Chlorine Scrubbers

A Chlorine Scrubber is an air pollution control device specifically designed to remove chlorine gas (Cl2) from industrial exhaust streams. Chlorine is a highly toxic, corrosive gas commonly used in water treatment, chemical manufacturing, and pharmaceutical industries. The scrubber works by passing contaminated air through a packed bed or spray tower where it contacts a neutralizing scrubbing solution, typically containing sodium hydroxide. This chemical reaction converts chlorine gas into a harmless salt solution, effectively reducing hazardous emissions.

Chlorine Scrubber

Chlorine scrubbers are engineered to maximize contact between contaminated gas and scrubbing liquid, significantly improving absorption efficiency. Many systems include mist eliminators or demisters to capture residual droplets before the cleaned air is discharged. These scrubbers are crucial for industries that handle or produce chlorine, offering safe and efficient removal of this gas from exhaust streams. By neutralizing chlorine into safer by products, these systems protect worker health, reduce environmental.

Chlorine Scrubber FAQs

About Chlorine Gas Removal Systems

FRP (Fiber-Reinforced Plastic) is inherently corrosion-resistant, ensuring the scrubber’s structural integrity even when continuously exposed to aggressive chlorine gas and acidic liquor.
Gas passes upward through a packed bed while an alkaline solution trickles downward, dissolving and neutralizing chlorine. This counter-current design maximizes gas–liquid contact, delivering > 99 % efficiency.
By adjusting the scrubbing liquor pH and, if needed, adding a secondary stage, the unit can simultaneously remove HCl, SO2 and other acid fumes along with chlorine.
Every chlorine scrubber is designed to meet or exceed Central Pollution Control Board (CPCB) and Tamil Nadu PCB emission standards. We provide performance guarantees backed by third-party testing.
Regular tasks include pump inspection, nozzle cleaning, and monitoring pH/ORP of the recirculation tank. We offer annual maintenance contracts to handle these checks and ensure uninterrupted operation.
