| Abstract: | The mathematical model and scalingup design were studied for ammoniator with external circulation . Result shows that the flow model of the reactor approaches to perfect mixed flow at industrial conditions. The model of mass transfer is k \-\{ G \}a=20 G a \ \{0.3\} q a \ \{1.2\}(pH)\ \{-2.1\}. Based on the model, the ammoniator has been scaled up to an industrial reactor with the capacity of 60 kt/a MAP and 160 kt/a DAP, and are well operated. |
| Keywords: | reactor with external circulation mathematical model scaling-up design ammonium phosphate |
