Still about the tank venting capacity.
According to API2000, if the tank is stored above 40ÂșC, out-breathing is increased by evaporation rate.
In my tank, there is hot water emulsion @ around 90C. It is equipped with agitator to maintaine the emulsion stable, N2 blanketing to avoid oxidation, steam coil to keep it warm. Organic product has very high boiling point.
How to determine the evaporation rate in the tank?
Or is it still evaporating? N2 is major component in the vapor phase.
Thanks for any suggestions/advices.
