Sulfuric Acid Scrubbers: What is Sulfuric Acid and Why Does it Require Emission Control?

Sulfuric acid is reactive and an explosive hazard within manufacturing processes. It acts as a strong oxidizer that can enhance the combustion of other substances. Classified as a hazardous substance, facilities that emit sulfur-based substances such as sulfuric acid or sulfur dioxide must remove these toxic byproducts from their emissions. Pollution Systems manufactures highly efficient Sulfuric Acid Scrubbers built around your precise requirements.


Sulfuric Acid Scrubber Design

Wet Scrubbers remove pollutants by injecting liquid into the gas stream; in Dust Scrubbers, the particulate is caught by water droplets, preventing it from escaping through the exhaust pipe. Chemical Scrubbers function differently - the liquid introduced into the gaseous waste stream causes chemical reactions that convert the pollutant(s) into a different chemical compound.   

In the case of Sulfuric Acid Scrubbers, efficiency is critical due to the corrosive nature of sulfuric acid gas. 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 using a mist eliminator to remove water vapor.

Wet Sulfuric Acid Scrubbers can vary widely in terms of size and design; Several factors require consideration, 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


A range of designs and approaches are available for Wet Scrubbers, but all generally incorporate:
