    Phosphoric acid is produced by Thermal process—Put the melting yellow phosphorus into the burning tower and burn it with oxygen ,which will produce phosphorous pentoxide . The phosphorous pentoxide together with water become phosphoric acid,then add catalyst to dearsenify .The flowing are filtration¡¢desaeration and packing¡£
