Oslo — Yara International ASA said Dec. 5 that its board of directors has approved a $220 million investment to sustain and increase technical ammonium nitrate (TAN) capacity at the Köping site in Sweden. This includes the construction of a new nitric acid plant to replace an existing plant that is approaching the end of its operating life. The total TAN capacity after the upgrade will reach about 450,000 mt/y. "With this investment, Yara further strengthens its position as the largest independent supplier of high quality TAN globally. After the expansion, Köping will be well positioned to efficiently supply growing demand in Nordic markets, as well as continuing to supply global markets," said Torgeir Kvidal, Yara president and CEO. Construction will start in 2015, with completion expected in second-half 2017.
