Controlling flare emissions.

Xodus Group experts review flaring systems and identify BATs for all BG assets globally.

Xodus Group was asked by BG International to develop a Best Available Technique (BAT) toolkit that will help the review of existing and future operations and identify ways that emissions can be controlled and minimised. The toolkit was to cover all BG Group operated assets where flaring occurs or potentially could occur in locations such as the UK, Bolivia, India, Trinidad, Karachaganak, Miskar and Australia.

Assignment scope
We carried out an in-depth industry-wide study of current and future technologies and techniques for minimising and controlling flare emissions, including:

  • Operating controls to reduce flare gas disposal
  • Maintenance
  • Metering
  • Flare-tip design
  • Pilot and purge aspects
  • Flare gas recovery.

All asset types were considered, such as:

  • Sweet / sour gas production
  • Normally unattended installations
  • Coal bed methane
  • Gas reception
  • Onshore sour gas treatment facilities
  • Liquefied Natural Gas (LNG) and re-gasification plants.

Flare systems are an essential safety feature. To ensure safety and asset integrity is maintained and, where possible, enhanced, our Technical Safety & Risk consultants were involved in every phase of the project. Xodus completed a review of the international legislation and corporate standards governing BG flaring activities to assist operations personnel in understanding the relationship between national regulations and BG Group Standards.


  • BAT toolkit provides a rapid and effective method to assess the range of options available to each type of asset and its specific operating conditions
  • The toolkit supports BG’s drive for emissions reductions and energy efficiency
  • The approach can be applied to areas of environmental engineering studies such as power generation and produced water
  • The toolkit supports BG’s Health, Safety, Security & Environment (HSSE) values and value assurance framework which ensures initiatives are effectively applied across the asset lifecycle.
