Best Practice: Flaring; Engineering Design and Construction
Once the tightness test on a new section of network has successfully finished, but before commissioning, the inner air is purged using a vacuum pump, which extracts the air from the new section.
Best Practice: Equipment Leaks; Continual Improvement
Implementing analysis and feedback after third-party damage; improving the accuracy of maps of the network; creating partnerships with relevant stakeholders; raise public awareness of the risk of third-party damage.
Reduction of vented gas from glycol regeneration
Best Practice: Operational Repairs; Equipment Leaks
Flares burn flammable gases that would otherwise be released into the atmosphere. Flaring in upstream oil and gas operations may be needed for safety reasons, because of a lack of capacity to use produced gases, or as a part of routine emission controls.
Tackling methane emissions from fossil fuel operations represents one of the best near-term opportunities for limiting the worse effects of climate change because of its short-lived nature in the atmosphere and the large scope for cost-effective abatement, particularly in the oil and gas sector.
Engineering design can be used to reduce methane emissions prior to the start of operations for new facilities or modifications to existing facilities.
ExxonMobil is progressing a comprehensive methane management pro-gramme which is on track to meet its goal of reducing methane emissions by 15% in 2020, compared to 2016.
