Use of local rock phosphate to manufacture Di-Ammonium Phosphate

Abstract

The document provides information about the work that was done on the process design of a Diammonium Phosphate Plant. With the growing economy and fast paced motion of the world towards more economically efficient and environmentally friendly processes, our design gives the best possible solutions for the local market requirements. Our design utilizes the local resources and therefore minimizes imports and extra logistical costs. Similarly it utilizes the use of latest software technology to test the validity and efficiency of our process through Aspen Tech Simulations. The traditional processes being used have been described and the problems they faced which make them less desirable have also been studied. The main raw material involved is phosphoric acid which was previously imported, would now be produced within the country due to our process design and therefore, minimizing extra costs. With our process, we plan to reduce the cost of 50 kg DAP bag from $ 23 to $19. Our process also utilizes all the energy streams very efficiently making it a highly energy and cost efficient plant.
