In this presentation, multidimensional GC configurations will be discussed for different petrochemical analyses. This will include classical heart-cut two-dimensional GC (2D-GC), whereby selected fractions from a high resolution first dimension separation are transferred to a high resolution second dimension separation, as well as comprehensive GC (GCxGC), whereby the entire sample is separated on a high resolution first dimension and a fast (low resolution) second dimension. The complementar...

The detection and quantification of fugitive and diffuse methane emissions has become an increasing priority in recent years. As the requirements for routine measurement to support industry initiatives increase there is a growing requirement to assess and validate the performance of fugitive emission measurement technologies. For reported emissions traceability and comparability of measurements is important. This talk will present recent work on addressing these needs.  Differential Absor...

We present a case study of a validation experiment to characterise the precision and uncertainty constraints of a newly developed mass balancing flux calculation method, using in situ measurements of methane concentration sampled by an unmanned aerial vehicle (UAV) platform.  This case study (funded by the UK Environment Agency) was conducted by the University of Manchester and National Physical Laboratory with assistance from the UK Met Office at its Cardington research facility. The aim...

With the ongoing integration of biogas and other biofuels into existing energy infrastructure, there is a focus on the need to establish rigorous technical specifications for biogas and biomethane. Such regulatory framework requires the determination of the biogenic content of gases consisting of both biogenic and natural gas. One potential tool for making this determination is stable isotope analysis. The isotopic composition of natural gas and biogas varies significantly, with the isotopic...

National Grid Plc is incentivised by the Office of Gas and Electricity Markets (Ofgem) to conduct research into new techniques to enable National Grid Gas (NGG) to improve understanding and transparency, and allow for cost-effective mitigation, of greenhouse gas (GHG) venting on the National Transmission System (NTS). The mechanism by which this is done is special condition 8J of the Gas Transporters Licence, the Greenhouse Gas Investigation Mechanism (GHGIM). Since 2008 NGG has conducted...

In June 2016, GHGSat launched the world's first and only satellite capable of measuring greenhouse gas emissions (CO2 and methane) from targeted industrial facilities around the world. The objective of this paper is to report on the early results in using our patented technology to accurately and quickly detect methane leaks around oil and gas installations which are costly, dangerous and have an environmental impact.  The technology on our satellite was designed to be capable of detectin...
