Benefits of Using Oil and Gas Recovery Devices
With the rapid economic growth and the rapid increase of car ownership, China's oil and energy supply is becoming increasingly tight, and its dependence on foreign crude oil imports is increasing. According to statistics, China's crude oil imports have reached 100 million tons per year, second only to the United States. Changes in the international situation will directly affect domestic oil supply, and even lead to a sharp rise in oil prices. In addition, the proposed Fee-to-tax reform may lead to a sharp rise in oil prices.
According to some data, in 2003, 50 million tons of gasoline were consumed in China, and at least 280 million cubic meters of oil and gas were discharged during transportation, transportation and marketing. Each cubic meter of oil and gas contains at least 12 kilograms of gasoline. According to statistics, the economic loss caused by oil and gas volatilization alone in China in 2003 was as high as 1.3 billion yuan [280 million cubic meters * 120 kg / cubic meters * 4000 yuan / ton (unit price of gasoline) = 1.344 billion yuan]; according to incomplete statistics, the economic loss caused by oil and gas volatilization in 2004 was as high as 2 billion yuan. Taking a petrol station with an annual refueling capacity of 6000 tons as an example, the volatilization rate of oil and gas in one year is more than six thousandths, that is, 36 tons of petrol are volatilized in white. According to the current gasoline price of 5000 yuan/ton, the total amount of loss in one year is more than 180,000 yuan. That hasn't taken into account the possible continued rise in oil prices.
In addition, the volatilization of oil and gas results in the decline of oil quality. With the evaporation of neptunium, the initial distillation point of gasoline increases, the vapor pressure decreases, the start-up performance becomes worse and the octane number decreases. According to relevant information, when the loss rate of aviation gasoline reaches 1.2%, the initial distillation point increases by 3 C, the vapor pressure decreases by 20%, and the octane number decreases by 0.5 units.
In the process of unloading and refueling of oil stations, a large amount of oil and gas emissions will be generated. The main components of oil and gas are butane, pentane, benzene, xylene, ethylbenzene and so on. Most of them are carcinogens. The average concentration of oil and gas is 10-35 Vol. The harm of oil and gas to human body can not be neglected. After oil and gas are irradiated by ultraviolet light, a series of photochemistry reactions will take place with other gases in the air to form more toxic pollutants, which is very harmful to the health of operators in the gas station and also affects the health of customers entering the gas station. At the same time, the atmospheric environment around the oil station is seriously polluted, especially in downtown areas. In Beijing, all gas stations in the city have been required to install oil and gas recovery systems to meet the requirements of Beijing 2008 Green Olympics.
The problem of oil and gas pollution in foreign gas stations has been basically solved as early as the 1980s, mainly using closed unloading and oil system, oil and gas combustion treatment system or oil and gas recovery system. At present, domestic gas stations generally use open unloading and refueling, and the spilled oil and gas are directly discharged into the atmosphere, causing serious air pollution near the gas stations.
