摘要:
An underground storage tank maintenance system includes a system of monitors to determine pressure and humidity in the system. Inert gas may be supplied into the ullage of the tank. The inert gas may first pass through an interstitial space as between the primary storage and secondary containment, and then passed into ullage to capture contaminants on the way out of the vent to atmosphere. The system and method prevent hydrocarbons exiting to atmosphere. Humidity sensors may be set along vent to determine water contamination and trigger drying cycles. Pressure readings help identify system leaks.

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 is controller into coupling to access ullages. Blanket gas is provided upon fueling events to stabilize the pressure m 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.

A dome-based cyclic inert sealing system for an external floating roof tank includes the external floating roof tank, a dome structure, an inert sealing pipeline, and a gas source servo device; wherein the dome structure is formed by a top portion of a tank wall of the external floating roof tank for sealing; the dome structure together with an internal wall of the external floating roof tank, a floating plate and a sealing device form a gas phase space which is isolated from atmosphere, so as to fill the gas phase space with an inert sealing medium; the inert sealing medium is a gas fire-fighting medium used in a suffocation fire-fighting method; the gas source servo device is connected to the gas phase space through the inert sealing pipeline and communicates through a valve for feedback-controlling states of the inert sealing medium in the gas phase space.

摘要:
A plurality of resilient bladders filled with an inert gas line the walls of a fuel tank to protect fuel in the tank from explosion or leakage in the event that the tank is punctured by a ballistic projectile. The thickness of the bladders is controlled by a plurality of cords extending from one side of each bladder to the other. The inert gas is continuously supplied to the bladders so that the gas escaping from a puncture in a bladder prevents fuel from leaking from the tank through the puncture. During normal operation, the gas is vented into the tank to fill the ullage space of the tank with the insert gas. A conduit extends into the tank through the bladder. The walls of the bladder are sealed to each other around the conduit, thereby making it unnecessary to seal the walls of the bladder to the conduit.

A gasoline safety tank system utilizing at least one safety tank, each safety tank comprising a tank body with interchangeable inlet and outlet fittings secured to the tank body. A conduit is connected to the inlet fitting and extending into the tank body adjacent the floor of the tank body and below the level of liquid placed in the tank. A pressurized carbon dioxide bottle is selectively connected to the inlet fitting and adapted to discharge pressurized gas into said safety tank through the conduit so that the gas bubbles up through the liquid in the tank into the top of said tank simultaneously cooling said liquid and pressurizing the liquid in said tank. The carbon dioxide bottle is adapted to be alternatively connected to the outlet fitting to pressurize the liquid and propel the liquid out of said inlet fitting and through the conduit.
