Refer to API 2000, Annex A.1.2, it is assumed that the maximum operating temperature of the vapour space of the tank is approximately 48.9°C. If the fluid store at 60°C with Nitrogen blanketing (N2 supply temperature at 45°C), Table A.3 in the Annex A is not applicable in this case and the formula from Section 4.3.2.3 shall be used, is that correct? I found that the thermal inbreathing rate from the formula and interpolation from Table A.3 have a significant different value. Kindly advise. Thanks.
