Questions regarding the design specifications for SHT3007 petrochemical storage and transportation tank areas
Thread Content
The value for thermal breathing volume in the design codes for petrochemical storage and transportation tank areas is quite high; I remember reading in a book that this thermal breathing volume is calculated based on a certain temperature difference. Does anyone remember where the calculation for thermal breathing comes from? Thank you.
It should be the change in temperature that causes a change in the temperature of the gas inside the tank; the most extreme case of this would be a sudden downpour on a sunny day.
Thank you. Then, how is the capacity of the nitrogen generator determined in the design? Calculated according to this standard, the utilization rate of the nitrogen generator is not high
A pressurized nitrogen buffer tank can be installed, without the need to require the nitrogen generator to have a capacity sufficient to meet the maximum heat generation rate.
It’s better to refer to the tables provided in the standards~~ In fact, considering the volume of the storage tank, the amount of gas emitted is fairly reliable~~ Should we instead find the highest recorded temperature drop/raise in the area in order to make calculations? Hehe~~
Take a look at the regulations in API 2000
