The document provides flow diagrams of typical NP processes and discusses some challenges with the traditional NP process. The document describes the nitrophosphate (NP) fertilizer …

Typical Odda Nitrophosphate Flow Diagram. 203 phosphate rock with nitric acid raises the temperature of the solution to 50°-60°C. When the solution is cooled to 15°-20°C, about 60% …

Odda Process. Initially, rock phosphate is digested with nitric acid. Calcium nitrate is removed by crystallization from the NP solution, which is neutralized by addition of gaseous ammonia. To …

Production of nitro phosphate by ODDA Process involves the following steps. 1) Acidulation of Phosphate rock with 60% HNO3. 2) Crystallization of Ca (NO 3) 2 to Ca (NO 3) 2.4 H 2 O. 3) …

A process flow chart of the reaction of the ODDA process is shown in Figure 1. The ODDA process involves acidifying phosphate rock with dilute nitric acid to produce a mixture of...

Jan 1, 2012 · 2. Nitrophosphate Complex The Nitrophosphate complex of PFL operates on basic ODDA process licensed by Stamicarbon, Holland and detailed engineering by Udhe, …

This can be achieved by using the integrated “Nitrophosphate” process which pro- duces compound fertilizers containing ammonium nitrate, phosphate and potassium salts. This …

One of the possible processes to do this is the so-called nitrophosphate process or ODDA process. In the ODDA process, all nutrient components are used to produce nitrate-containing …
