A core product is 26% ammonium nitrate (with lime, brand name (later) Nitramoncal 26% ) as a nitrogen fertilizer for agriculture. Ammonia is oxidized to nitric acid, ammonia and nitric acid are neutralized to form ammonium nitrate, thickened with lime dust under vacuum and granulated while hot in rotating drums . For ammonia synthesis, nitrogen from the air separation according to Linde (the oxygen sometimes goes into the steelworks) and hydrogen from the coking plant of the steelworks are required .
  • The operation of the steel mill was stopped on May 5, 1945 at the end of the war .

The Norwegian group Hafslund Nycomed took over 55% of CL Pharma AG (1991: 100%)
  • In 1991 Chemie Holding AG was converted into a GmbH and merged with Chemie Linz Ges.mbH; “Agrolinz Agrarchemischem Ges.mbH” is therefore a wholly owned subsidiary of Chemie Linz Ges.mbH, which acted as the lead company for the chemistry division of ÖMV AG.
  • In 1993 Agrolinz Agrarchem Nahrungsmittel Ges. Mb H. was merged with Chemie Linz Ges.mbH as the receiving company.

  • In 2005 OMV sold 50% of its shares to IPIC , which itself has a 17.6% stake in OMV.
Heavy smoke development in the fire in the NPK fertilizer plant in 2007

Shift work

The Linz plant works around the clock in eight-hour shifts. The so-called 5-shift system is used in Linz.

When the shift changes, numerous so-called “shift buses” run from the Chemiepark bus stop to the surrounding communities in Linz, although non-employees can get on and off at the bus stops, several of which are already in Linz.
