What improvements are needed to convert a fuel oil tank into one for storing diesel? Or what preliminary preparations should be made?:handshake
There are many types of fuel oils, including heavy oil (such as thousand-second oil, 180, 250, etc.) and marine diesel fuel (DMC). If one wants to improve the quality of diesel oil (-10#, 0#), it is essential to clean the tank first. For heavy oil, it is recommended to carry out steam fumigation after cleaning the tank, followed by another cleaning process (especially for heavy oil) in order to ensure the quality of the oil. Generally, fuel oil tanks are equipped with heaters, while diesel tanks usually do not require heating. You can decide whether to continue using the heater based on the actual situation. If it is not to be used, it is recommended to close the inlet valve of the heater and seal it with a blind flange to prevent water from entering the heater.
I think it’s difficult for a simple steaming tank to meet the standards for storing qualified diesel, as some of the heavy oil sticks to the tank walls and ceiling, and steam isn’t effective enough to clean it thoroughly. It’s best to carry out sandblasting treatment after cleaning the tank; this is exactly what we did when converting crude oil tanks to use for gasoline or diesel
Well, the person on the 3rd floor said something very good. I forgot to mention it earlier – it’s best to carry out sandblasting treatment if possible
Hello, friend on the second floor! :handshake What kind of modifications are still needed for the equipment attached to the oil tank?
Heavy oil has high viscosity, making the use of steam time-consuming and inefficient, with unsatisfactory results. It is best to wait until the maintenance period arrives, as this allows for tank cleaning and maintenance, as well as the necessary modifications to switch to diesel. Killing two birds with one stone! :Lol, if you’re in the central or northern part of the country, it’s better to keep the heater on; a slight amount of steam can be used for treatment. Not well expressed; for reference only!
Regular diesel is relatively easy to work with; however, -20 grade light diesel presents difficulties, as there will be issues with the spacing
1. Fuel oil tanks are generally equipped with vents or air outlets on their tops to balance the pressure inside and outside the tank. If they are to be used for storing diesel instead, these vents should be replaced with breather valves. Additionally, to prevent malfunctions of the breather valves, a hydraulic safety valve can be installed, or another breather valve can be added. II. Fuel oil generally does not come equipped with an automatic dehydrator, but diesel does, right?
Heavy oil tanks are usually dome-shaped tanks, with the oil inlet located partly on the top of the tank and partly at its bottom； Diesel tanks come in arch-type, external floating roof, and internal floating roof types, and diesel is further divided into heavy diesel and light diesel. The specific type of oil tank that should be used depends on the purpose, taking into account the specifications for various oil tanks ； Of course, steps such as tank cleaning, tank steaming, gas detection, hot work modifications, and acceptance are also necessary.
If it is changed to a gasoline tank, considerations must be given to fire-fighting facilities. The flash point of fuel oil is around 100, while that of gasoline is only around 20. Also, does anyone have any modified construction plans? Please share them
