How deep should the large tank feed pipe be inserted?
Thread Content
For large oil tanks, such as hydrogenation tail oil and pyrolysis gasoline, if the feed pipe is 12’, and the tank capacities are 10,000 cubic feet, 5,000 cubic feet, 3,000 cubic feet, and 2,000 cubic feet, then how deep should the feed pipe be inserted into the tank? What principle is used to determine this depth? Is there a regulatory basis? Thank you!
The length of the insertion tube should not be less than the diameter of the pipe, generally 500–1000 mm.
The top of the insertion tube should be designed with a downward slope, and holes should be made on both sides of the tube in order to reduce the impact of the feed material on the liquid level, floating disk, and storage tank. There are no specific regulations regarding the insertion length, but in many cases it extends roughly to the middle of the tank
The person upstairs said it needs to be extended to the middle of the tank? If it’s a tank with a capacity of 10,000 cubic meters, then 15 meters would be needed to extend it to the middle – haha, that seems a bit too deep, doesn’t it? I haven’t seen any relevant guidelines, so I wonder whether when people deal with issues in this area, there is a greater degree of subjectivity involved
Hehe, if it’s too long, just remove some of it. But if the length is increased, more oil will separate on the sides of the tube, and by the time it reaches the end, the flow rate will be lower, so the impact will be less. A length of over 10 meters seems acceptable; we already have ones like that
What the original poster needs to know is the insertion depth, not the insertion location (it sounds a bit awkward when put that way, haha). Those who are above can tell the original poster the insertion depth of the feed lines in their storage tanks for his reference
A tank with a capacity of 10,000 cubic meters doesn’t have feeding at the top; material enters through the side walls, at the bottom of the tank
