On June 9th, Li Yunbao, an employee of the fuel station in the first workshop of Dalian Petrochemical, received the test results of the newly commissioned diesel oil and gas recovery device. "We are the first diesel oil and gas recovery device in China. The removal rate of non-methane hydrocarbons reached 99.97%. !" After 70 days of construction, the first domestic diesel oil and gas recovery unit was officially put into operation in Dalian Petrochemical Company.
The fuel station of the first workshop of Dalian Petrochemical Company currently has 10 diesel loading cranes, and the maximum loading capacity per unit time is 500 tons per hour. Regardless of the fact that the complete set of diesel oil and gas recovery equipment at the fuel station has only two 30-cubic-meter "small tanks" and two vacuum pumps, they have played a big role in the process of diesel loading and emission reduction. The device adopts the combined process of "activated carbon adsorption + vacuum desorption regeneration". The activated carbon tank recovers and adsorbs the oil and gas generated by diesel loading, and then uses a vacuum pump to analyze and regenerate the activated carbon rich in oil and gas in the adsorption tank and send it to the gasoline oil and gas recovery device. The activated carbon can be used repeatedly after regeneration.
"The seemingly simple process has made up for the industry's blind spots in the recovery and treatment of domestic diesel oil and gas, and effectively solved the problem of unorganized emissions of diesel oil and gas!" Speaking of the diesel oil and gas recovery device built by himself, Wu Sheng, the station chief Very proud. As the "veteran" in the construction of the tank farm of Dalian Petrochemical Company, Wu Sheng experienced the completion of the first gasoline online blending device in Asia organized by Dalian Petrochemical Company, the first domestic diesel online blending device, and the company's first membrane absorption gasoline vapor recovery device. use. Wu Sheng said with emotion, "Over the years, watching the company continue to reform and innovate clean and safe production technology, it has also witnessed the company's efforts and development in green environmental protection work!"
Since the "Thirteenth Five-Year Plan", Dalian Petrochemical Company has adhered to the principle of "grasping the source, controlling the middle, controlling the end, reducing the quantity and making resources", and actively fulfills its social responsibilities. The company continues to improve the ecological environmental protection management system, vigorously promotes the application of advanced technologies for environmental protection, energy saving and emission reduction, and implements a large number of environmental protection projects such as oil quality upgrades, environmental protection pollution prevention, energy saving and consumption reduction and emission reduction, including COD, nitrogen oxides, Compared with the end of the "Twelfth Five-Year Plan" period, sulfur dioxide has been reduced by 23%, 53%, and 85%, respectively. It has been rated as an "Environmental Integrity Enterprise" in Liaoning Province for many years. The effect of VOCs governance has been affirmed and recognized by the research team of the Ministry of Ecology and Environment.
