1 Detection of catalyst concentration

II Detection of hydrogen peroxide concentration
Due to the extreme instability of hydrogen peroxide, it is easy to decompose into oxygen and water, while releasing heat and causing danger. Therefore, weak acids such as phosphoric acid are generally added to hydrogen peroxide. This will cause deviation in measuring hydrogen peroxide concentration using density and conductivity. The hydrogen peroxide bond in hydrogen peroxide only absorbs at specific wavelengths, so measuring hydrogen peroxide concentration using absorption method is not affected by temperature, pressure, and pH.
Application points and key elements:
1. Online monitoring of hydrogen peroxide concentration (0~35wt%) for purification tower discharge - Real time monitoring of hydrogen peroxide production efficiency and quality
2. Monitor the concentration of hydrogen peroxide (0-35wt%) before entering the ammonia oxime chemical process - Optimize the mixing ratio of the reactor feed
3. Extraction tower working liquid interface separation monitoring - saving hydrogen peroxide consumption (saving more than 12%)
4. Adsorption tower hydrogen peroxide concentration (0-1000ppm) - Safety production (methanol can only be used to regenerate the resin in the adsorption tower when the hydrogen peroxide concentration is less than 1000ppm, otherwise impurities in methanol can cause the decomposition of hydrogen peroxide and pose a danger)
5. Monitoring the concentration of peroxides in circulating water or wastewater - reducing the use of chemical treatment agents

III Detection of turbidity of hydrogen peroxide
There are certain requirements for turbidity in the production process of hydrogen peroxide, so real-time monitoring is needed

4 Detection of chromaticity of hydrogen peroxide working solution configuration
The ratio of 2-ethylanthraquinone in the working solution is abnormal. The physical parameter that reflects the concentration ratio is the chromaticity value. Accurately controlling the chromaticity of the working fluid can effectively prevent the induction of hydrogen peroxide decomposition and increase hydrogen peroxide production. Colorimetric configuration of hydrogen peroxide working solution (0-1.5CU)

5 Detection of chromaticity in hydrogenation purification
In the hydrogenation purification process, hydrogen peroxide requires strict control over the color of the products produced and purified from hydride production. Generally controlled within (0-100Hazen)
