Case Study — Chemical Air Scrubber
California HCL Fume Scrubber Case Study: Capturing Corrosive Hydrochloric Acid Vapors
This page covers industrial chemical air scrubbers for hydrochloric acid fume control — not floor cleaning scrubbers, HVAC air purifiers, or HCLTech. LibertyCES engineered a custom HCL vapor control system to reduce corrosion risk, improve operator safety, and support local air-district compliance requirements.
The facility required a polypropylene packed-bed wet scrubber with corrosion-resistant materials, real-time monitoring, durable ducting, and predictable capture performance for corrosive HCL vapor service.

What Problem Did This Solve?
The facility needed to control hydrochloric acid fumes before they damaged equipment or exposed operators.
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.
The Challenge
Controlling corrosive HCL fumes and safety risks.
The facility faced corrosion and safety concerns due to fugitive hydrochloric acid vapors. HCL fumes are highly corrosive to nearby assets and create exposure risk when they are not captured and treated correctly.
- 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.
Why Polypropylene?
Why use a polypropylene packed-bed wet scrubber for HCL fumes?
Polypropylene is commonly selected for hydrochloric acid fume control because it resists corrosion better than many metals in acid vapor service. A packed-bed wet scrubber increases gas-liquid contact area, allowing the neutralizing solution to contact and absorb more acid gas before discharge.
The Solution
Custom polypropylene industrial wet scrubber system.
LibertyCES engineered a chemical air scrubber designed specifically for HCL fume capture, using chemical-resistant polypropylene, packed-bed gas-liquid contact, and monitoring logic to support stable operation.
Plain-English Explanation
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.
How the Industrial HCL Scrubber Works
The system draws HCL-contaminated air into a vertical scrubber body packed with high-surface-area media. A neutralizing liquid is distributed over the packing, increasing contact between the acid vapor and the liquid stream. The neutralization process converts acidic vapor into a managed salt-containing liquid stream that can be monitored, treated, and handled according to the facility’s wastewater and environmental requirements.
- 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.
