Solution: A new provision added to the petrochemical regulations
Thread Content
A new provision has been added to the Petrochemical Regulations (draft for approval): Both 6.4.1(8) and 6.4.3(4) stipulate that for (flammable liquids, liquefied hydrocarbons), “the distance between adjacent crane positions at two loading/unloading stacks on the same railway loading/unloading line should not be less than 24 meters.” I don’t understand what it means. Let’s all discuss this provision together.
I think this is the safety distance that should be maintained between platforms handling the two types of oil; with this distance, two trains can be loaded simultaneously, and there is also a safety distance between the two trains
I’m not quite sure; looking forward to an expert’s answer
When two unloading vehicles operate simultaneously on one side, the distance of 24 meters between the two crane positions ensures a sufficient safety margin between the parking spaces
Each train car is 12.5 meters long; if the length is not at least 24 meters, it is not allowed to unload goods from two adjacent cars at the same time
The explosion and fire hazards of gasoline, kerosene, light diesel and heavy oil, as well as lubricating oils and liquefied hydrocarbons, vary greatly; therefore, the loading and unloading facilities for these substances should be arranged separately. When gasoline, kerosene, light diesel, and heavy oil, along with lubricating oils and liquefied hydrocarbons, are handled using the same loading and unloading line, it is necessary to maintain a certain distance between their storage areas for safety reasons ； The loading and unloading of heavy oil, lubricants, and liquefied hydrocarbons takes a long time, so they are generally located at the back of the operation line. In this way, while the rear is unloading heavy oil or lubricating oil, as well as liquefied hydrocarbons, the front can carry out shunting operations with gasoline, kerosene, and diesel tank cars. Therefore, it is stipulated that the safety distance between adjacent elbow pipes should not be less than 24 meters. (Note) In many oil depots, railway loading and unloading operations are not frequent, and gasoline, kerosene, light diesel and heavy oil, lubricants, and liquefied hydrocarbons are not handled simultaneously; allowing no restrictions on the spacing between transfer pipes can reduce the length of the railway track. Save on investment. Additionally, it should be noted that railway tank cars are 12.1 meters long (the extension for such tank cars is 1.1; the standard length is 11 meters, and 11 * 1.1 = 12.1 meters)
