What is the loading and unloading time for oil products?
Thread Content
Generally speaking, how much time is required to load and unload oil using a flexible hose? An approximate number will do.
Original poster, are you installing or removing something? What kind of materials are used, and what size are the flexible hoses? With such questions, no one will be able to answer you.
For petroleum products such as gasoline, diesel, lubricating oils, etc., let’s discuss loading first.
The original poster’s question is not professional at all; you should clarify whether it’s a train or a tank car that’s being used, what the loading capacity of the vehicle is, the size of the transfer hoses, as well as the flow rate and head pressure of the pump, among other things
These days, a volumetric loading device is generally used to control the loading speed; for pipes with a diameter of 80, the flow rate is usually controlled at 600–800 liters per minute, and you can calculate based on this rate. A regular tank truck takes about ten to fifteen minutes.
The original poster’s question is unclear, making it impossible to answer. Variety, tank cars, pumps, flow rate, diameter of transfer pipes, etc. :o
Of course, the pump, pipe diameter, etc., are determined based on standard values; if I have all that information, I can calculate it myself. It’s mainly experience points. Loading refers to cars.
When loading general oil products, for safety reasons, the flow rate is kept at no more than 4.5 m/s. Different oil flow rates are considered differently; some sources state that the maximum value is 7 m/s. The diameter of the loading nozzles used for loading oil in tank trucks is usually 80 mm. Using these values, it is possible to estimate the loading rate per hour. The loading time is also related to the volume of the tank truck being used.
The initial flow rate should not exceed 1 meter/s; once the oil covers the outlet of the dip pipe, the flow rate can be increased gradually. But it shall not exceed 4.5 m/s at most. Additionally, the safe flow velocity for different pipe diameters and different oil types is also taken into consideration. There are specific calculation formulas. Search for it online. I forgot now.
Depending on the size of the flexible hose, smaller hoses have a diameter of DN80/DN100, while larger hoses have a diameter of DN300/DN250. It takes a few minutes to fill one tank truck, but an oil and gas recovery system is required
This is mainly related to the allowable flow rate; generally, the maximum flow rate is 4.5 m/s. For a DN100 dip pipe, the corresponding maximum loading rate is around 125 m3/h. Railway tank cars have a capacity of around 60 m3, so the loading and unloading time is about 30 minutes. Road tank cars have a capacity of over 8 m3; assuming a capacity of 8 m3, the loading and unloading time is approximately 4 minutes
Just ask the loading operator and you’ll easily find out; it’s all too academic when you think about it.
It depends on the capacity of the tank truck; it usually takes a few minutes to about ten minutes.
Sometimes it is also related to the requirements set by the railway authorities; for example, the standards generally specify a loading time of 1.5 hours, but since we don’t have our own trains for this purpose, the railway authorities allocate us only one hour for loading, and we have no choice but to comply with that timeframe!
