Abstract
A novel process was developed for production of high analysis fertilizers in which large portions of the nutrients are derived from by-product and waste ammonium sulfate. The materials produced exhibit good physical and storage characteristics and are similar in grades to those now being consumed in large quantities. Phosphoric acid and anhydrous ammonia are reacted to form the liquid bonding agent. Solid ammonium sulfate, potassium chloride and recycled fined are added to the melt in a pug mill. Emissions of pollutants is less than from conventional plants and is readily contained. The process was developed and tested on a laboratory scale and in a small pilot plant and was verified in a 454 kilogram per hour (1000 pound per hour) demonstration unit. Capital and operating cost estimates are presented. The operating cost is sensitive to the assumed value of waste ammonium sulfate. In comparison to similar grade products, cost savings of 10 to 20% can be realized if true waste values can be assumed. The financial estimates did not attempt to evaluate the indirect benefit to society, in terms of dollars and of energy, of recovering waste ammonium compounds and sulfur dioxide---which often are discarded into aquifers or into the atmosphere and thus constitute major pollutant threats---and of converting these chemicals into useful products.
