| Abstract: | The acidulation and filtration systems of phosphoric acid unit in Guixi Chemical Fertilizer Co., Ltd.and their scaling status are described.By analysis, the scaling in vacuum room of filter and on inlet pipe of pump for diluted phosphoric acid is thought of the main cause restricting the systems' running rate.The measures are given with steam leaded into vacuum room and inlet pipe of pump, and keeping the heat around inlet pipe of pump well, which results in an increase of 3 percentage points for running rate. |
