Project scope

  • Two-stage absorber and mist eliminator design
  • Chemical dosing, pH control, and circulation skids
  • Maintenance access, drainage, and corrosion-resistant equipment list

Observed challenges

  • Variable process load makes it difficult to keep the liquid-to-gas ratio stable.
  • Corrosive compounds such as HCl and HF make material selection critical.
  • Commissioning and maintenance information needs to be accessible quickly in the field.

Engineering approach

  • Flexible treatment architecture with venturi pre-scrubbing and packed-bed main absorption.
  • Operating notes that define the operating window for pumps, fans, and dosing equipment.
  • Weekly maintenance checklist and references to critical spare parts.

Application workflow

Step 1

Discovery data is collected for contaminant load, temperature, and liquid chemistry.

Step 2

Absorber layout, material selection, and balance-of-plant scope are defined.

Step 3

Commissioning, maintenance, and chemical-operation notes are shared with the customer team.

Frequently asked questions

What data is needed first for this type of project?

Gas flow, temperature, contaminant composition, liquid chemistry, and the target outlet condition should be clarified in the first design discussion.

Why should the maintenance plan be defined early on wet scrubber projects?

Nozzles, pumps, mist eliminators, and corrosion points directly affect field access; leaving them late increases downtime.
