Instant 1 MW Power Boost for Offshore Gas Re-Injection Well

Fog Cooling For Gas Turbines & Heat Exchangers

Reliable Performance in Extreme Conditions

An offshore gas re-injection well in the Persian Gulf needed to maintain high levels of productivity despite challenging environmental conditions, where temperatures often soared to 93°F (34°C). The high ambient temperatures were reducing the power output of the gas turbine, leading to decreased efficiency in gas compression. Mee Industries provided an advanced inlet air cooling system specifically designed to operate under these harsh conditions. The system was installed on a Rolls Royce RB211G gas turbine, effectively cooling the inlet air by up to 25°F (14°C) and delivering a power boost of 1 MW. This cooling system allowed the well to maintain high efficiency, even during the hottest months.

MeeFog’s Inlet Air Cooling System Implementation:

System Design:
- Designed a seven-stage fogging system capable of reducing inlet air temperatures by 25°F (14°C).
- The system was engineered to meet the specific requirements of the offshore platform, operating at a pressure of 2,000 psi with fog droplet sizes of 8 microns.
Installation:
- Supplied and installed the fog pump skid, nozzle manifolds, and other components necessary for the system.
- Supervised the installation and commissioning to ensure that the system was fully operational and optimized for the environment.
Performance Testing:
- After 25,000 hours of operation, the system was tested during the extreme climate conditions from May through July. The results showed a significant improvement, with an additional six to seven MMSCFD (million standard cubic feet per day) of gas being pumped.

Measurable Outcomes:

Power Boost: The MeeFog™ system delivered a power boost of 1 MW, which was crucial for maintaining productivity during peak temperature periods.
Increased Gas Compression: The system enabled the pumping of an additional six to seven MMSCFD of gas, significantly enhancing the well’s output.
Efficiency: The cooling system operated efficiently with a maximum water flow of 8.8 gpm and a power requirement of just 15 HP, making it an energy-efficient solution.
