Good day, 

 

Regarding Tank Blanketing systems, API 2000 provides a method which is for sizing purposes only. 

 

Can someone provide a method to determine the actual gas consumption during thermal inbreathing? Or some formula for thermal inbreathing so I can know the field parameters to measure? 

 

Thank you very much. 

 

Best regards,

Rakesh,

 

There is no generalized method/formula to determine the actual gas consumption for tank blanketing system. All are estimations based on tanks operating conditions...

Thanks Mr. Fallah. 

 

I understand the estimations are based on the tank operating conditions. 

 

On page 42 of API 2000 (6th Edition), there are three formulas which determine the volumetric rate of change due to thermal effects. The equations are all functions of temperature change. 

 

How would you expect these equations to hold for tropical countries where the temperature swing is very small as compared to temperate countries?

Rakesh,

 

For tropical countries the volumetric rate of change due to ambient temperature change would be minimal and mostly be affected by internal liquid temperature change, if there would be.

Thanks once again Mr. Fallah!!

Can we use the same methodology for breaking a vacuum in a flare header after a large hot flare relief?

I had a question concerning zone selection in hazardous area classification:

 

in a plant, i it possible to have a a zone 0 directly covered by zone 2?

A better formulation here would be:  is a jump among zones is allowed?   that means for example having a zone 2 adjacent to zone 0?,   or a non-hazardous area directly adjacent to zone 1? 

 

Thanks in advance
