Pipelines have formed an integral part of our natural gas transportation infrastructure fordecades and their importance is growing, as resources are depleted and demand increases.Contamination in pipelines is a serious issue commercially, for safety, and reliability ofsupply. Early detection of contamination is key and will result in the issue being dealt withbefore it becomes a commercial problem and most importantly an urgent safety issue.Commercially available technology capable of identifying contaminants is expensive, difficultto maintain and calibrate, and slow to operateOur idea is to introduce a novel Raman spectrometer and measurement cell at existing tappingpoints in pipelines in order to rapidly determine the gas composition. This will enablemonitoring of various safety related chemical species, such as O2 or H2S, so that the correctcourse of action can be decided upon before it becomes a serious issue. In addition, otherstandard gas parameters can be monitored, including Wobbe index, which relate to the energycontent of the gas and forms a part of the supply specification.Our goal is to establish a clear “proof of concept” for a novel spectrometry system, includinga novel measurement cell and state of the art Raman spectrometer with unprecedentedsensitivity. The safety, economic and social benefits are numerous and the system would beretro-fitted onto existing pipelines in the global supply network. This technology will bedesigned to be compatible with other novel contamination sensors to make multi-species, lossless measurements for complete characterisation of natural gas in highpressure pipelines.At a time of change in the global energy industry in terms of changing sources of gas andsecurity of energy supply, this innovative technology will provide the UK with a competitiveadvantage in the global energy supply market. Oil and gas multinationals have already showngreat interest in the concept
