Dow selects System 800xA for Power Generation
2010-04-16 - U.S. chemical giant, Dow Chemical, has selected ABB’s System 800xA for Power Generation for phase 1 of a new high efficiency cogeneration power plant at the Stade chemical production complex in northern Germany. Dow has named System 800xA the ‘most effective technology’ on the market in distributed control systems.
The new gas and hydrogen-fired boiler plant is part of an integrated energy concept developed by Dow to secure the long-term supply of power and steam for the complex at economical cost and with minimal environmental impact.
Stade is a key site in Dow’s global network of production centers, producing some two million tons of chemicals a year at 18 production plants on a 550 hectare site.
ABB is providing a distributed control system for the new power plant based on its System 800xA for Power Generation platform. The solution includes AC 800M controllers, AC 800M high integrity controllers for integrated safety functions, and S800 I/O technology. ABB is also responsible for engineering, supply, and commissioning of the control system.
Preferred automation platform
ABB will execute the project under its existing global framework agreement with Dow Chemical for control system solutions, service and support.
Dow has selected System 800xA as the most effective technology on the market for achieving production excellence in distributed control systems, and uses System 800xA as its preferred process control platform at production sites all over the world.
System 800xA will enable the new power plant to operate at high levels of efficiency and availability, and will provide it with integrative and operational capabilities that are unique to the System 800xA for Power Generation platform.
Among other things, the solution enables Dow to integrate the power plant electrical into the process control systems via the IEC 61850 standard for interoperable intelligent electronic devices. It also integrates the safety and protection systems, providing Dow with the option of combining the control and safety functions within the same controller or keeping them separate within the same system.
