A novel contamination sensor to make multispecies, multi-drop, lossless measurements for complete characterisation of natural gas in high pressure pipelines - LineGas

几十年来，管道一直是我国天然气运输基础设施不可或缺的一部分，随着资源的枯竭和需求的增加，管道的重要性越来越大。管道中的污染是一个严重的商业问题，对于供应的安全性和可靠性来说。及早发现污染是关键，这将导致问题在成为商业问题之前得到处理，最重要的是成为紧急的安全问题。商业上能够识别污染物的技术昂贵，难以维护和校准，并且运行缓慢。我们的想法是在管道中现有的分流点引入一种新型的拉曼光谱仪和测量单元，以快速确定气体成分。这将使得能够监测各种与安全有关的化学物种，如O2或H2S，以便在它成为严重问题之前决定正确的行动方针。此外，还可以监测其他标准气体参数，包括沃贝指数，它与气体的能量含量有关，是供应规范的一部分。我们的目标是为新的光谱系统建立一个明确的“概念证明”，包括一个新的测量单元和具有前所未有的灵敏度的最先进的拉曼光谱仪。安全、经济和社会效益众多，该系统将安装在全球供应网络的现有管道上。这项技术将与其他新型污染传感器兼容，为高压管道中的天然气进行多物种、无损测量。在全球能源行业不断变化的天然气来源和能源供应安全方面发生变化的时候，这项创新技术将为英国在全球能源供应市场提供竞争优势。石油和天然气跨国公司已经对这一概念表现出极大的兴趣

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
