Confirm the calculation of the breathing volume for fixed-roof tanks and floating-roof tanks
Thread Content
This post was last edited by zmwzebra on 2010-3-1 at 23:54. I only know that the breathing rate for fixed-roof tanks is determined with reference to API 2000; so which standard should be used for calculating the breathing rate of floating-roof tanks? In API 2000, it is stated that \"this standard does not apply to external floating roof tanks or free vented internal floating roof tanks\", meaning that API 2000 is not applicable for determining the breathing rate of floating-roof tanks. Then is it API 650 Welded Steel Tanks for Oil Storage? So what are the corresponding national standards? I would appreciate some advice from those who are more experienced.
I’ve encountered this problem too; please have an expert help me solve it
Our usual practice is to determine it based on the volume of your imports and exports; for example, if you export pumps in large quantities
In my opinion, in addition to determining it based on import and export volumes, it is also necessary to take into account the impact of changes in the temperature difference of the gas phase; this factor is also quite significant, I think
I am also looking for standards in this area, but have not found any so far. I came across information on this topic on Google; the keywords I used while searching were internal floating roof tanks, breathing volume, and calculation. It can be checked, but whether it can be used directly in design depends on whether it meets the standards, and this still needs to be studied.
Everyone: Is the calculated breathing volume the actual amount of oil loss? Is it still an oil and gas mixture? Additionally, what are the oil and gas concentrations in fixed-roof and floating-roof tank tops?
For the calculation formulas related to breather valves, Wuhan Jinye Petrochemical Equipment Co., Ltd. can be a good choice; our company is able to provide you with the necessary calculation methods.
The original version says it’s not suitable for external floating roof tanks, right?
