Fertilizer Production Expertise HPD® Evaporation and Crystallization

WATER TECHNOLOGIES Expertise Case Study: Veolia NPK HPD® Evaporation and Crystallization systems from Veolia Research & Development NPK Process Capabilities Water Technologies provide innovative process solutions for large-scale fertilizer production facilities worldwide. IC Corp. (ICP) - of Potash (SOP) These systems allow production of a wide range of high-quality fertilizer products from natural sources (mined or solution mined deposits) or by-product streams from other processes that include: Chlorine / • Ammonium sulfate • Mono phosphate Raw Materials Natural Gas Sulfur Phosphate Rock Hydrogen Gas Potash Source • Ammonium nitrate (MKP) • (MOP) • Sodium nitrate • (SOP) • Phosphoric acid merchant/ technical/food/electrical • Monoammonium phosphate (MAP) grade ICP's Ochoa Mine project (New Mexico, USA) is • Diammonium phosphate • Potassium carbonate (DAP) • Potassium nitrate projected to produce approximately 714,000 TPY Ammonia Plant Sulfuric Acid Rock Grinding Hydrochloric Acid of Sulfate of Potash (SOP-K SO ) from • Epsom salt: • Calcium phosphate 2 4 Plant Plant Plant ore (K SO .MgSO .2CaSO .2H O) for more than 50 sulfate heptahydrate • Calcium sulfate 2 4 4 4 2 years. • • Calcium chloride monohydrate Veolia was selected to refine, confirm, and validate the overall ICP process utilizing HPD® Evaporation and Crystallization technologies through a series of bench and pilot-scale testing programs performed in Veolia’s in-house testing facility.

The scope of the testing extended lants from the ore P leaching to the SOP crystallization process including Nitric Acid Plant Phosphoric Acid PlantPotassium Chloride Plant

crystallization/redissolution of leonite (K2SO4.

MgSO4.4H2O), and calcium sulfate removal. As a "first-of-kind" process, the challenge was to develop a cost-effective process to produce a premium potassium sulfate fertilizer. The series of tests proved to be a success as the produced Phosphoric SOP achieved the purity, crystal size, and habit Ammonium Ammonium Ammonium Acid Phosphoric Di-Calcium Potassium Conversion Potassium requirements for a fertilizer application.
