ABB has won a contract from ThyssenKrupp Stahl to furnish electrification and process control for its new coking plant in Schwelgern, Germany. The contract, valued at around US$32m, will ensure all automation levels of the new plant are continuously connected within a network, ABB said. The complete data flow reaches from the plant control level to the individual measuring sensor.
With the coking plant divided into production units; it will require sophisticated process control.
Basic automation will use the ControlITModule CMC 70. The system field devices are connected via the Profibus DP/PA directly to the process control system, and can be configured and parameterised with EngineerIT. With 25,000 I/Os, it will be the world's largest Profibus system for industrial plants.
In addition to the measurement and control devices, the contract also includes the delivery of necessary analysis technology and the medium and low voltage switchgear systems, including transformers.
As the general contractor, ABB is also responsible for providing numerous other facilities, such as plant lighting and communication.
The finished plant will be handed over in 2003, and will feature only two batteries of 70 coke ovens each, compared to six batteries and a total of 354 coke ovens in the old August Thyssen plant.
It is predicted that every day, 10,600 tonnes of coal will be converted into coke, with the annual coke production will amount to approximately 2.5 million tonnes.
