Cleanup Objectives: Recover hydrocarbons from ground water at RCRA site
Green Remediation Strategy: Uses a hybrid system employing solar and wind energy
- Began operating four wind-driven turbine compressors in 2002 to drive compressed air into hydraulic skimming pumps
- Began operating three 55-W photovoltaic panels in 2003 to power some recovery wells
- Added three 110-W photovoltaic panels and two wind-driven electric generators in 2006 to power a total of nine submersible total-fluid pumps and the fluid-gathering system
- Recycles recovered petroleum product by transfer to adjacent oil refinery for use as feed stock
Results:
- Recovered 228,000 gallons of free-product oil (approximately 20% of the estimated volume) by the end of 2006
- Integrated multiple renewable-energy technologies and resources over time to meet increasing portions of the recovery system's energy demand
- Avoids air emissions associated with consumption of grid electricity during petroleum recovery
- Provides for beneficial use of recovered material by local industry
- Avoids off-site transfer and disposal of petroleum product, along with associated air emission
Property End Use: Industrial operations
