Siemens Gas and Steam Turbines Power Dow in Stade, Germany

ERLANGEN, Germany (Oct. 17, 2014) – After successful completion of several months of testing and trial runs, three Siemens gas turbines were recently handed over to Dow Stade at Dow's new cogeneration power plant. The cogeneration plant is part of the energy concept for the Dow chemical site located in Stade, Germany, along the Elbe River and contributes to secure power supply for the entire site. The installed capacity of the plant is 163 megawatts (MW). The Siemens scope of supply comprised the planning, manufacture, factory testing, delivery, installation and commissioning of three SGT-800 industrial gas turbines as well as one SST-600 steam turbine. Handover of the steam turbine is scheduled for October 2014. Besides electricity, the new cogeneration unit will also supply process steam for the production processes in the chemicals complex. As part of the cogeneration site, each of the three gas turbines is connected to a downstream, supplementary fired heat recovery steam generator (HRSG), which feeds steam to the existing steam turbine as well as to the new steam turbine. The heat recovery steam generator is fueled with natural gas and hydrogen produced in the production process. “For Siemens, this confirms that we're offering the right products for a sustainable and economical energy supply,” said Wolfgang Konrad, CEO of the Distributed Generation Business Unit at Siemens. “Our gas turbines enable electricity to be generated extremely efficiently and with low emissions. We are happy with the cooperation with Dow Stade and also pleased to ensure that the power plant meets high standards for performance, availability and reliability.” Accident-free execution of the project had the highest priority both for Siemens and Dow. A zero-accident safety policy was strictly applied throughout the project. Due to the implementation of this common safety approach, no employee suffered an accident. The Siemens SGT-800 industrial gas turbine combines a long service life design with efficiency and low emissions. The turbine is qualified for gas turbine and combined cycle applications in simple cycle and cogeneration plants in the industry, in refineries, and in the oil and gas industry. More than 250 turbines of this series have been sold worldwide, and this fleet has accumulated more than 3 million equivalent operating hours (EOH). The Siemens SST-600, with its wide application range, has been installed in more than 77 countries all over the world. The reliable SST-600 has been delivered since 1974 and, in the meantime, has undergone a number of design enhancements that have led to improved efficiency and shorter startup times. The single casing turbine with front steam admission is designed for operation at speeds ranging from 3,000 to 18,000 rpm for generators or mechanical drives up to 150 MW. The turbine is used for both condensing and back-pressure applications. The Siemens Energy Sector is a supplier of a broad spectrum of products, services and solutions for power generation.
