Our company mixes xylene, toluene, benzene, light aromatics, heavy aromatics, naphtha, C9, C5, MTBE, etc., together before testing them and selling them; the test results show that they meet **the standards. May I ask that after the aforementioned raw materials are mixed together and meet the testing standards, the same approach used by large petrochemical companies to produce gasoline through distillation and catalytic cracking can also ensure that the contents of various raw materials comply with the allowed standards. Both blended gasoline and gasoline obtained through distillation ultimately meet **the allowable values for various components**. Ignoring the differences in oil quality, is there a significant difference between these two methods in terms of their harm to human health? 2. Does national standard gasoline contain substances such as toluene, xylene, ethylbenzene, light aromatics, heavy aromatics, C9, C5, naphtha, and MTBE? 3. My current workplace is about 100 meters away from the oil dispensing point at the oil depot; I have never been to that location. I am an accountant and work in the office, so I am not a frontline employee and therefore do not have protective gear or anything of the kind. Is it very harmful? (Usually, no gasoline smell can be detected.) The blended fuel is transported through pipes from the vehicle to the fuel tanks, and from there it is distributed. The storage capacity per tank is 1,000 tons, (at its maximum). The monthly volume is around 5,000 tons; generally, one type of feed amounts to about 30–40 tons, with occasional amounts of 50–60 tons. The total amount of raw materials used in one batch is approximately 200 tons. May I ask, at a distance of around 100 meters, how harmful would it be to me if light passed through the vents of several oil tanks (to maintain pressure)? Thank you, thank you to everyone
In principle, although the blended gasoline produced by your company meets the required specifications, the quality standards refer to physical properties, and since the fuel is a mixture, passing the testing does not necessarily mean it will perform well in practice. As for the hazards, my estimate is that if the wind direction is not exactly from the downwind side and there are no operations involving overturning the oil tanks, the impact should be minimal; otherwise, there might be an impact.
Reply to 2# yidongshihua: Hello, regarding what you said, \"In my estimation, if the wind direction is not exactly from the downwind side and there is no oil transfer operation in the tank, then the impact should be minimal; otherwise, there might be an impact.\" ” I am currently about 100 meters away from the oil tank; I work as an accountant in an office and usually don’t smell gasoline. May I ask if, in summer, every oil depot takes measures such as cooling down or spraying water? It works like this: usually, a tanker truck goes to the oil tank, and then the material inside the tank is transferred into another tank through pipes; after mixing, it is transported away again using a tanker truck via those same pipes. In addition to evaporation at the inevitable joints where the pipes are connected to the fuel tank, there is also evaporation from the vapor vents, as the fuel tank needs to maintain equal pressure inside and outside. Since there is no direct close contact with the raw materials or front-line workers, these are the two situations in which exposure to oil and gas is possible. You said that it would have an impact if one is in the downwind direction. I’m currently in an office about 100 meters away; if I’m in the downwind direction, would the impact be significant? Our facility is a small private oil depot. The reserve amount is at most 1,000 tons. The monthly flow is only 5,000 tons. With such a quantity, over a range of about 100 meters, would there still be an impact, even in the downwind direction? And if so, how significant would it be? Thank you!
