FLARE AND VENT LOSS MANAGEMENT
Ultrasonic measurement devices used for flare and vent loss management, can detect the high frequency sound that is typical of leaking valves. Applying this detection technique to all flare-connected equipment, which is typically less than 1% of the total number of fugitive emission sources, provides a full picture of the leaking flare system. Quantifying the amount of product lost in each of these leaking internal valves is essential to identify the biggest leaks. Repairing this small number of large leaks without delay results in an important return on investment, typically within a year.
In the past, refineries and petrochemical plants used flare systems to minimize major hydrocarbon releases. Great results were achieved. Additionally, daily continuous small releases to the flare or vent should also get the right attention.
Hydrocarbon losses to a flare system, from varied sources such as pressure relief valves, ball valves, gate- and control valves, represent both an economic loss and a source of emissions. As small flare gas flows cannot easily be measured, most plants are unaware of how much product is lost during normal operating conditions. These uncontrolled product emissions burnt via the flare typically represent an important product loss. As an alternative to installing expensive flare-gas recovery units, an effective flare loss management program can deliver substantial improvements.
