SUSPECTED THERMAL LEAK IN THE BUTANE TANK (DOUBLE WALL TANK)
SUSPECTED THERMAL LEAK IN THE BUTANE TANK (DOUBLE WALL TANK)
(OP)
Good morning everybody,
We have in our industrial plant a butane double wall storage tank with technical data as fellow:
- Volume of tank is 70.000 m3.
- The operating temperature is –40°C.
- Inner tank is made of steel and outer tank is made of concrete.
- The tank is in operation phase.
At this time, we suspect a thermal temperature leak according to the indications of the temperature probes installed in the wall of the tank.
Please , what could be the possible codes applicable in this case.
Thanks in advance for your assistance.

Same questions apply - what is insulation?, what are temperatures - -40 inside to - 3 in concrete looks Ok to me
What is monitoring of the annulus - pressure? - Gas detector?
Do you mean cause or code? - Code will be written in your design data.

Thank you for your reply,
In response to your message, please find below my clarifications:
1) Insulation: PERLITE
2) temperature is inside the tank: -5°C
3) in annulus space we monitor the leak detection by thermal sensors.
My question is: Can I use BS 7777 std for this monitoring?
Thanks in advance,

I can't work out how the temperature "inside the tank" is only minus 5 if you're storing liquid butane at very low pressures - it was minus 40 in the post above....
please explain and provide a proper cross section of this tank so we can understand what it is made of, where the temperature sensors are and why you think there is a leak.
Or are you talking about a "cold spot" where the perlite insulation isn't as good??
The question is vague and confusing so that's the answer you get.
