Is Gas Flotation Of Petroleum Produced Water greatly affected by temperature

Temperature Effects on Gas Flotation Efficiency

• Water Viscosity Impact
  Low temperatures (<10°C) increase viscosity, hindering bubble movement.
  High temperatures (>40°C) may degrade flocculants.
• Air Solubility Relationship
  Air solubility drops from ~33 mg/L at 20°C to ~24 mg/L at 40°C (Henry's Law).
• Oil Droplet Behavior
  Cold makes oil viscous/stable, while 25-35°C optimizes droplet aggregation.
  Above 40°C risks oil volatilization.
• Optimal Operating Range
  Field data shows 20-35°C balances all factors, with 15-20% higher efficiency at 25°C vs 10°C.

Mitigation strategies include temperature control systems, preheating/cooling, and temperature-resistant chemicals. Continuous monitoring is essential for consistent performance.
