Dormagen, Germany -- Bayer MaterialScience has been given the permit to build a world-scale 300-kilotonnes-per-annum plant for TDI (toluene diisocyanate). Bayer said 22 Feb that the Cologne regional administration has authorised its Euro 150 million ($198 million) project, and construction work can begin immediately. The final operating permit is expected in the spring.
"We are pleased that the construction for this important project can now begin and be completed within the next two years as planned," said Dr Joachim Wolff, head of the polyurethanes business.
"The future world-scale plant is the final building block of a long-term investment strategy in Dormagen in addition to being a key element for optimising our isocyanate production in Europe," Wolff added.
In the medium term, it will replace existing TDI plants of BMS in Dormagen and Brunsbuettel.
Bayer MaterialScience said it expects demand for this precursor for flexible polyurethane foams to continue to grow.
The new plant will use an innovative gas-phase phosgenation process which Bayer claims is "particularly efficient and climate-friendly. Compared with a conventional plant of the same size, the new facility will cut energy use by up to 60 percent while requiring as much as 80 percent less solvent.
According to BMS, the process "satisfies the most stringent of safety requirements." Safety measures include a continuously monitored, earthquake and stormproof housing. In theory, a variety of materials can be used for such a shell.
Bayer MaterialScience chose a metallic housing fastened to a stable steel base structure. In the unlikely event of a materials leak, this in combination with a robust ventilation system ensures that no substances escape the housing, protecting people and the environment.
