PCI Nitrogen announced Feb. 16 that on Feb. 13 in order to supply additional power to the Houston electric grid through its cogeneration facility, it elected to shut down ammonium sulfate production. On Feb. 15 due to the historical cold temperatures, the company was forced to shut all production at the facility which includes ammonium sulfate, sulfuric acid, ammonium thiosulfate and power production.
As of Feb. 16, the company said it is unable to say when the facility will return to normal operations and will depend on the weather moderating and raw material supply normalizing.
