Description
Technical Data
Benefits
Design Concept
Package

The three shaft industrial gas turbine SGT-500 is a light weight, high efficiency, heavy duty machine. It operates reliably in the 15-20 MW power range and can handle a variety of fuels. For both, industrial power generation and mechanical drive, the SGT-500 is a proven unit. The SGT-500 is available as a factory assembled package and provides an excellent power-to-weight ratio. Moreover, the SGT-500 has successfully undergone a comprehensive test program on heavy fuel oil for marine applications.

Crude Oil Capability

Increases energy efficiency of oilfield operations
Reduces global CO₂footprint of Heavy Oil production
Bi-Fueling (Mixed Fuel Operation) reduces the need to flare associated gas
Core engine exchange concept (in less than 48 hours)
Longer component life due to lower firing temperatures

The modular, compact design of the SGT-500 facilitates easy on-site service – complete modules can be swiftly exchanged. The SGT-500 contains a twin-shaft gas generator: The low pressure axis contains a 10 stage low pressure compressor and a 2 stage low pressure turbine. The high pressure axis contains an 8 stage high pressure compressor and a 1 stage high pressure turbine. The three-stage power turbine speed is 3,600 rpm for power generation and 3,450 rpm for mechanical drive. In order to increase efficiency, a blade tip clearance adjuster is connected between the power turbine stator and rotor. The gas turbine is available with a conventional or Dry Low Emissions (DLE) combustion system. Both systems provide dual fuel capability, the DLE system also providing extremely low NO_X levels.

Crude Oil Capability

Accepts liquid fuels with viscosities up to 20cSt
Fuels pre-heated to as high as 150°C
Possible usage of fuels with viscosities of 750cSt at 50° or higher due to pressurized fuel system

The SGT-500 is available as a factory assembled package. It is easily transported, installed and maintained at site. The package incorporates the gas turbine, gearbox, generator (for PG applications) and all systems mounted on a single underbase. Turbine controls, generator control panel, motor control center for package motors and variable speed drive for starter motor are normally also package-mounted.
