NITROGEN BUBBLER SYSTEM IN FUEL TANK AND METHOD
First Claim
1. An assembly of fuel tank and bubbler system comprising:
- a fuel tank defining a storage volume adapted to receive fuel therein, the fuel tank comprising at least one fuel inlet, at least one fuel outlet, and at least one gas inlet adapted to be connected to an inert gas source to feed inert gas to fill an ullage in the storage volume; and
a bubbler system having at least one pipe extending into the fuel tank and adapted to be immersed into the fuel of the fuel tank, the pipe having a porous structure, the at least one pipe adapted to be connected to an inert gas source to inject inert gas via the porous structure into the fuel of the fuel tank.

Abstract
An assembly of fuel tank and bubbler system comprises a fuel tank defining a storage volume adapted to receive fuel therein. The fuel tank comprises at least one fuel inlet, at least one fuel outlet, and at least one gas inlet adapted to be connected to an inert gas source to feed inert gas to fill an ullage in the storage volume. A bubbler system has at least one pipe extending into the fuel tank and adapted to be immersed into the fuel of the fuel tank. The pipe has a porous structure. The pipe is adapted to be connected to an inert gas source to inject inert gas via the porous structure into the fuel of the fuel tank. A method for treating fuel in a fuel tank is also provided.

13. A method for treating fuel in a fuel tank comprising:
-
injecting an inert gas in a fuel tank to fill an ullage formed in the fuel tank above a fuel level; injecting an inert gas into the fuel to dissolve nitrogen into the fuel; and blocking gas bubbles in the fuel from an outlet of the tank. - View Dependent Claims (14, 15, 16)
