nitrogen depading with vapor equalization line
nitrogen depading with vapor equalization line
(OP)
I need to know what is vent rate during the liquid tranfer from the tank truck. There would be vapor equalization line between the tank truck and the storage tank during the transfer. I would think that because of this vapor equalization line, there would be no or small vent to the VGO. But I need to know how to calculate it regarless how small it is. Please help me on this. Thanks

If the liquid product is gasoline and there is some moderate aggitation (submerged fill) in the liquid recieving tank, then the vapor growth factor (GF) will be around 1.1 to 1.15. This is a rule of thumb, developed years ago in the gasoline vapor control industry. If the loading is splash loading from the top of the top of the receiving tank, the GF can equal as much as 1.5, so be careful.
Also, if your original question arises out of a concern for the necessity of the a vapor control system, then a vapor control end device will likely be necessary because of breathing vapor losses from the tank from diurnal heating and cooling of the storage tank.
If the vapor pressure of your liquid product is low, then you can ignore everything in this post.
