before oil and gas recovery at the gas station, the pungent gasoline taste was once refueling The "label" of the station. Reporters recently learned from the Ji'nan Environmental Protection Bureau, by the end of June this year, the city's more than 600 gas stations will achieve oil and gas recovery, farewell to "gasoline flavor."
annual emission of oil and gas pollutants is about 8000 tons
"oil and gas pollutants are mainly composed of volatile organic compounds such as hydrocarbons, and some of them are carcinogenic." According to a person in charge of the pollution control department of the Ji'nan Environmental Protection Bureau, the reservoir, gas station and tank car will discharge a large amount of oil and gas pollutants into the atmosphere during storage, transportation and sales. Volatile organic compounds are converted into ozone and fine particles in the air, which are precursors of PM2.5 formation. In serious cases, it may also 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. According to the calculation of 1 million tons of gasoline consumed by the whole city, the annual emission of oil and gas pollutants is about 8000 tons.
"in the process of loading and unloading gasoline and fuel to the vehicle, the oil and gas that volatilized into the air, not only save the resources, eliminate the odor of oil and gas, but also improve the quality of the air." The person in charge said.
in order to effectively control the emission of oil and gas pollutants, according to the requirements of the state and Shandong Province, Ji'nan city started the comprehensive treatment of oil and gas recovery in oil storage tanks, gas stations and oil tanks in July 2013, and issued the "Ji'nan oil and gas recovery management work plan" and "Ji'nan environmental protection system oil and gas recovery treatment". In August 1st last year, we held a mobilization meeting for the comprehensive management of oil and gas recovery in the city.
as of June 6th this year, the whole city completed the oil and gas recovery and renovation of the oil storage tank 4, the completion rate of 50%; 600 gas stations, the completion rate of 95%; oil tank car 272, the completion rate of 100%. There are 3 oil storage depots and 1 gas stations currently under construction. There are 1 unmodified storage tanks and 5 gas stations.
7000 multi ton oil and gas will be reused
oil and gas pollutants is a volatile gas, sniff the nose, it is invisible. So, how can we get these volatile oil back? The reporter came to a Sinopec gas station on the ten road, standing next to a refueling car, the whole process of refueling, almost no smell of gasoline. According to the gas station staff, the fuel gun in his hand was reformed. It can control oil and gas, mainly relying on two traps. The reporter noticed that there was a steel sleeve at the front of the fuel gun and a rubber sleeve on the outside. Don't belittle this unattractive fuel gun. It costs about 10 thousand yuan.
Liu Yudong, vice director of the management department of Sinopec Ji'nan branch, "the oil and gas recovery system of the gas station contains two parts of one and two oil and gas recovery." Among them, when oil and gas recovery is oil tank truck unloading, gasoline is discharged from tank car into oil tank, pressure of oil tank increases, pressure of tank car is reduced, oil and gas in oil tank is pressed into tank car through back gas pipeline from oil tank under the action of pressure. The two oil and gas recovery is in the process of refueling. Gasoline is added to the tank of the car from the oil tank. At the same time, the oil and gas recovery pump works. Under the action of the air return pump, the oil and gas are sent to the oil tank through the oil gun through the back gas pipeline to achieve the purpose of recovery.
"the reformed gas station hardly smells of gasoline, not only meets the requirements of environmental protection, but also improves the working environment of the front-line staff, and ensures the employees' occupational health." Liu Yudong told reporters.
the staff of the Ji'nan environmental protection bureau gave the reporter an account. The ideal recovery rate of the oil and gas recovery system was 90%. According to this, it was estimated that only 8000 tons of oil and gas, which volatilized every year in Ji'nan, would be recycled and reused in more than 7000 tons.
the recovery facility will be stopped by
the Ji'nan Municipal Environmental Protection Bureau has checked the oil and gas recovery work of each county (city) area, adjusted the work management ledger and examined more than 30 gas stations and 4 storage tanks on the spot. It is found that some owners who have completed the comprehensive management of oil and gas recovery are not in conformity with the standard requirements for the renovation and renovation of the oil and gas recovery units. There are still some problems in individual owners' units that have not been discontinued or used unauthorized use of oil and gas recovery facilities according to the requirements, and 27 gas stations have been dismantled, removed or operated by the city. The notice of suspension of business has been issued because of the difficulty in implementing the transformation.
in accordance with the regulations on the prevention and control of air pollution in the city of Ji'nan, the facilities and places where oil and gas storage tanks, gas stations and tankers have not installed oil and gas recovery units in accordance with the relevant regulations of the state and province, are ordered to stop using the oil and gas units and to be fixed at a time limit, and can be fined under 10 thousand yuan and more than 50 thousand yuan.
the plan for the comprehensive treatment of oil and gas recovery in Ji'nan is also clearly stipulated in the oil and gas recovery work: the installation of oil and gas recovery facilities is not installed on the new, modified (expansion) station and the oil and gas recovery facilities are not installed according to the requirements, and the approval certificate for the operation of finished oil will not be issued. Since July 1st this year, no oil and gas recovery equipment for existing gas stations is not installed, and the approval certificate for the operation of finished oil will not be issued at the annual qualification examination.
