Siemens Energy ships 100th SGT-300 industrial gas turbine
Erlangen, Germany, 2011-Oct-05
In late September 2011, the 100th SGT-300 industrial gas turbine left the Siemens manufacturing plant in Lincoln, UK, en route to Iraq. The turbine is one of a total of three ordered in early 2011 by Petrochina Company Limited for the end user China National Petroleum Corporation (CNPC). All three turbines will generate power and process heat in the oil and gas industry.
The SGT-300 has proven itself as a very flexible gas turbine in a variety of applications. Since the first turbine was delivered in 1996, the SGT-300 has been employed for power generation and in cogeneration duty all over the world in a wide range of industrial applications, from pulp and paper to food and beverages, textiles and ceramics, chemicals and petrochemicals. The most important market is the oil and gas industry. The oil and gas installations have been both onshore and offshore, on drilling platforms or FPSO (Floating, Production, Storage and Offloading) vessels. Thanks to the high-grade construction materials used, the SGT-300 is highly resilient to hydrogen sulfide. It can thus be operated on sour gas, minimizing gas processing costs.
The power generation model is a single-shaft 7.9-megawatt (MW) gas turbine featuring a Dry Low Emissions (DLE) system, which ensures low nitrogen oxide emissions. An 8.2-MW (approximately 11,000 hp) twin-shaft version of the SGT-300 is available for mechanical drive applications. This version is based on the field-tested designs of Siemens industrial gas turbines, sharing the combustion and compression systems of its single-shaft sibling and deriving other turbine technology from the remainder of the industrial turbine family. The twin-shaft turbine is designed for compressor and pump drives in the oil and gas market. The complete turbine plant with auxiliaries and ancillary equipment can be supplied both as an onshore and offshore package. Thanks to the compact design the turbine's weight and its space requirements are relatively small.
"The SGT-300 is one of our most versatile industrial turbines," said Markus Tacke, CEO of the Industrial Power Business Unit of Siemens Energy. "With a firing temperature of 1152 degrees Celsius and ten compressor stages, the engine is designed above all for maximized reliability."?
