8.5.2 Triple Superphosphates 8.5.2.1 General2-3 Triple superphosphate, also known as double, treble, or concentrated superphosphate, is a fertilizer material with a phosphorus content of over 40 percent, measured as phosphorus pentoxide

Phosphate is a key component in sustaining healthy and productive crops. While most phosphate rock goes to the production of MAP and DAP fertilizers, this life-giving mineral can be made into a variety of fertilizer products and blends through the process of granulation. FEECO has been a leader in the fertilizer industry since 1951.

A process is disclosed for the manufacture of granular diammonium phosphate (DAP) by reacting anhydrous ammonia with phosphoric acid in a reactor to form reaction product consisting of a partially reacted slurry of monoammonium phosphate and diammonium phosphate. The slurry is pumped to a rotary granulator-reactor where it is further reacted with anhydrous ammonia to form a solid granular ...

Many commercial detergents also contain phosphate compounds. This can be a problem, because phosphate is a nutrient for plants. Too much phosphate in a pond, lake, or stream accelerates the growth of algae, which consumes too much of the dissolved oxygen in the water. This disturbs the ecosystem in the pond, and some organisms will die.

production of these chemicals increased strongly and growth leveled off in the nineteen-eighties. This source now accounts for 60-70% of the AS produced in the world. Other sources for ammonium sulfate are for example the purge of gas wash-ers e.g. from large urea prilling towers or regeneration liquids from continuous ion exchange systems.

available phosphate (P 2O5) and soluble K 2O. The grade of a fertilizer is expressed as a set of three numbers in the order of percent N, P 2O5 and K 2O. If a nutrient is missing in a fertilizer, it is represented by a zero. Thus ammonium sulphate is represented by 20.6-0-0.

Economical and with high nutrient content, ammoniated phosphates such as mono- and di-ammonium phosphate (MAP, DAP) are another popular choice of fertilizers. They are obtained when ammonia (liquid or gaseous) is added to the weak phosphoric acid. Phosphate fertilizers production flow-cart can be illustrated in the following figure :
