Emissions survey eliminates 15kt CO2e
Proactive leak detection surveys, supported by targeted maintenance steps, eliminated environmental harm and enhanced operational efficiency.
Score completed an emissions survey at an onshore LNG facility to identify through-valve leakages contributing to the sites total emissions volume. The systematic approach and advanced tools, including the MIDAS® Meter, proved instrumental in identifying a 10” 600# normally closed valve as the main source of significant leakage, despite the complexity of the process system and the substantial number of potential leak sources.
The initial survey results were validated through traditional Pressure Build-Up (PBU) testing procedures and a Differential Absorption LIDAR (DIAL) survey, confirming the severity of the through-valve leakage. Based on these conclusive results, the client decided to isolate the faulty valve completely.
Impact
By isolating the valve, 15 kt of CO2 equivalent emissions (per annum) were eliminated, resulting in a production saving of USD 800 thousand.
By utilising advanced leak detection and quantification technologies within a systematic approach, the source of emissions was quickly, non-invasively, and positively identified and eliminated, showcasing a commitment to sustainability and operational excellence.
- Stacks emitted 0.5 tonnes of CO2 per day
- 89 valves were surveyed and an emissions leak was identified
- Score implemented a solution which eliminated 15kt CO2 emissions annually
- Saving the client $1m USD annually
D2Zero is at the forefront of the energy transition. We are meeting the dual challenge of decarbonising traditional energy sources, whilst accelerating the transition to renewable energy.
