Case study: why Gasunie exceeds expectations to reach emission targets

Gasunie in The Netherlands takes emission management seriously. They go the extra mile to reach their environmental targets and to present accurate and trustworthy data of their emissions. Why are they upholding these standards?

“We have been executing traditional Leak Detection And Repair (LDAR) ever since the environmental legislation for gas processing installations was included in the permit” says Ronald Kenter, Environmental Coordinator at Gasunie.

Back in 2007, Gasunie therefore searched a service provider that could help them manage fugitive emissions. “We came across The Sniffers and we have been working closely with them ever since and, most importantly, we have seen great results” Ronald adds.

Setting the bar for fugitive emission reduction

The collaboration between Gasunie and The Sniffers thus far consisted of executing classic LDAR with Flame Ionization Detector (FID) or Photoionization Detector (PID) devices at approximately 27 different locations and reporting these emission figures.

“By having our fugitive emissions measured and reported by a certified third party, we already complied with environmental legislation” says Ronald.

However, Gasunie has set its own emission targets for 2030, adds Henk Brands, Gasunie´s Emission & Compliance Advisor. “These targets are based on those set by the Dutch environmental regulator DCMR. If we want to realize our ambitions, we need to look beyond traditional LDAR and find techniques and technologies to reduce our fugitive emissions even more.”

The need for accurate emission data

We look for accurate emission data. However, multiple techniques, including FID/PID, quantification of the leaks using a High Flow Sampler and screening with IR cameras, are required to report accurate data.

Significant results with classic LDAR

“I believe that quantifying leaks with High Flow Samplers, also known as bagging, is currently the measurement technique that gives the most credible emission figures. That is why we recently added both bagging and screening with IR cameras to our contract with The Sniffers. Besides these different measurement techniques, we are currently also discussing the possibilities of emission management software to capture all emission data in a fast and reliable way.”

“Even though we have now added other measurement techniques, that does not mean we have not reduced fugitive emissions by using classic LDAR. In fact, it is quite the opposite” says Ronald.
