Abstract
A hydrocarbon tank system environment corrosion inhibitor includes use of inert gas, preferably Nitrogen, to blanket ullage and interstice through the tank system. Blanket gas is provided via controller into coupling to access ullage. Blanket gas is provided upon fueling events to stabilize the pressure in the system and prevent entry of atmospheric air and water (vapor). Blanket gas may be continuously run into the ullage and/or other spaces in tank system. A controlled system allows for monitoring of pressures in the tank, and thereby identifies pressure events and even leaks in system due to unusual events, or general loss of pressure.
