GE’s 5 ppm Dry Low NOx System to Debut in Dow Chemical Plant BARCELONA, SPAIN (May 25, 2004) — GE Energy’s latest-generation Dry Low NOx (DLN) system, the DLN 1+, for GE E-class gas turbines, is able to reduce NOx emissions to five parts per million (ppm) or less. It will be retrofitted to two gas turbines located at The Dow Chemical Company’s (Dow) chemical complex in Freeport, Texas, GE reported at Power-Gen Europe 2004. By enabling significantly reduced NOx emissions within the combustion system itself, the GE DLN 1+ solution eliminates the need for expensive, post-combustion cleanup methods, such as selective catalytic reduction (SCR) systems, to be installed downstream of the turbine exhaust system. By eliminating the need for an SCR system, plant owners are relieved of the cost and downtime of a major installation, along with avoiding the SCR’s plant performance impact, associated maintenance costs and ammonia emissions. In addition, the latest generation of the GE DLN 1+ system’s components are designed to provide plant owners with higher levels of availability by offering extended operating intervals between maintenance outages. “This new, advanced DLN system is a significant achievement not only from an environmental standpoint, but also from a financial standpoint,” said Ricardo Artigas, president of energy services for GE Energy. “The technology builds on the more than 10 million hours of successful operation that GE DLN systems have accumulated in gas turbines worldwide and helps our customers meet today’s most stringent environmental requirements.” In addition to reduced NOx levels, GE’s DLN systems are designed to achieve low system dynamics, long parts lives and inspection intervals, and extended operating ranges. These DLN systems have been released for production following the completion of extensive laboratory and field testing by GE Energy. This testing was aimed at verifying emissions, performance and durability of the components, and has been highly successful over a wide range of operating conditions. The gas turbines at the Dow Freeport facility are 75-megawatt, Frame 7E machines being used to produce power and steam for the site chemical complex. The turbines are using natural gas as the primary fuel, although the DLN equipment will allow the flexibility to burn hydrogen-bearing fuel in the future. Dow is undertaking the retrofit project to assist in meeting new emissions regulations in the region. The GE DLN equipment will be delivered in early 2005 for installation during Dow’s subsequent planned outages.
