Achievable Emission Limits/Reductions: Scrubbers are capable of reduction efficiencies in the range of 50% to 98%. These are commonly used in conjunction with dehydrators, extraction plants, instruments, or compressors for protection from entrained liquids. DESIGN OF WET SCRUBBER The design of wet scrubbers depend on the industrial process conditions and the nature of the air pollutants involved in device. Packed-bed scrubbers, also called wet scrubbersor absorbing towers, are pieces of equipment installed in power plants to remove selected gases (and sometimes also particulates) from combustion fumes in order to meet emission standards. Wet Scrubbers. Wet Scrubbers Design of Wet Scrubber Detalis amp; Images Wet scrubbers are usually the most appropriate air pollution control device for collecting both, particulate and gas in a single system alone. The successful design and operation of wet scrubbers depends on knowing the size, composition, and derivation of the particles to be collected. The efficiency of a packed bed wet scrubber system can be defined as the effectiveness of the scrubbing process for fume removal. In dust scrubbers the dust particles are removed from a gas stream by a dispersed liquid. Gas flow rate.
