Koch Fertilizer building ammonium thiosulfate terminal at Fort Dodge facility

Koch Fertilizer (KF) is building a 2 million gallon ammonium thiosulfate (ATS) terminal at its Fort Dodge facility in Iowa, US, to support growing demand.

The ATS storage tank will feature insulation and an internal coating to enable winter storage and tank reliability. It also will tie into the existing automated urea ammonium nitrate (UAN) loadout infrastructure, providing the ability to mix ATS with UAN or water in a single truck for customised fertilizer blends — without impacting current UAN loadout ability. The terminal will support 24-hour loading and will load a truck in approximately 20 minutes.

With the additional storage and loading capacity, KF will be able to supply more customers throughout the Corn Belt with ATS produced by Koch affiliate, Flint Hills Resources. KF markets 100% of the ATS Flint Hills Resources produces at its Pine Bend refinery, approximately 100 000 short tpy.

“In the last few years, retailers and farmers have had difficulty finding adequate supply of ATS, and at the same time demand continues to grow,” said Scott McGinn, Koch Fertilizer executive vice president. “By building on our relationship with Flint Hills Resources and our terminal expertise, we can provide additional ATS capacity to the region and better serve our customers into the future.”

The terminal will be commissioned and operational in December 2021. This project builds on the US$140 million Fort Dodge expansion announced in November 2020.
