HCL Fume Scrubber: Capturing Corrosive Hydrochloric Acid Vapors
LibertyCES engineered a custom HCL vapor control system to reduce corrosion risk, improve operator safety, and support local air-district compliance requirements — a polypropylene packed-bed wet scrubber with corrosion-resistant materials, real-time monitoring, and durable ducting.
Controlling Corrosive HCL Fumes and Safety Risks
The facility needed to control hydrochloric acid fumes that were creating corrosion, operator exposure risk, and air-quality compliance concerns. LibertyCES specified a chemical-resistant polypropylene packed-bed wet scrubber to capture and neutralize HCL vapors before exhaust air left the system.
Corrosion escalation: HCL fumes degraded ducting, valves, nearby metal assets, and exposed equipment.
Operator safety risk: Acid vapor exposure created a hazardous work environment around the process area.
Compliance vulnerability: Fugitive fumes created risk against permit limits, local air-district requirements, and workplace safety goals.
Material Selection for HCL Fume Service
Polypropylene is commonly selected for hydrochloric acid fume service because of its chemical resistance to corrosive acid vapor — a durable, cost-effective material choice for packed-bed wet scrubber construction.

How the Scrubber Captures and Neutralizes HCL Fumes
A packed-bed wet scrubber works by forcing contaminated air through a wetted media bed so acid gas contacts a neutralizing liquid before exhaust air leaves the system.
- Capture: Contaminated air is drawn from the process area into the scrubber system.
- Contact: Acid fumes pass through packed media wetted with neutralizing liquid.
- Neutralize: HCL vapor is absorbed into the liquid stream and neutralized under controlled pH conditions.
- Monitor: pH and system conditions are tracked to keep performance within the required operating range.
- Discharge: Treated exhaust air exits the system after the acid gas control step.

HCL Fume Scrubber FAQ
What is a chemical air scrubber used for?
A chemical air scrubber captures and neutralizes corrosive or hazardous fumes — like hydrochloric acid vapor — before exhaust air leaves a process area, protecting equipment from corrosion and reducing operator exposure risk.
Why use polypropylene for an HCL fume scrubber?
Polypropylene is commonly selected for hydrochloric acid fume service because of its chemical resistance to corrosive acid vapor, making it a durable material choice for packed-bed wet scrubber construction.
Is this the same as a floor-cleaning or HVAC scrubber?
No — this page covers industrial chemical air scrubbers for hydrochloric acid fume control specifically, not floor cleaning scrubbers, HVAC air purifiers, or unrelated technology of a similar name.
