Brussels—Tessenderlo Group reports that construction work on Tesssenderlo Kerley Inc.’s (TKI) two new ammonium thiosulfate plants (Thio-Sul ®) in East Dubuque, Ill., and Rouen, France (GM Nov. 3, 2014; May 11, 2015), are both expected to be complete in second-half 2017. The East Dubuque plant is adjacent to the CVR Partners LP (formerly Rentech Nitrogen LP) nitrogen complex, and will receive ammonia from that plant. Borealis will supply ammonia to the French plant. The East Dubuque completion date has been pushed back from earlier estimates. Tessenderlo also expects to complete a new electrolysis plant in Loos, France, in second-half 2017. The company has announced the startup of a new sodium hydrosulfide (NaHS) plant in Billings, Montana, within its joint venture Jupiter Sulphur LLC.
