High energy consumption can be a big expense when producing water soluble MAP (mono-ammonium phosphate). The central part of the CleanMAP technology is to extract phosphorus from P streams in the form of pure, solid and water-soluble phosphate salts (MAP, DAP) in a cost-effective way. We promote three main benefits of the Clean MAP process:
Reduced capital costs
The CleanMAP technology renders entire plant sections to be unnecessary such as evaporators, steam distribution systems, condensation systems, effluent gas treatment systems, cooling water systems, and acid storage facilities. Capital costs for the new technology are lower than excluded plant sections.
Reduced operational and maintenance costs
Reduced operational costs are mainly due to exclusion of the need for steam for acid concentration, and no need for complex effluent gas treatment. Reduced maintenance cost is mainly achieved due to the absence of sludge and scale removal from evaporation systems.
Quality difference – technical grade vs. fertilizer grade
The CleanMAP technology enables direct production of MAP or DAP of technical grade. Separation of pollutants such as cadmium, uranium and fluorine is achieved. The products are well defined and completely water-soluble. Phosphorus concentration is about 20 percent higher than in ammonium phosphates of fertilizer grade.
