I have a few questions regarding the storage of residue oil
Thread Content
I recently came across a project related to the storage of residue oil. Since this is my first time dealing with such a design and I have no experience in this area, I would like to ask a question: The project involves one dome tank with a capacity of 5000 m3 for storing crude oil, and now this tank is being used to store residue oil. Since residue oil generally has high viscosity, poor flowability, and poor heat transfer properties, it is necessary to install internal heating devices in the tank during storage. However, since only a few sets of heaters can be placed at certain heights at the bottom of the tank, how can heat transfer within the residue oil tank be ensured, so that the temperature of the oil near the heaters rises rapidly while there is little temperature increase in other areas? Are any forced convection measures required?
In this case, a loop might be necessary; the original poster can go and ask in the logistics section, as it’s more professional there.
Thank you for the reminder. I searched the forum before posting, and saw that there are many discussions on residue in the petrochemical section, so I posted it here first. You mean direct heating by a heater, with the pump activated to force circulation, right?
Well, our heavy oil tanks all have circulation lines, powered by mechanical pumps.
What is the viscosity of your heavy oil, generally?
The densities of the heaviest slag and slurry are around 1.0–1.1.
No need; the heating coils are located at a distance of around 40 to 80 centimeters from the bottom, and depending on the design height of the outlet, the heated oil will rise upward due to convection
