Inspecting flaring networks

GAS OR LIQUID LEAKS

In industrial plants, valves and actuators on process, utility and flaring networks can leak over time due to internal wear, malfunction or incorrect calibration.

These line leaks of gas or liquid not only have an impact on process control but they also generate significant product losses. Repairing these leaks is therefore a key issue in terms of Health, Safety and the Environment.
For example, flaring causes emissions of hydrocarbons and greenhouse gases such as CO2 or methane, as well as toxic gases such as H2S.
The petrochemical and refining industries have made enormous progress in terms of reducing their emissions yet controlling these continuous gas flows discharged by flaring represents a new challenge.

Small leak rates from flared gases are difficult for the operator to measure, but over a whole year come to represent significant volumes. The return on investment from these programmes is generally less than a year.

 “As an example, the GGFR (Global Gas Flaring Reduction partnership) initiated by the World Bank used satellite measurements to estimate that 150 billion m³ (cubic metres) of natural gas are released by flaring each year. This equates to 30% of Europe’s annual consumption. Line leaks on flaring network equipment contribute to these emissions.”

Leak detection and anomalies

Bureau Veritas continuously strives to develop innovative solutions to enhance its expertise and deliver even better services to its customers. We created global energy loss reduction programmes, including line leaks and flare inspection.

While we complete these tasks, our experts can also check for errors in drawing updates (pipeline alterations, etc.) and anomalies on site, such as incorrect installation, damaged cage ladders, etc.).
