The organic waste gas produced in the production process of the extraction workshop is mainly composed of extractant and solvent oil. It has high volatility, flammability and certain toxicity, which will pollute the atmosphere. This paper introduced the ventilation technology currently used in the extraction workshop, and focused on the principles, devices and adaptability of commonly used organic waste gas treatment schemes, such as purification tower-activated carbon adsorption scheme, RTO regenerative combustion scheme, polymer material absorption + steam regeneration scheme, etc., and gave suggestions on the selection of organic waste gas purification schemes according to the actual situation.
