	I beleive we need to have the cone section of the fixed roof above the internal floater in a fixed roof tank to have a blanketing system. The Reid Vapor Pressure of the stored crude is 11.0 psia. This scheme is to ensure that any leaking vapor through the seals is confined to the top section of the tank and excess vapor goes to either the flare or a VRU (Vapor Recovery Unit). Alternatively released vapor may be sent to the atmosphere if it does not pose a safety hazard, i.e. the quantities of release is small. Would this be an adequate safe design? If not please advise what kind of control scheme may be considered for a fixed roof tank with internal floaters.

	Based on the little information provided: Why not hire an expert to evaluate your system He will be able to see whatever it is that you have to deal with. Your consultant can advise on the safety of your design. Guess work, by people who cannot see the tank, don't know where you are, don't know your capabilities, etc. etc. will lead nowhere, fast.

	Yep. Hire someone who can see the project and knows what to do. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	I have a patented system which can ensure that only Nitrogen will go out in worst circumstances. There is a balloon inserted in the tank and also above. These two are connected and you have variable vapor space with zero leakage lifelong! You can google Indian patents number 219430 dated 6/5/2008 with my name Shekhar Kulkarni.It is called vapor formation prevention system. What is the storage liquid?
