How to determine the annual turnover volume of an oil depot
Thread Content
There is an existing commercial oil depot with a capacity of 68,000 cubic meters, used for storing oils and chemicals such as gasoline, diesel, heavy oil, toluene, xylene, and methanol. I would like to know how to determine the annual turnover volume of these various materials in this depot I know the turnover coefficient method: Vs=G/(K*ρ*η), which can be used to calculate the annual turnover value of 2G, but I’m not sure how to determine the turnover coefficient K Another method is the days of storage approach: Vs = (G*N)/(ρ*η*τ), which allows for the calculation of the annual turnover rate G. But how are the number of days of oil storage N and the number of days oil is in use per year τ determined?
The turnover coefficient is equal to the annual turnover amount of the oil divided by the capacity of the oil storage equipment. The turnover coefficient for level I and II oil depots is generally set between 1 and 3, while for level III and above it ranges from 4 to 8.
The number of days for oil handling shall be determined based on actual conditions! 350 is generally used. Remember, don’t pay any attention to my numbers – they’re just approximate! You need to base it on your actual situation
I don’t know how to determine the turnover coefficient K? There seems to be no clear formula for this coefficient, but it is usually capacity × safety factor × average density; within Sinopec, this coefficient is set at 0.67. How are the number of days oil is stored (N) and the number of days oil is in use per year (τ) determined? There are also relevant regulations for this; it’s not a unified standard. I’m on a business trip this week, and the documents are on the office computer. I’ll look up the relevant information next Monday and get back to you then.
How are the oil storage days N and the annual operating days τ of the oil determined? There are relevant regulations on this in SHT3007-2007; you can download it by yourself, or you can leave your email address on Monday and I can send it to you for your reference only.
I also study oil and gas storage and transportation; I hope to make a friend so that we can help each other in the future. :handshake
Regarding the determination of turnover coefficients and storage capacity, standards and formulas are important, but what’s most crucial is exchanging opinions with the owner and reaching a decision through discussion. Those formulas are just auxiliary tools.
The turnover volume of a oil depot refers to the amount of gasoline loaded at that depot in one year. This is the definition from the \"Emission Standards for Air Pollutants in the Petroleum and Refined Oil Storage, Transportation, and Sales Industry\" (draft for comment).
Do not mislead beginners on the 8th floor; it does not refer solely to gasoline. As for the annual gasoline loading volume at the oil depot you mentioned, it is a specific statistic under that standard, and it cannot be simply applied to the original question.
Generally, the option with the lowest cost and lowest management fees is considered first; of course, factors such as commercial oil depots, military oil depots, and the size of the oil depot also need to be taken into account.
