Engineering a greener future for the natural gas: A modular approach for carbon dioxide rejection at the wellhead and carbon capture for the consumer

拟议中的技术涉及开发既能脱硫天然气又能从工业废水中捕获碳的新型化合物，使用绿色溶剂，如离子液体（ILS）或聚合物溶剂（PS）。如果成功，这些化合物将为捕获石油和天然气工业排放的二氧化碳提供一种廉价而有效的方法。目前去除二氧化碳的方法很昂贵，而且往往只能在有限的情况下应用。例如，使用乙二醇或甲醇系统已被证明可以有效地捕获天然气脱硫中的co2酸性气体，但由于存在氧气和其他污染物，不能有效地用于烟气流。我们建议开发一种新型创新的酸性气体捕获系统，该系统具有双重用途，既可以在海上平台（生产）上有效，也可以在陆上消耗大量天然气（燃烧后）的地方有效。开发一个新系统，整合我们提出的从天然气中去除燃烧前和燃烧后二氧化碳的解决方案，将使新斯科舍省成为碳捕获领域的领导者，并为当地将该技术应用于制造业和化工生产等第二产业提供机会。发展研究力量和基础设施，重点关注二氧化碳的处理和利用，是绿色经济的重要组成部分，也是提高天然气和石油采收率研究的主要推动力。最后，圣玛丽大学成立了海事绿色化学中心（MCGC），以提高绿色化学领域应用研究的意识和影响。我们的倡议将定位新斯科舍省在这一前沿研究的领导者，在国内和国际上。

The proposed technology involves the development ofnovel compounds capable ofBOTH natural gas sweetening and Carbon Capture from industrial waste streams, using green solvents such as ionic liquids (ILS) or polymeric solvents (PS). If successful, these compounds would allow an inexpensive and effective method for the capture of C02 emissions from the oil and gas industries. Current methods for the removal of C02 are expensive and can often only be applied in limited circumstances. For example, use of glycol or methanol systems have been shown to effectively capture C02 acidic gas in natural gas sweetening, but can not be effectively used in flue gas streams due to the presence ofoxygen and other contaminants. We propose to develop a new and innovative acidic gas capture system engineered to serve a dual purpose, being effective on offshore platforms (production) and where large amounts of natural gas are consumed onshore (post-combustion). Developing a new system that integrates our proposed solution for removing carbon dioxide from natural gas, pre-and post-combustion, would make Nova Scotia a leader in carbon capture and also provide opportunities to apply the technology locally to secondary industries such as manufacturing and chemical production. Development of research strengths and infrastructure focused on handling and using C02 is a major component ofthe green economy as well as a major thrust in enhanced gas and oil recovery research Finally, Saint Mary's has formed the Maritimes Center for Green Chemistry (MCGC) to increase the awareness and impact ofapplied research in the area of Green Chemistry. Our initiative will position Nova Scotia among the leaders in this cutting edge research, both nationally and internationally.
