| Abstract: | Aiming at 290 kt/a DAP or 300 kt/a NPK, a 240 kt/a ammonium phosphate facility with the process of preneutralization, drumammoniation, is improved by the application of singlepipe reactor. Some information are presented on the equipment and processes of granulation, drying, cooling, dedusting before and after the improvement, on the effects of the improvement (higher productivity, better environment etc.) , some problems and their solutions such as the overcharge of fluorine, higher moisture in product, etc. |
