Krefeld/Germany – Yesterday's groundbreaking ceremony at Krefeld was the beginning of a planned doubling of capacity at Krefeld-Uerdingen to meet the increasing world market demands. "The additional quantities of thymol, crude menthol and D,I-menthol will allow our long-time contract partner Symrise to enter into long-term supply agreements," said Dr. Hubert Fink, head of Lanxess' Advanced Industrial Intermediates business unit. The project is expected to be completed by the first half of 2012. Lanxess produces menthol and thymol for Symrise, a major producer of flavors and fragrances in Holzminden/Germany. Symrise CEO Dr. Heinz-Jürgen Bertram also attendended the groundbreaking ceremony in Krefeld.

The major raw material cresol stem from the own production network on the Lower Rhine. An new energy recovery unit will be installed to further improve the energy balance (CO2 footprint) for menthol. As part of the construction project, three large distillation columns will be erected in fall 2011. The largest will be about 50 meters tall and it was designed specifically for this purpose. "A column of such dimension is special for our plant," said production manager Dr. Lutz Heuer. Assembly of the enormous structural elements will begin once they have been delivered to their destination in Uerdingen – an operation that will require special transportation as a heavy load. "We will use three cranes, one of which has a lifting capacity of 900 metric tons and is the largest available in Germany. It will also enable us to lift the heaviest single element, which weighs 90 metric tons," said Heuer.
