This is the latest unique technology in the world developed by the Asia Chemical, it is completely different from the current yellow phosphorus thermal phosphoric acid process and wet phosphoric acid process. It adopts dynamic wave thermal reaction technology. It’s no need to produce yellow phosphorus from phosphate rock first and then produce phosphoric acid from yellow phosphorus, similarly, it’s also not the wet process phosphoric acid production which use the strong acid to decompose phosphate rock, and generate a large amount of pollutant phosphogypsum. In our dynamic wave thermal phosphoric acid production technology, phosphate rock, coke, silica and other raw materials are directly fed into the dynamic wave reactor to complete the reduction and oxidation reaction. The heat source required for the reaction is natural gas or coal gas. The P2O5 gas produced by the reaction can generate high quality phosphoric acid with concentration 85% after being absorbed and hydrated by the absorption tower, and the whole production will not produce pollutants such as phosphogypsum.
