Honorable Mentions: GTX – Cogeneration Project, owned by Dubai Aluminum Co. Limited, Dubai, United Arab Emirates

Dubai Aluminum (DUBAL) is one of the largest single-site aluminum smelters in the world. The site includes a 2,350 MW power station (at 30˚C) comprised of 22 gas turbines and seven steam turbines; a water desalination plant and a large carbon plant. The power station is designed to provide both electricity to the smelter reduction process and saturated steam to the water desalination plant.

The new power plant would use one large state-of-the-art gas turbine and a heat recovery steam generator, and then supply the steam heat energy to three existing Frame 9E steam turbines and the water desalination plant. The cogeneration cycle is designed to work in three modes: additional steam heat energy to operate the existing Steam Turbines on peak load; additional steam heat energy to replace one existing HRSG; or steam heat energy to the water desalination plant.
