H2SO4 Scrubber

Explanation

Sulfuric Acid Fume Scrubber systems are a diverse group of air pollution control devices that can be used to remove some particulates or gases from industrial exhaust streams. Traditionally, the term scrubber refers to pollution control devices that use liquid to wash unwanted pollutants from a gas stream.

Advantages

The advantage of the wet process separator is that it can also remove contaminated gases and has low manufacturing and maintenance costs. 0, NOx, SOx, SO2, SO3, HCl, HF Mercury, Metals, Chrome, CO, Dioxins, VOC, Cement O-HAPS. It can treat water soluble gas like: H2SO4, HCL, HF, CrO3, HCN, H2S and NH3, ect.

Mechanism

Sulfuric Wet Scrubber systems are a diverse group of air pollution control devices that can be used to remove some particulates or gases from industrial exhaust streams. Traditionally, the term scrubber refers to pollution control devices that use liquid to wash unwanted pollutants from a gas stream.

Sulfuric acid gas is highly toxic. Many Wet Sulfuric Acid Scrubbers utilize a multi-stage approach, first using a bed of packed media with recirculated liquid caustic (sodium hydroxide solution) which acts as a base to neutralize the acid, and finally uses a mist eliminator to remove water vapor.

Wet Sulfuric Acid Scrubbers can vary widely in terms of size and design.  Any number of factors must be considered, including:

  • The amount and concentration of sulfuric acid in the waste stream
  • The presence of other pollutants in the waste stream
  • The process conditions such as exhaust temperature and flow rate

Applications

  • Foundry Sections
  • Iron and steel industries
  • Food Manufacturing industries
  • Coal industries
