Your Complete Fume Scrubbing System

Modern steel mill pickle lines utilize Hydrochloric Acid to clean the surface of the steel sheet. Acid mist and fume is generated during this process. 

CECO Busch and our sister firm HEE-Duall provide complete fume scrubbing systems to capture and neutralize this acid fume.  Our systems begin at flanged connections to the pickle line tank covers.  Fiberglass duct connects the tank covers to the scrubber and fan which exhausts to the outdoors by means of an exhaust stack.

The Pickle Line Scrubber is a counter current packed bed scrubber consisting of packed tower complete with flanged horizontal radial gas inlet, glass-filled polypropylene random packing. This allows for excellent mass transfer resulting in high efficiency capture of HCl fume at a minimum pressure drop.

  • The scrubber housing incorporates a vertical or horizontal outlet flange to facilitate installation in limited space.
  • The packing is irrigated by internal piping and liquid distribution system.
  • HCl is scrubbed by using a re-circulation wash water solution from integral self-contained re-circulation tank at the bottom of the scrubber.
  • Blow-down from the re-circulation system serves as make-up water to the pickle line.

We deliver top-performing mist eliminators with optional internal spray piping and spray nozzle to intermittently wash the underside of the mist eliminator, triggered by either high-pressure differential or on a timed sequence.

The cleaned gas from the Scrubber is sent to a System ID fan via an interconnecting duct and then to stack. Click here to download our Steel Brochure.  

Note: Acid storage tank vents may also be connected to the system.

Materials of Construction:

  • Scrubber Vessel – FRP or PVC
  • Random Packing – Glass filled Polypropylene
  • Internal Piping and Liquid distribution system – CPVC
