Ji'nan oil and gas recovery and treatment 631 gas stations will say goodbye to "gasoline flavor"
Ji'nan times
oil / > oil at the gas station Before the gas recovery, the pungent smell of petrol used to be the label of the gas station. Reporter learned from the Spring City Environmental Protection Century activities, in July last year Ji'nan launched a comprehensive oil storage tank, gas station, oil tank car oil and gas recovery management, as of now completed 529, this year, before the end of June this year, the city's 631 gas stations will all achieve oil and gas recovery, farewell gasoline taste.

8000 tons of oil and gas pollutants in Ji'nan each year, Qin Lihua, deputy director of the Municipal Environmental Protection Bureau, said Qin Lihua, the reservoir, gas station and tank car will discharge a large amount of oil and gas pollutants into the atmosphere in the process of storage, transportation and sales. Oil and gas pollutants are mainly composed of volatile organic compounds such as hydrocarbons. Many oil and gas pollutants are harmful to human body, and some of them have carcinogenic effects. It is introduced that volatile organic compounds are converted into ozone (O3) and fine particles (PM2.5) in the air. It is the precursor of PM2.5, and it may become an important condition for the formation of photochemical pollution and haze. According to statistics, the amount of oil and gas discharged into the atmosphere from production to sale of gasoline is about 8 kg / ton. The annual emissions of oil and gas pollutants are about 8000 tons, according to the calculation of 1 million tons of gasoline consumed by the whole city. Qin Lihua said that through the recovery of oil and gas, the oil and gas that volatilized into the air will be collected during the process of loading and unloading gasoline and refueling vehicles.
in July last year, Ji'nan started the comprehensive management of oil and gas recovery in oil storage tanks, gas stations and oil tanks. Up to now, our city has included 631 gas stations in the investigation area, and 529 oil and gas recovery and transformation have been completed. In addition, 373 oil tankers have been transformed and 8 oil storage depots have been started and transformed, and half of them have been completed.

ten thousand yuan refueling gun has a trap, catch the escape of oil and gas
22 morning, reporter arrived at the ten road of Sinopec Ji'nan 177th gas station, standing next to a car being refueling, the whole process of refueling, almost no smell of gasoline. According to the staff of the gas station, the gas gun in his hand is reformed and looks like the ordinary gas gun. It can give oil and gas to hold, relying mainly on two traps.
reporter noticed that at the front of the fuel gun, there was a steel sleeve and a rubber sleeve on it. Don't belittle this unattractive refueling gun. The price is about 10 thousand yuan.
Liu Yudong, deputy director of the management department of the Sinopec Ji'nan branch, said that the oil and gas recovery of the gas station is a system project, and the gas gun is only a detail. The oil and gas recovery system of the gas station consists of two parts: one and two oil and gas recovery. Liu Yudong said that the oil gas recovery means that when the oil tank truck is unloaded, the gasoline is unloaded from the tank car, the pressure of the tank is increased, the pressure of the tank car is reduced, the oil and gas in the tank are pressed into the tank car through the back gas pipeline under the pressure of pressure, and the amount of unloading oil and the recovery of the oil and gas ratio can reach 1:1.2. The two recovery is the oil and gas recovered by the oil gun, and the pump is returned to the oil tank.
it is understood that, like Sinopec Ji'nan 177 station, a total of 8 gasoline refueling machines and 8 gasoline guns were retrofit, and the single station transformation investment was 330 thousand and 500 yuan.

poor recovery of oil and gas, the costs involved in the upgrading and upgrading of the 8 gas stations for
oil and gas recovery are all borne by the related enterprises, and the social responsibility of the enterprises on environmental issues is tested. According to the regulations on the prevention and control of air pollution in the city of Ji'nan, the facilities and places where the oil and gas storage facilities, such as storage tanks, gas stations and tankers have not installed oil and gas recovery units in accordance with the relevant regulations of the state and the province, shall be ordered to stop using the oil and gas units and make corrections within a period of time and can be punished with a penalty of less than ten thousand yuan and fifty thousand yuan. It is reported that 8 gas stations are not punished according to the regulations and are punished accordingly.
urge oil and gas recovery as soon as possible, and Ji'nan play a combined boxing. According to the regulations, the installation of oil and gas recovery facilities for the newly built or modified (expansion) station has not been installed according to the requirements of the oil and gas recovery facilities. The approval certificate for the operation of finished oil will not be issued in July 1st this year, and the oil and gas recovery treatment equipment for the existing gas stations is not installed, and the approval certificate of the finished oil operation will not be approved at the annual qualification examination.

5 months of Ji'nan's primary pollutant last year was the ozone
reporter learned a little surprise from the city environmental protection agency that last year Ji'nan had 5 months, the primary pollutant was not PM2.5 or PM10, but.Amp; mdash.amp; mdash.amp; mdash O3 (ozone).
the Municipal Environmental Protection Bureau said that the main pollutants are mainly concentrated in summer and autumn, in May, June, July, August and September, respectively. It is understood that O3, like PM2.5, is the two pollutant. At the height of 20 to 30 kilometers from the surface, ozone is beneficial, which prevents the sun's ultraviolet radiation from endangering the natural barrier of the earth's organisms, but on the ground, it can harm the health of the human body.
O3 is a trace gas in the atmosphere of the earth. After the oxygen molecules in the atmosphere are decomposed into oxygen atoms by the solar radiation, oxygen atoms are combined with the surrounding oxygen molecules. In addition to natural production, automobiles, coal-fired and petrochemical industries are all major sources of ozone pollution. O3 is not directly emitted by pollution sources, but is the two pollutant formed by the reaction of oxygen, nitrogen oxides and volatile organic compounds under the action of sunlight. From May to September, sufficient illumination in Ji'nan created conditions for O3's "attack".
in addition, the reporter understands that the EPA is working with Nankai University to study the source apportionment of PM2.5 in our city. According to preliminary studies, the total contribution rate of dust, coal dust and motor vehicle exhaust to PM2.5 in our city is 60% to 70%.

3981 previously abandoned Yellow standard vehicles received subsidies
Environmental Protection Bureau hair initiative: "yellow standard bus" should be eliminated as soon as 11:00 on the 22 day at 11:00.
