  1. Refinery Water Balance

  2. Thumbnail Sketch of Return On Investment for Sour Water Capture • Where Applicable: Any Distillation Column Overhead Water Accumulator. • Estimated Equipment Capital Investment: ~ $800 K. • Return on Investment via Realized Reductions in O&M costs: ~ 18 Months. • Ongoing O&M Cost: < $0.10 per 1000 gallons.

  3. Benefits of Capturing Sour Water For High Quality Process Supply Water • Removes considerable contaminant loads to wastewater plant, thus reducing central wastewater plant O&M costs. • Provides steam condensate quality boiler feedwater. • Resulting supply water does not need pretreatment for boiler feedwater, such as Ion Exchange or Reverse Osmosis, thus reducing pretreatment costs. • Recovers considerable lost heat in wastewater and reuses to preheat boiler feedwater, thus saving considerable money in lost BTUs and fuel costs. • Greatly reduces Boiler Water chemical and blowdown costs by increasing permissable Cycles of Concentration.

  4. Integrating The Solutions

  5. Get The Basic Costs

  6. GEW&PT Service and Chemical CostSummary

  7. Impact of feedwater quality on boiler operational efficiency 50 cycles versus 10 cycles saves $300,000/yr 50 cycles versus 10 cycles saves $120,000/yr 50 cycles versus 10 cycles saves $10,000/yr

  8. CVR: Condensate RecoveryPotential Saving: $ 1,263,132

  9. Project: Cost of Steam LeaksCan we find 10 leaks? $2MM Savings
