2. DESCRIPTION OF THE PRODUCTION PROCESS 2.1 Basic Concept Phosphate sources must be converted into a form which can be taken up by plants ("avail-able"). This can be achieved by using the integrated "Nitrophosphate" process which pro-duces compound fertilizers containing ammonium nitrate, phosphate and potassium salts.

The fertilizer industry converts raw materials into three main types of fertilizers: nitrogen (ammonia), phosphorus, and potassium. These various applications call for chemical processes with precise control and accurate monitoring of temperature, pressure, level, and flow.. The global population is projected to reach 10.9 billion by the end of this century.
