Packed Tower Scrubbing System Removes Chlorine (Cl2) Gas at Metal Refining Plant

A specialty metal refiner who recycles end of life batteries and other electronics needed to control a large chlorine gas release from its batch mixing process. The application required a unique scrubber design to ensure that sufficient neutralizing chemical was available to meet the required removal efficiency for a high load release.

Monroe Environmental designed a Packed Tower Scrubber System with a 1,000 gallon liquid reservoir to hold the required volume of scrubbing liquor. The system was designed to absorb the chlorine gas in a sodium hydroxide solution and convert it to byproducts of NaCl and NaOCl.

Scope of Supply:

  • Scrubbing Tower, polypropylene construction
  • Integral liquid reservoir with 1,000 gallon capacity
  • High efficiency packing media with supports
  • Mist Eliminator for final liquid droplet removal
  • Recirculation pump, piping, and valves
  • Instruments and valves for level control, pH, and conductivity monitoring
  • System control panel
  • All electrical items rated to Class 1, Div. 2 hazardous location
  • Coated steel skid

The system was rated for up to 3,000 ACFM.
