How to deal with the odor in chemical plants?

⁣Three methods for deodorizing waste gas in chemical enterprises
There are three main methods for deodorizing industrial waste gas: chemical method, physical method, and biological method. Here is a detailed introduction:
1. Chemical deodorization method 🌀
Chemical washing absorption: Absorb odorous substances in exhaust gas through chemical solvents.
Combustion method: burn and convert odorous substances in exhaust gas into harmless substances.
Plasma deodorization: using plasma technology to decompose odorous substances.
Photocatalytic oxidation technology: converting odorous substances into harmless substances through photocatalytic reactions.
Ozone sterilization and deodorization technology for air microorganisms: using ozone for sterilization and deodorization.
Plant extract deodorization: Use plant extract to absorb and decompose odorous substances.
2. Physical deodorization method 🌍
Washing method: Absorb and separate odorous substances in exhaust gas through washing solution.
Masking method: Use masking agents to mask odors.
Adsorption method: Activated carbon, activated alumina, silica gel and other adsorbents are used to adsorb odorous substances, among which activated carbon is one of the most commonly used adsorbents and has good purification effects on most organic waste gases.
Condensation method: Using condensation technology to convert odorous substances into liquids or solids.
Dilution diffusion method: Dilute the exhaust gas and diffuse it into the atmosphere.
3. Biological deodorization 🌿
Biological deodorization is divided into three steps: water-soluble infiltration, biological absorption, and biological oxidation.
