Online analysis and removal of chlorine dioxide

Regarding clause 4.2.17 of the \"Safety Design Standards for Caustic Soda Plants\", which states that \"there should be measures to dilute chlorine dioxide in the gas phase area at the top of the chlorate decomposition tank\", what is everyone’s understanding of this statement? Which company’s process technology is being used?
This clause means that there should be a way to reduce the concentration of chlorine dioxide at the top of the chlorate decomposition tank to ensure safety. This is usually achieved through dilution or chemical reactions. The specific process technologies may include gas absorption, neutralization, or catalytic conversion, etc. Different chemical plants may choose different technical solutions based on their own safety standards and efficiency requirements, such as introducing fresh air for dilution or using catalysts to convert chlorine dioxide. Which specific technology to use depends on the actual conditions of the equipment and the market situation of the suppliers. .
