the dry kiln process phosphoric acidThe fouling properties of SiO2 CaO P2O5 system in high
Manufacturing Process Phosphoric acid is usually produced by three commercial methods including wet process thermal process and dry kiln process Among these three methods wet process is the most common route The phosphate first reacts with the recycled phosphoric acid from the process and then mixed with sulfuric acid as a leaching agentKiln phosphoric acid KPA technology could produce P 2 O 5 with high purity and has been applicated in thermal phosphoric acid industry however the formation of fouling in the high temperature rotary kiln restricts the stable and long term operation In this paper the reaction of phosphate ores with gaseous P 2 O 5 was investigated in a high temperature reactor and the CaO SiO 2 P 2 O 5
