PACKED BED SCRUBBER

Shimi Research Center Pvt Ltd is a leading Packed Bed Scrubber manufacturer in India. Packed Bed Scrubbers are highly effective for removing soluble chemicals, fumes, and odors. We supply packed bed scrubbers in different parts of the world which are manufactured from export quality raw materials. At present we are one of the leading exporters of Packed Bed Scrubbers to South Africa and Middle East countries such as UAE and Saudi Arabia. Our engineering staff is capable of providing you with equipment integrating all aspects of your air pollution control requirements.

The Packed Bed Scrubber, or Packed Tower, is designed to improve contact between two phases in a chemical process by having one or more beds of solid packing material. Packing offers the advantage of a lower pressure drop across the tower, which is beneficial while operating under vacuum. Differently shaped packing materials have different surface areas, which creates a void space between the packing that allows for absorption of gases and vapors. The combination of packing material, packing design, depth of packing, bed velocity, and the scrubbing liquid chemistry and quantity, are the factors that affect packing performance.

The purpose of a packed bed is typically to remove gaseous or vaporous pollutants from an air stream. To achieve this, the tower is filled with specially designed packing material, which are arranged or stacked to a specified depth (creating a stacked packed column). In the tower, the scrubbing liquids tend to wet the surface of the packing and when the polluted gas stream pass across this wetted surface, the pollutants get absorbed following the chemical reaction. 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.

The packed bed (or packed tower) scrubber is capable of only limited particulate matter control, and they easily choke with high solids loadings in the gas stream. The main contaminants that it can remove are:
