| Abstract: | The preparations of hydrogen fluoride gas,distillation of crude product,desorption of the SO2 and SiF4 as well as the rectification of liquid hydrogen fluoride were comprehensively analyzed in the process of preparing AHF with fluorite-sulfuric acid method.The factors influenced on the quality and yield of AHF product,such as the pretreatment of material,the concentration,mixing proportion,moisture and the management of production processes,were mainly studied,and the corresponding solving methods were put forward.Finally,the development of AHF production processes was prospected. |
