Show FIRST IN AMERICA I - " j The chemistry of coal yields a rich harvest in high-grade nitrogen fertilizers at the new Nitrogen Plant at U. S. Steel's big Geneva Works, near Provo, Utah, first of its kind at a major steel mill in the United States. At this chemical plant, coke oven gas from steelmaking operations is converted into anhydrous ammonia which is stored in the two big hortonspheres (right). Some of the anhydrous ammonia goes to produce ammonium nitrate. This nitrogen-rich fertilizer is converted into solid form as prills in the 13-story prilling tower (left). Ammonium sulfate, a third member of the USS fertilizer family, is turned out in another section of Geneva's coal chemicals producing facilities. |
