Hydrocarbon Storage Leak Detection: Gasoline, Jet Fuel, Diesel, and Oil Tanks

Hydrocarbon Storage Leak Detection

Leaks in hydrocarbon storage tanks may occur via the tank walls or the tank bottom. It is common for an older oil storage tank to have corrosion at its base, emerging from either internal corrodents or external influences such as soil moisture and pH. The addressable sensing cables in the Naftosense hydrocarbon leak detection system offer continuous monitoring and protection for various hydrocarbon storage tanks, aiding in avoiding soil contamination and product loss. The Naftosense hydrocarbon leak detection cable is both fast sensing and reusable. 

The cables' underlying technology uses a physical phenomenon that has been around for decades: employing polymeric absorption to detect the presence of compounds in the vapor phase. Polymer-absorption sensors consist of a chemically sensitive absorbent deposited onto a substrate that acts as an electrode. As chemical vapors contact the absorbent, the chemicals absorb into the polymers, causing them to swell. The electrode's resistance varies as swelling occurs, which may be quantitatively measured and recorded. The swelling is proportional to the chemical vapor concentration in contact with the absorbent. PAS technology, which dates back to the 1950s, has a proven track record of identifying the presence of hydrocarbons. The technology works in harsh environments and provides real-time, cost-effective critical infrastructure integrity monitoring.

Leak Detection for Underground Bulk Storage of Hydrocarbon Products

Leak Detection for Underground Bulk Storage of Hydrocarbon Products

Gasoline, heating oil, and other liquid petroleum products, which make up most of the nation's fuels and energy supply, are frequently held in underground storage tanks or USTs. There are around 553,000 USTs that store petroleum and other hazardous materials in the USA. Leaking can have significant environmental and health consequences, including contamination of groundwater, which is the source of drinking water for over half of the population of the United States.

Corrosion around the base of oil storage tanks is common, resulting in leaks, product loss, and soil pollution. Because early identification of UST system leaks helps stop contamination from spreading from UST locations, the EPA requires UST system owners and operators to detect releases.

All regulated tanks and piping must have release detection, so the discovery of leaks happens fast before contamination spreads from the UST site. An owner must provide their UST system with release detection (often called leak detection). There is no single leak detection technology best for all locations or a single type of leak detection that is consistently the least expensive for USTs. Each method for detecting leaks has its own set of features. 

Secondary Containment with Interstitial Monitoring

Secondary containment separates the tank from the rest of the environment. The leak stays between the tank and the barrier, where the leak gets identified. A leak moves towards the interstitial monitor due to the form of the barrier.

Monitors for the Interstitial Space 

Monitors used for sensing leaks between the tank and the barrier are interstitial monitors. They warn the operator if a leak is detected.  The physical presence of the leaked product, whether liquid or gaseous, is indicated by several detectors. A measuring stick, placed at the lowest point of the confinement to detect pooled liquid product, is an example of a simple monitor. For critical areas where safety and security are an issue, more sophisticated automated systems are available to check for leaks continuously.

Oil leaks in underground pipelines can be challenging to detect, but hydrocarbon leak detection devices from Naftosense provide an excellent solution. They continuously check for hydrocarbons in various situations. Their unique addressable sensing cabling is IP68 rated, meaning it will continue to function in high water levels and still pinpoint the source of oil leaks. 

The Naftosense hydrocarbon leak detection system is perfect for airports and gasoline station storage facilities since it quickly detects and repairs any detected fuel, diesel, or jet fuel leaks. Small-volume hydrocarbon detection in mission-critical applications such as power generator rooms in data centers and other similar locations means you'll be able to detect a leak before any damage occurs, reducing downtime and costs.

Emergency Diesel Generator Fuel Leak Detection

Emergency Diesel Generator Fuel Leak Detection

Emergency generators are often the final line of defense for many facilities when a utility failure or a catastrophic incident occurs. Undetected diesel oil leaking on generators can be exceedingly harmful, with potentially profound effects, especially in data centers, health care facilities, airports, or military facilities. 

Diesel oil leak detection by Naftosense protects diesel generators and the diesel systems that support them, such as storage tanks and diesel distribution pipelines. The leak detection system includes addressable sensing cables, point sensors, and digital leak monitoring panels. 

Once a leak is discovered anywhere along the sensor cable, the digital leak monitoring panels will offer information on the precise position of the leak. The monitoring panel also provides information on the persistence of the leak and the magnitude of the leak. The sensor cable only responds when it comes into contact with hydrocarbons, making it perfect for detecting diesel fuel. 

By installing a hydrocarbon sensing sensor cable in the floor space surrounding the generators and fuel tanks, you can create a system that detects fuel considerably more quickly than any other conventional way. Apart from rapid detection, this technique enables the owner to immediately determine if a leak is a minor nuisance impacting only a few inches of the sensor wire or a significant leak affecting a broad section of the sensor cable. This degree of detail can be incredibly beneficial when the equipment is in a remote location. Upon discovering a leak, immediately action may be taken. Depending on the installation, you may opt to shut down the problem engine, stop the associated fuel pumps, or notify the facility's manager of the condition.

The following are some of the benefits of Naftosense Diesel Leak Detection Systems
  • Water and pollutants do not affect the accuracy of the detection. 
  • Leaks can be detected early and accurately. 
  • Small, medium, and large area monitoring. 
  • The unique address of each sensor cable allows for individual identification of multiple leaks. 
  • Can be deployed in explosive environments. 
  • Installation and expansion are simple, and maintenance is simple.
