Variable Volume Vapor Recovery Unit (V3RU)

MV's V3RU captures oil tank vapors caused by solar heating and condensate induced flashing in production oil tanks.

Features:

• Low Capital and Maintenance Costs
• Field Proven Design
• Skid mounted design facilitates installation
• Meets new emissions regulations

The V3RU operates on the unique approach of using a "Constant Pressure, Variable Volume" Accumulator that prevents oxygen intake while allowing a more steady-state compression of the tank vapors into the sales line.

Condensate is trapped in the Accumulator for re-use or disposal. The vapor compressor (patent pending) is driven by well head pressure drive gas, eliminating a power source for the compressor.*

*Natural Gas and Electric Generator powered compressors are available.

The V3RU Accumulator is skid mounted, internally controlled and virtually maintenance free. The flexible membrane is installed within a vertical skid-equipped culvert for safety and a minimum foot print.

Advantages of the V3RU:

1. MEETS REG 7 AND OTHER EMISSION CONTROL REQUIREMENTS.
2. THE V3RU HAS ECONOMIC PAYOUT FROM THE SALE OF RECOVERED GAS.
3. UNIQUE: PATENT PENDING.
4. BOOSTER COMPRESSOR REQUIRES NO OUTSIDE POWER SOURCES AND NO OIL CHANGES.
5. CAPTURE OR RESALE OF PRODUCTION TANK VAPORS.
6. SIMPLE SKID MOUNTED DESIGN.
7. PREVENTS AIR/OXYGEN INTRODUCTION INTO PRODUCTION TANKS WHEN OPENING THIEF HATCH AND GAUGING OR DRAINING PRODUCTION TANK.
8. CAN BE SIZED TO ACCOMMODATE ANY TANK BATTERY OR INDIVIDUAL WELL PRODUCTION TANK.
9. LOW CAPITAL COSTS.
10. CAPTURES ANY LIQUID (WATER OR CONDENSATE) FOR FUTURE DISPOSAL OR RESALE (as appropriate) AND PROTECTS THE COMPRESSOR.
11. POSSIBLE GREEHOUSE CREDITS FOR PRODUCER.
12. SIMPLE. VAPOR RECOVERY UNIT OPERATION IS BASED ON FAMILIAR OILFIELD OPERATIONS.
13. MORE CONSTANT FEED RATE INCREASES FLARE EFFICIENCY AND SAFETY.

Field applications have proven the V3RU System to be safe, reliable, and low maintenance. MV's V3RU is compliant with the regulatory emissions requirements of REG. 7 in Colorado, oil/gas documents for the Jonah/Pinedale fields in Wyoming, and emission controls regulations in other areas such as Texas.

The V3RU purchase and installment costs are generally recovered within 7-36 months from the sale of the recovered gas. In addition, the purchaser may benefit from greenhouse gas capture and reuse as a seller of greenhouse gas credits. Units are available in fixed or mobile systems.

Applications:

• Oil Fields (to offset propane costs for Ajax type engines)
• Production Tank Batteries
• Compressor Stations
