greetings friends

 

I have a question... I am designing a Pressure Vacuum Relief Valve (PVRV) for a tank, the tank will handle two phases of liquid, a flammable condensate and water . 40% water and 60% condensate. The pressure vacuum valve set point must be based on the flammable condensate  only without considering the water ? 

 

Thanks for your answers...

 

I 'm designing the system specifically a tank vent valve vacuum , but the tank will handle a mixture of condensate and water . 40% 60% condensed water. The pressure valve adjustment must be based on the condensed water only without considering ?

The valve vacuum set point should base on the tank Minimum Allowable Working Pressure.

vanecnr,

 

Supposing you are describing an atmospheric storage tank...then:

 

The pressure set point of the PVRV should be within local gauge pressure and MAWP and the vacuum set point within local gauge pressure and MAWV of the relevant storage tank...

thank you fallah

 

Yes the tank is atmospheric... so it doesn´t have to do anything with de fluid storage...? It depends of the operation pressure and the MAWP....

@ vanecnr

 

The PVRV set is based on the design pressure (or MAWP) of the tank. The design pressure inturn is based on the operating pressure of the fluid stored in the tank.
