A process for the preparation of nitrophosphate fertilizer by acidulation of phosphate rock by means of a mixture of HNO 3 and NH 4 HSO 4, wherein the NH 4 HSO 4, serves for the acidulation as well as for the precipitation of the calcium present in the phosphate rock as CaSO 4. 2H 2 O. The latter is treated with a gas mixture containing NH 3 and CO 2, forming CaCO 3 and (NH 4) 2 SO 4.
Aug 13, 2020· Nitrophosphate process Last updated August 13, 2020. The nitrophosphate process (also known as the Odda process) was a method for the industrial production of nitrogen fertilizers invented by Erling Johnson in the municipality of Odda, Norway around 1927.. The process involves acidifying phosphate rock with nitric acid to produce a mixture of phosphoric acid and calcium nitrate.

The nitrophosphate process (also known as the Odda process) was a method for the industrial production of nitrogen fertilizers invented by Erling Johnson in the municipality of Odda, Norway around 1927.. The process involves acidifying phosphate rock with dilute nitric acid to produce a mixture of phosphoric acid and calcium nitrate.. Ca 5 (PO 4) 3 OH + 10 HNO 3 → 3 H 3 PO 4 + 5 Ca(NO 3) 2 ...
Pak Arab fertilizers private Limited has been operating its nitrophosphate plant based on the ODDA process since 1978. The technology has been supplied by Stamicarbon Holland and engineering by ...
A primary advantage of this method is that little or no sulfur (S) inputs are required. With the nitrophosphate process, excess calcium from the phosphate rock converts to valuable calcium nitrate fertilizer instead of gypsum. Norway pioneered the nitrophosphate method, and much of the global production still occurs in Europe. The general ...

In a usual fertilizer production process, an average of two tons of carbon dioxide is produced per one ton of ammonia. Part of that carbon dioxide is captured during the production process of ammonia and used for commercial markets. Some companies have been using this practice for over 30 years. Removing carbon dioxide is done before nitrogen
The technology concerns the production of Water Soluble Granulated Calcium Nitrate, prepared from CNTH crystals as sub-product in ODDA type processes.
