LibertyCES has documented Chemical Scrubber in Acids service, including Hydrochloric Acid. Wetted materials to confirm: Polypropylene. Documented models include LibertyCES custom packed-bed PP scrubber. Compatibility depends on exact concentration, temperature and duty cycle, so confirm with a free spec review.
Notes from the vendor documentation
HCl fume scrubber case study: 'Polypropylene is commonly selected for hydrochloric acid fume control because it resists corrosion better than many metals in acid vapor service.'

The plant's core problem before this scrubber was corrosion escalation — HCl fumes degrading ducting, valves, and metal assets — which is the exact failure mode PP construction with chemical-resistant PP ducting is specified to eliminate.
This California plant was losing ducting, valves, and metal assets to HCl fume corrosion before the switch to a custom high-impact PP packed-bed scrubber with pH-monitored automated alarms. Most suppliers sell what you're asked for; Liberty CES, under James Riggins's 30+ years of zero-failure spec experience, determined polypropylene construction was what the application actually required.
Every material and product claim on this page traces to real, vendor-published documentation on file with LibertyCES. Chemical compatibility depends on exact concentration, temperature, and duty cycle — confirm current specifications with the manufacturer and request a spec review before final specification.
