Scrubber Modules for Acid Gas Treatment-Image

How the Anguil Scrubber Module Works

The acid containing stream is directed to the scrubber module where a recirculation pump injects large volumes of water into a quench section, inducing vapor flow through the scrubber. Water then quenches the hot vapor and absorbs a portion of the acid.  The gases exit the eductor and enter a countercurrent absorption column.  Recirculation solution is fed to the top of the absorption column through a nozzle.   The remaining acid vapors are absorbed into the solution while the gases pass through a mist eliminator before exiting the column.  Sodium hydroxide, or another caustic, is added to control the pH in the sump to the neutral range.


  • High temperature systems available for processes up to 1800oF (982 oC)
  • pH control system automatically monitors the solution to a neutral solution, optimizing scrubbing efficiency
  • Conductivity controller regulates water discharge from the scrubber and ensures there is no salt buildup
  • Automatic liquid level controls monitor the liquid in the sump
  • Automatic fresh water make-up prevents water depletion
  • High temperature safety shutdown
  • Programmable Logic Controller (PLC) based controls with digital data recorder and remote telemetry.  Truly integrated control system with the oxidizer.
  • Variable Frequency Drive (VFD) allows for high volumetric turn-down during idle or low process conditions
  • Completely shop assembled, pre-wired and tested prior to shipment

Available Options:

  • Complete "turnkey" packages
  • Forced or induced draft arrangements
  • Diverse material of construction options depending on the acid and inlet temperature to the quench
  • Skid or remote mounted panels and enclosure rooms available for system controls
  • Custom designed options to meet space restrictions
  • Winterization packages
  • SO3 removal systems
