History

The Frank–Caro process was the first commercial process that was used worldwide to fix atmospheric nitrogen. The product was used as fertilizer and commercially known as Lime-Nitrogen. Nitrolim or Kalkstickstoff in German.[1] The method was developed by the German chemists Adolph Frank and Nikodem Caro between 1895 and 1899. In its first decades, the world market for inorganic fertilizer was dominated by factories utilizing the cyanamide process.

Production facilities

UNESCO World Heritage List.[2]

Haber process

In the 1920s the more energy-efficient Haber process gradually took over. In 1945 the production of calcium cyanamide reached a peak of an estimated 1.5 million tons a year.[3]
