Highlights:
1927 | The "Titangesellschaft mbH" was founded as a joint venture of IG Farben and Titan Co. AS for the production of TiO2 by means of the sulfate process. The plant was built as a part of the Farbenfabriken BAYER. |
1928 | Production of pigment and Titanweiß (TiO2 + BaSO4) started. |
1930 | Production capacity increased to 11,700 mt per year. The TiO2 produced was originally the anatase modification of TiO2 only. |
1938 | Became the world's first plant to produce the rutile modification of TiO2 (based on our own patent). |
1943 | During World War II, 80% of the plant was destroyed |
1945 | The plant was rebuilt and production restarted. |
1952 | NL Industries took over the remaining shares of the "Titangesellschaft" from the joint-venture and became sole owner of the company. |
1967 | The first TiO2-production unit using chlorine technology in Europe was built - based on KRONOS process developments and patents. |
1972 | "Titangesellschaft mbH" changes to "KRONOS TITAN GmbH" |
1974 | Start of copperas production |
1975 | A new generation of chloride unit was designed and built. |
1979 | The FERRIFLOC unit was built, to produce FeClSO4 from Copperas. |
1984 | Start-up of KRONOCARB production |
1985 | Launched a second chloride production line. This line was the blue print for the construction of all other KRONOS Chloride plants. |
1989 | Start-up of a waste acid reconcentration unit in Duisburg in cooperation with Sachtleben Chemie GmbH |
1992 | Start-up of the calciner's off-gas desulfurization unit (Sulfate plant) |
1995 | Start-up of the KRONOFLOC production |
1996 | Start-up of Ilmenitsand production |
2002 | The desulfurization unit for the chlorinator off-gas from the chloride plant was comisioned. |
2012 | Increased chloride unit production capacity to 165,000 mt per year by constantly improving, optimizing and debottlenecking. |
