Fertilizers

Technip has been is active in Fertilizers for decades through proprietary know-how and in association with leading technologies and the most reputed worldwide licensors.

Through the acquisition of KREBS-SPEICHIM in in the 1990’s Technip substantially improved its position adding  a first-class proprietary Phosphoric Acid technology and consolidated experience in Sulfuric Acid and Fertilizer plants.

The acquisition of SOFREMINES (now Technip Mines) in 2009 has allowed us to complement deep process design capabilities with know-how and experience in the field of Geology, Mining and Beneficiation of Phosphate Rocks
