Production of 450,000 MT/Year Diammonium Phosphate by Jacob’s Slurry Process

Abstract

Fertilizers have been in use long before the modern industrial processes came into being. Traditionally, cow manure and other natural remains have remained an important part of agricultural practices to provide Nitrogen and continues to be used in various parts of the world even today. The importance of Phosphorus however was discovered in the early 1800s. Phosphorus is a key part of cell growth and is a constituent of plant DNA which is responsible for specifying cell function and replication. It is also crucial for root development and flowering. Traditionally, bones were used to provide phosphorous to plants until the 1960s when the first commercial technology the TVA process was developed. The TVA process was replaced with the Jacob’s slurry process in the recent years due to increased efficiency, lower lost and better process sophistication, and control.
