Chemical Gas Scrubbers

What are Chemical Gas Scrubbers?

Chemical Scrubbers – often called Gas Scrubbers – are specifically designed to remove one or more gas pollutants depending on the client’s needs. Often, these pollutants are chemicals such as ammonia, chlorine, or sulfur compounds.

These high-efficiency Chemical Gas Scrubbers work by dissolving or absorbing the pollutant into the scrubbing liquid. The scrubbing liquid used will depend on the properties of the targeted pollutants. Pollution Systems manufactures scrubbers that incorporate high-quality design and construction for long-term operation and minimal equipment maintenance.

How Does a Chemical Gas Scrubber Work?

Ensuring the appropriate contact time between the gas and the scrubbing liquid occurs allows for effective gas removal efficiency using a chemical scrubber. Chemical Gas Scrubbers include random packing to facilitate gas-to-liquid contact. Exhaust gas enters the scrubber, contacting the scrubbing fluid and becoming captured. It then collects for discharge or is treated for reuse.


Pollution Systems constructs our Chemical Gas Scrubbers out of FRP, which is more durable and long lasting than polypropylene. Also, our scrubber systems reduce chemical and electricity consumption thanks to their fully automated design.

Common Industrial Applications

Types of Chemical Gas Scrubbers

  • Ammonia Scrubber – removes the targeted pollutant of ammonia by using caustic as a neutralizing agent.
  • Sulfuric Acid Scrubber  – uses caustic as a neutralizing agent to scrub sulfuric acid from the process.
  • Chlorine Scrubber – Scrub chlorine using an alkaline solution as a neutralizing agent.

Frequently Asked Questions

Scrubbers can remove many gaseous chemicals. Common chemicals include hydrogen sulfide, suflur dioxide, ammonia, chlorine, ethylene oxide, and phosphoric acid.

Our packed-bed scrubbers use engineered random packing of various materials including polypropylene, polyethylene, and PVDF for high efficiency and lower pressure drop.

Yes, chemical scrubbers are often used to treat odors. The reagent will depend on the odors being treated. For example, H2S is treated with sodium hydroxide (caustic) and sodium hypochlorite (dilute bleach).
