Fuel system and method
First Claim
1. A fuel system comprising a fuel tank, a vent tank fluidically connected to the fuel tank ullage via ventilation pipes, the vent tank having a duct extending from the vent tank and open to the ambient atmosphere at one end and open to the interior of the vent tank at its opposite end, and a catalyst disposed in the duct, wherein the catalyst is adapted to deplete one or more reactive components of gas flowing through the duct by catalytic reaction, and wherein the system is configured to deliver gas from the catalyst in the duct to the ullage, via the ventilation pipes.

Abstract
A fuel system includes a fuel tank, a vent tank fluidically connected to the fuel tank ullage, the vent tank having a duct open to the ambient atmosphere and the interior of the vent tank, and a catalyst disposed in the duct, wherein the catalyst is adapted to deplete one or more reactive components of gas flowing through the duct by catalytic reaction. Also, a method for depleting one or more reactive components of gas in the fuel system, includes depleting one or more reactive components of gas flowing through the duct using the catalyst.
