California Chemical Scrubber Case Study: Eliminating Hydrochloric Acid (HCL) Emissions

This is an engineered chemical air scrubber and industrial wet scrubber system for hydrochloric acid fumes - not a janitorial floor scrubber and not HCL Tech. LibertyCES designed a custom HCL fume control solution to stop corrosion, eliminate safety risks, and meet strict air-quality requirements.

The facility required a polypropylene (PP) packed-bed wet scrubber with real-time monitoring, durable materials, and predictable capture efficiency for corrosive HCL vapors.

The Challenge: Controlling Corrosive HCL Fumes and Safety Risks

The facility faced severe corrosion issues and safety risks due to fugitive hydrochloric acid vapors, which are highly toxic to operators and destructive to standard metal piping.

  • Corrosion escalation: HCL fumes degraded ducting, valves, and nearby assets.
  • Operator safety risk: Acid vapor exposure created a hazardous work environment.
  • Compliance vulnerability: Emissions threatened EPA and local air-district thresholds.

The Solution: Custom Polypropylene (PP) Industrial Wet Scrubber System

LibertyCES engineered a chemical air scrubber designed specifically for HCL capture, using chemical-resistant polypropylene and real-time monitoring to stabilize performance.

Material: High-impact polypropylene for corrosive acid resistance.
Type: Packed-bed wet scrubber tuned for HCL fume control.
Performance: 99.9% HCL removal target under peak load.
Features: Real-time pH monitoring, double-containment piping, automated alarms.

How Our Industrial HCL Scrubber Works

Featured Snippet Bait (Exact Copy)

"Our industrial HCL scrubber works by drawing contaminated air into a vertical column packed with high-surface-area media. Inside, a neutralizing liquid is continuously sprayed over the packing, reacting with the hydrochloric acid fumes on contact. This chemical process converts toxic emissions into harmless salt water, releasing only clean, EPA-compliant air."

  1. Capture: Contaminated air is drawn into the system.
  2. Scrub: Acid fumes pass through packing media sprayed with neutralizing liquid.
  3. Neutralize: HCL reacts and converts into harmless salt water.
  4. Release: Clean, EPA-compliant air exits the stack.

Frequently Asked Questions About Chemical Scrubbers

Clear answers for engineers, operators, and compliance teams evaluating chemical air scrubber systems.

What chemicals do industrial scrubbers remove?
Our systems are engineered to remove corrosives like Hydrochloric Acid (HCL), Ammonia, and Chlorine.
Do HVAC air scrubbers work for industrial chemical fumes?
No. Industrial wet scrubbers are required for chemical fume control; standard HVAC scrubbers cannot handle corrosive acid vapors.
What are the EPA regulations for HCL emissions in California?
Requirements vary by process and local air district. LibertyCES designs to current EPA guidance and district-specific limits, then validates performance against your permit and operating profile.
