public class ProducedWaterTreatmentTrain extends ProcessEquipmentBaseClass
Produced water treatment train for offshore oil and gas facilities.

Models a typical produced water treatment process including:

  • Hydrocyclone - Primary oil removal (bulk separation)
  • Flotation unit - Secondary treatment for fine droplets
  • Skim tank - Polishing for final discharge spec

Norwegian Continental Shelf Discharge Limits

  • Oil-in-water: 30 mg/L monthly weighted average
  • Dispersed oil: Monitored daily
  • Zero harmful discharge target

Typical Equipment Performance

Equipment Removal Efficiency
Equipment Droplet Size Efficiency
Hydrocyclone >20 μm 90-98%
IGF/DGF >5 μm 80-95%
Skim Tank >50 μm 60-80%
