| Abstract: | The technical know-how of tail gas washing system in large scale DAP plant is described, including the process, equipment and the characteristics of washing equipment. The innovation points and progressiveness of the technology are analyzed. With the high recovery rates of dust, fluorine and ammonia, 933 t ammonia plus 26 t fluorine are recovered each year in 600 kt/a DAP plant, the continuous operating cycle is prolonged to 15 days from 7- 10 days, equivalent increasing the yield of 10 000 t DAP. |
