Insulated Tanks
The shell temperature is assumed to be the same as the liquid temperature
The shell temperature correction factor is determined as follows:
and
Where:
KC = Shell temperature correction factor
TS = Tank shell temperature
TB = Base temperature (temperature at which the tank was strapped)
α = Linear coefficient of expansion of the tank shell material
EXAMPLE CASES
Case 1Strapping table at base temperature of 60 °F, shell is mild steel, non-insulated. Strapping volume is 100,000 bbls, ambient temperature is 70 °F, product temperature is 155 °F. Question: What is the corrected gross volume?
The following are the resulting calculations.
The new corrected volume is determined by this equation.
The situation is the same as in Case 1, but the strapping table at base temperature is 185 F. Question: What is the corrected gross volume?
The following are the resulting calculations.
The new corrected volume is determined by this equation.
