Success Story: Reliable and Cost Efficient Monitoring of Process Off-Gases

The unique "Plug & Play" design and modularity of the system offer flexible solutions that can be attuned exactly to the individual measuring task.
The oxygen gas measurement system from METTLER TOLEDO is an effective tool in explosion prevention procedures as employed by WACKER at its production site in Burghausen, Germany. This inline measurement substantially reduces maintenance costs and offers real-time monitoring of process off-gases.
Wacker Chemie AG, Burghausen, Germany
Burghausen lies in the district of Upper Bavaria, 110 km east of Munich, close to the border with Austria. The town is characterized by the longest reach of castle compounds in Europe, its medieval quarter, and above all by the WACKER chemical plant site. The works established there in 1914 are today the most important production facilities of the WACKER Group as a whole, and the largest chemical complex in Bavaria. At this over two square kilometer site, some one thousand different products are produced by roughly 10,000 employees divided among 150 different production plants. The spectrum of products ranges from polysilicon and hyperpure silicon wafers over silicones, silanes and silicic acids through to dispersions, redispersible powders, solid resins, paint resins, fine chemicals and biotechnological products.

Business Division SILICONES
WACKER SILICONES ranks among the largest silane and silicon producers in the world. Highly differentiated properties make silicone ideal for a large number of applications. In the sector "Functional Silicones and Oils", under the management of Corinna Müller, about 75 employees are engaged chiefly in the manufacture of preliminary products for e.g. the automobile industry, building materials protection sector, and cosmetics industry.

Comprehensive safety design
Safety is a top priority at all WACKER sites. Thanks to a comprehensive safety program, the accident rate lies well below the average for this industry. Part of the safety program is an effective inertisation strategy for (process) offgases, i.e. ensuring an oxygen-free waste-gas discharge system. To ensure that the waste-gas stream is totally oxygen-free in terms of active explosion prevention, the "Functional Silicones and Oils" plant employs oxygen measurement technology from METTLER TOLEDO. The safety program stipulates that oxygen concentration in the wastegas stream must be below 5 vol. % O2. If this limit is ever exceeded, procedures are immediately triggered to ensure that safety is preserved at all times.....
