reused in the original or other processes.
How Packed Towers Work In order to optimize the contaminant removal efficiency, the contact between the contaminated air and the scrubbing liquor must be maximized. To achieve this, specially designed packing materials are used to fill the tower to a specified depth. The combination of packing material, packing design, depth of packing, bed velocity, and the scrubbing liquor chemistry and amount all combine to achieve the desired results. This is the science behind effective Packed Bed Scrubber design.
