Siemens has received a new order for the installation and commissioning of Wet Compression Systems for its eight SGT5-4000F gas turbines installed in the Nubaria, Talkha and Kureimat Power Stations in Egypt. By using wet compression, each turbine can generate an additional 25 megawatts (MW), and at the same time, reduce the NOx emissions by more than 30 percent per turbine. The customer is the Ministry of Electricty in Egypt represented by Middle Delta Electricity Production Company & Upper Egypt Electricity Production Company.
The Ministry of Electricity of Egypt ordered Wet Compression Systems for all eight of the gas turbine units they operate in Egypt. Siemens will install the first two systems during scheduled outages between January and April 2011 in the combined cycle power plant Nubaria. Thus, the Ministry will be able to produce an additional 50 MW of capacity before the summer peak of 2011.
“This project is significant for both the Ministry of Electricity of Egypt and Siemens,” said Randy Zwirn, CEO of Siemens Energy Service. “It secures valuable additional power output during the summer peak and, at the same time, demonstrates Siemens’ ability to provide innovative solutions for our customers.”
Wet compression is a reliable and proven method of injecting water into the gas turbine inlet and is perfectly suited for peak load applications. Wet compression is designed to increase the power output of the gas turbine by reducing compressor inlet temperatures, intercooling the compressor and increasing mass flow throughout the turbine.
The Siemens Wet Compression system has been successfully installed and operating in DEWA’s Jebel Ali G since 2005 and in K Station since early 2010.
Wet compression systems are part of the Siemens environmental portfolio with which the company earned revenues of around EUR28 billion in fiscal 2010. This makes Siemens the world's largest provider of environmentally compatible technology. Using the appropriate Siemens products and solutions, customers have reduced their carbon emission (CO2) by 270 million tons over the same period; an amount equal to total annual CO2 emissions of Hong Kong, London, New York, Tokyo, Delhi and Singapore.
