Hello All,

 

Hope you are in good health and keeping safe.

 

I am looking forward to calculating vapor loss per year from a methanol [Above ground] storage tank designed as per API 650 with a 3 Inch open to atmosphere Breather Valve installed on top of the tank nozzle.

 

It'll be great if someone could guide how to estimate standing and working losses and share excel sheet to perform calculation for the same. I have following data available and looking to get the result.

 

Data Available:

• Diameter: 3000 mm
• Height: 4500 mm
• Design Pressure: 0.18 KG/CM2(G) + FOL
• Design Temp: 47 Deg C
• Operating Pressure: ATM
• Operating Temp: AMB
• Breather Valve pressure setting: 0.1 kg/cm2 (g) & vacuum setting at -0.004 kg/cm2 (g).
• Service Medium: Methanol
• Average Temp of Location: 45 Degree C

Thanks & Regards!
