The hydrogen peroxide coalescer is mainly used in the production process of hydrogen peroxide and related wastewater treatment processes. By separating impurities, moisture, and organic matter, it ensures product quality, improves production efficiency, and reduces environmental pollution. The specific applications are as follows:
1. Working fluid treatment in the production process of hydrogen peroxide: After hydrogenation, oxidation, and extraction processes in hydrogen peroxide production, a certain amount of water will be carried in the feed liquid at the top of the extraction tower. The hydrogen peroxide coalescer can separate the water in the working fluid, prevent catalyst deactivation in the hydrogenation unit, and achieve the recycling of the working fluid, reducing the use of alkali solution.
2. Purification of crude hydrogen peroxide: Crude hydrogen peroxide often contains impurities such as organic compounds. The hydrogen peroxide coalescer can remove these organic compounds before distillation to purify the hydrogen peroxide solution and ensure product quality.
3. Oil removal of dilute hydrogen peroxide: Dilute hydrogen peroxide will carry a certain amount of oil phase. Through a coalescer, the turbid dilute hydrogen peroxide solution can be made clear and transparent, and free and emulsified oil can be basically removed, achieving the purpose of purifying the product and reducing the use of back-end oil removal resin.
4. Oxidation of tail gas to remove aromatic hydrocarbons: During the oxidation process of hydrogen peroxide production, the tail gas will contain aromatic hydrocarbons. The hydrogen peroxide coalescer can treat the oxidation tail gas, recover the aromatic hydrocarbons, and achieve resource reuse while reducing pollutant emissions.
5. Hydrogen Dehydration: Hydrogen, as a raw material or related gas in hydrogen peroxide production, may contain moisture. The coalescer can dehydrate and purify the hydrogen to ensure its purity, which is beneficial for the stable operation of subsequent processes.
6. Treatment of hydrogen peroxide production wastewater: The wastewater discharged from the anthraquinone production of hydrogen peroxide contains organic compounds such as heavy aromatic hydrocarbons, trioctyl phosphate, alkyl anthraquinone, and their degradation products. The hydrogen peroxide coalescer can separate these organic compounds from the wastewater, reducing the pressure of subsequent biochemical treatment and minimizing environmental pollution.
