摘要 |
An automatic continuous monitoring system for a chlorine dioxide generating process (10) which produces a gaseous mixture of chlorine dioxide and chlorine (12) is described. The automatic system eliminates the need for periodic manual analysis of the off-gas stream and enables changes in the process efficiency to be rapidly compensated for. The system preferably utilizes a gas-liquid chromatograph analyzer (36) to analyze the off-gases from the generator (10) and to provide signals (42, 44) corresponding to the measured amounts of chlorine dioxide and chlorine. These signals then are converted (46) to a signal (47) corresponding to the ratio of chlorine dioxide and chlorine in the off-gas stream. The ratio then is converted to the efficiency (48). The efficiency value so obtained (49) may be compared with a previously determined value and changes compensated for by catalyst and/or reactant feed variations. |
