| Abstract: | Measurement principle and structure of online sulphur dioxide analyzer using UV spectrophotometry are described.The analyzer has some advantages,including high sensitivity,good selectivity,wide measuring range and real-time online measurement.The analyzer has been applied in some sulphur-burning sulphuric acid plants for tail gas online detection,such as Zhangjiagang Shuangshi Fine Chemicals and Saudi Arabia’s PRIME BASIC CHEMICALS PVT.The results in long-term use showed that the analyzer got an error of no more than 1.0% FS compared with the measured values by chemical analysis and could meet user’s requirements. |
