摘要:
A nitrogen blanket system for small fuel tanks is disclosed that includes tank empty-space pressure control for sealed tanks that can hold pressure. The system includes a fuel tank storing some volume of fuel, such as diesel fuel. The remaining empty volume is filled with nitrogen by the disclosed system. The nitrogen blankets the liquid fuel and fills the remaining space in the fuel tank to prevent the accumulation of moisture and thereby prevent corrosion within the fuel tank.
摘要:
A storage tank includes a frame, tank assembly, and scrubber system. The tank assembly including a vessel supported by the frame and having a first end, a second end, and a polygonal sidewall extending from the first end to the second end. The vessel further having a top, a bottom, at least one side, and an internal surface, and an outlet fluidly coupled with the bottom; and a chemical-resistant lining associated with the internal surface of the sidewall and being substantially flexible. A scrubber tank is supported by the frame and fluidly connected to the vessel to receive vapors from the vessel in a way that when a vapor absorption material is disposed in the scrubber tank, the vapors pass into the vapor absorption material.

Articles of manufacture and methods of making and using same concern a container having an internal space and a passivated internal metal surface. The container contains a composition of an acid gas and a balance gas contained within the internal space and in contact with the passivated internal metal surface. The stability of the acid gas concentration over time is enhanced.
摘要:
Methods of passivating a metal surface are described, the methods comprising the steps of exposing the metal surface to a silicon-containing passivation material, evacuating the metal surface, exposing the treated surface to a gas composition, having a concentration of reactive gas that is greater than an intended reactive gas concentration of gas to be transported by the metal surface, evacuating the metal surface to remove substantially all of the gas composition to enable maintenance of an increased shelf-life, low concentration reactive gas at an intended concentration, and exposing the metal surface to the reactive gas at the intended reactive gas concentration. Manufactured products, high stability fluids, and methods of making same are also described.

An underwater storage installation for a cryogenic liquid. A foundation base rests directly on the sea floor. An underwater cell for storing the cryogenics liquid and cryogenic liquid-supply and -discharge conduits. The storage cell comprises a sealed outer chamber and a vapor barrier disposed inside the outer chamber and which defines a watertight space. A separation space is disposed between the outer chamber and the vapor barrier. Spacers are disposed in the space to keep the chamber and the vapor barrier at a distance from one another. The installation can be used for the storage of liquefied natural gas.

A corrosion protection device (nullCPDnull) for inhibiting corrosion of an air compressor collection tank, and relieving the pressure in the tank when excessive condensate accumulates within the tank. A relief passage extends through the plug, and an anode seals the relief passage near the interior volume of the tank. The tank, plug and anode are all coupled in an electrically conductive relationship, and a galvanic circuit is formed when condensate collects near the bottom of the tank. The anode has a lower redox potential than steel, and is preferably made from magnesium. The anode loses electrons with less resistance than the steel tank, so the anode will be consumed through the oxidation process before the steel tank corrodes. Once the anode is consumed so that it no longer seals the relief passage, the condensate and air are discharged from the tank through the relief passage.

Embodiments of disclosure generally relate to corrosion sensors for storage tank applications, using corrosion responsive members and sensors to monitor corrosion in storage tanks, and methods for monitoring corrosion in a storage tank using the corrosion sensors. In one embodiment, a corrosion sensor for a storage tank comprises one or more sensors located on a non-process side of the storage tank and one or more corrosion responsive members located internal to the one or more sensors. The one or more sensors are configured to monitor a change in one or more physical properties of the one or more corrosion responsive members. Data from the corrosion sensor may be monitored locally or transmitted over a network and monitored remotely.
