Flammable liquids housed in storage tanks are common in the hydrocarbon industry. Tank fires, while rare, represent a significant threat because of the amount of fuel each tank contains. Storage tank fires are often caused by static electricity from fuel being loaded or unloaded from the tank too quickly or from lightning strikes. In Alberta, lightning strike frequency can average one strike/square kilometer per year in many industrial areas.
Tank fires often occur at the flexible seal between the floating roof and the side of the tank called the rim seal. Spartan’s Det-Tronics X3301 flame detector is chosen for this application because it is extremely false alarm resistant and has the ability to detect a small 1ft x 1ft fire over 200 feet away.
Spartan has many Det-Tronics X3301 flame detectors installed in storage tank applications in Western Canada.
*Dome tanks can also be outfitted with the flange mount for flame detection.
