Oklahoma City-LSB Industries Inc. said Oct. 24 that its subsidiary, El Dorado Nitrogen LP, has completed its renewal and extension discussions with Bayer MaterialScience LLC and will continue its strategic supply relationship into the next decade. The new five-year agreement provides for El Dorado to supply Bayer with its total requirements for nitric acid at its Baytown, Texas, polyurethane intermediates complex. The El Dorado facility is a world-class nitric acid manufacturing facility capable of producing more than 475,000 tons of nitric acid each year. “We are proud to be chosen by Bayer to continue working with them at their world-scale Baytown complex,” said Jack Golsen, LSB chairman and CEO. “Bayer and our LSB chemical business operations have had an excellent business relationship over these past ten years, and we look forward to working together in the future.” Separately, Cherokee Nitrogen Co., a subsidiary of LSB’s chemical business, also announced the extension of its ammonium nitrate supply requirements agreement with Nelson Brothers LLC for its emulsion plant on the Cherokee, Ala., site.
