Deodorization tower is a device used to remove odors, volatile substances, and impurities from gases or liquids. It is widely used in various industrial fields, and its main application industries and scenarios are as follows:
1. Petrochemical industry
Crude oil processing: In the process of crude oil distillation, the deodorization tower can remove sulfides, volatile organic compounds (VOCs), etc. from light oils (such as gasoline and diesel), reduce oil odor, and improve product quality.
Chemical raw material processing: Processing chemical raw materials such as propylene and ethylene, removing odors and impurities generated during the polymerization process, and ensuring the purity of the raw materials.
2. Food and oil processing industry
Edible oil refining: In the refining process of vegetable oils (such as soybean oil and rapeseed oil), volatile substances such as free fatty acids, pigments, aldehydes, etc. are removed from the oil through a deodorization tower, eliminating the "oil flavor" and improving the flavor and shelf life of edible oils.
Dairy products and fermented foods: deal with odor gases (such as biogas and organic acid volatiles) generated during the fermentation process to improve the production environment and product odor.
3. Environmental protection and sewage treatment industry
Wastewater treatment plant: Treat the odor generated by anaerobic fermentation of wastewater (such as hydrogen sulfide, ammonia, etc.), purify the gas through deodorization tower (often using chemical absorption, biological filtration and other processes), and prevent environmental pollution.
Solid waste treatment: deal with the odorous gases generated by landfills and composting plants to reduce their impact on the surrounding environment.
4. Pharmaceutical and daily chemical industries
Pharmaceutical production: Remove volatile organic solvents (such as ethanol, acetone) and odor impurities generated during drug synthesis to ensure drug purity and safety.
Daily chemical products: In the production of detergent and cosmetics raw materials, the deodorizer can remove the unpleasant smell in the raw materials and improve the product use experience (such as the purification of essence and surfactant).
5. Energy industry
Natural gas processing: Removing odorous substances such as hydrogen sulfide and thiols (which are also corrosive components) from natural gas to meet the odor standards of civilian gas (usually requiring the addition of a small amount of odorant for leak detection, but excessive odor needs to be removed).
Biomass energy: Processing volatile gases generated during biomass gasification and pyrolysis processes, which can be purified and used as fuel gas.
6. Other industries
Paper industry: Dealing with odorous gases (such as sulfides) generated during the pulp making process to improve the workshop environment.
Coatings and adhesives: Remove volatile organic compounds (VOCs) from solvent based coatings and adhesives, reduce product odor, and comply with environmental standards.
