Cut operating costs and reduce VOC emissions by implementing a leak detection and repair (LDAR) programme.

The primary source of emissions of volatile organic compounds (VOC) from petroleum refineries and chemical manufacturing facilities are leaking equipment, such as valves, pumps, compressors and connectors. VOCs can pose a threat to workers and formulate ground-level ozone, a major component of smog. This secondary pollutant can cause or aggravate respiratory disease, particularly in children. In addition to workers at a facility, the surrounding community can be affected by long-term exposure to toxic air pollutants as a result of leaking equipment.

Leaking VOCs will also contribute to higher running costs due to the loss of expensive products.

SGS LDAR Fugitive Emissions

The US EPA specifies EPA Method 21 to detect VOC leaks from process equipment using portable VOC detection instrumentation. SGS employs over 6,000 environmental, health and safety specialists around the globe, who can help your company design and implement an effective LDAR programme, allowing you to comply with EPA Method 21.

LDAR programmes generally comprise four processes:

  • Identify components to be included in the programme
  • Conduct routine monitoring of identified components
  • Repair any leaking components
  • Report monitoring results

Why choose SGS?

SGS has a physical presence in over 65 countries. Our experienced professionals utilise state-of-the-art technology and software, including FLIR® GF320 infrared cameras and calibrated organic vapour detectors (FID and PID), to thoroughly test all tagged components in compliance with EPA Method 21.

Our specialists can set up a dedicated database or input results into your own databases, helping you rapidly identify, repair and track leaking components. We also use infrared imaging cameras to quickly and easily identify large hydrocarbon gas leaks. These cameras can provide rapid scanning of large areas, delivering real-time thermal images of gas leaks.

When components need repairing, we can check the repairs are adequate and help you instigate a maintenance programme to minimise expensive leaks in the future.
