Siemens installs demineralization line for OMV refinery in Burghausen, Germany

The Siemens Industrial Solutions and Services Group (I&S) is installing a new demineralization line in the Burghausen refinery for OMV Deutschland GmbH and connecting it to existing systems. This aim is to cover the boiler feedwater needs of the expanded ethylene plant. Commissioning of the demineralization line is scheduled for summer 2007.

OMV Deutschland GmbH is the leading mineral-oil company in south Germany. With a 45 % holding in Bayernoil Raffineriegesellschaft, OMV has an annual crude-oil refining capacity of 8.8 million metric tons. The refinery in Burghausen mainly produces high-quality middle distillates, petrochemical raw materials and petroleum coke for the aluminum industry.

With the commissioning of the new cracking furnaces of the expanded ethylene, the need for boiler feedwater has increased. This necessitates a third treatment line (Row 6) for fully demineralized water from well water and a second mixed bed filter. The process engineering and technical aspects of the new line will be such that it will reliably produce salt-free potable water that can be used for high-pressure steam boilers.

Siemens is to build the complete demineralization line and integrate it into the existing systems. The new line includes a cation and anion exchanger – each of which uses a fluidized bed procedure and has a capacity of 180 m³/h – plus CO2 removal by means of a trickler, including blower, and also pumping with trickle pumps, one of which will be in operating mode and the other in stand-by mode. The mixed bed exchanger with a capacity of 360 m³/h is also part of the scope of supply. In addition, the media needed for operating the demineralization line such as compressed air, hydrochloric acid and caustic soda will be integrated into the existing plant and into the supply and removal systems.

Siemens is also responsible for planning, designing, project management, manufacturing and commissioning as well as trial operation and preparation of the documentation.
