0423882 Urquidi-Macdonald石油和天然气行业以及环境和运输行业在很大程度上依赖于其管道系统和地下储存容器的完整性。 这些系统在很大程度上受到局部腐蚀的威胁，这可能导致邻近环境的污染，如果管道被定位并被恐怖分子接近，则可能对国家安全构成威胁。 这项研究将用于开发基于低阻抗谱检测地下管道外部腐蚀活动的新技术。 监测地下管道系统和储罐内部腐蚀的技术将与墨西哥研究小组联合开发，其结果将在不久的将来建立一个智能监测系统。 该活动将包括研究生和夏季美国-墨西哥高级研究人员交流计划，通过短期课程和与石油工业运营商的实地活动。 通过联合研究以下领域，将建立一个美国-墨西哥天然气和石油工业传输问题专家小组： (a)回顾和建立了腐蚀机理在模拟环境中的变化 含CO2的原油的冷凝相的条件（. sweet.），H2S（酸性），NaCl和 在管道系统中运输的解离产物： (b)现场电化学测量（直流和交流阻抗），以关联场 为了将实验室结果外推到真实的中， 条件实验; (c)开发一个原型，将评估和表征不同的电化学过程 发生在受内部和外部腐蚀影响的管道中;以及 (d)将模式识别数据挖掘模型收集的数据映射到管道 操作员将遵循以保持系统的完整性。在一个简单的传感器原型中嵌入数据采集和模型的要求将是本研究的产品之一。 长期目标是开发一种经济、准确和易于使用的工具。 该工具将指导管道运营商采取步骤，以保持系统的完整性和健康。 预计两国之间的合作将继续下去，不仅有利于研究生和本科生在这项研究工作中的合作，而且有利于天然气和石油行业运营商的环境和安全。 这项研究工作还将通过建立一个更好、更安全的工作场所，加强两国之间的科学和社区关系。

0423882 Urquidi-Macdonald The oil and gas industry, as well as environmental and transportation industries, rely heavily on the integrity of their pipeline systems and underground storage containers. These systems are largely threatened by localized corrosion, which could lead to contamination of the neighboring environment and, possibly, a threat to national security if the pipelines were located and accessible to terrorists. This research will be used to develop new techniques based on low impedance spectroscopy to detect external corrosion activity in underground pipelines. The techniques to monitor internal corrosion in underground pipeline systems and storage tanks will be developed jointly with a Mexican team of researchers, and the results will lead to building a smart monitoring system in the near future. The activity will include graduate students and a summer US-Mexico exchange program of senior research personnel through short courses and field activities with oil industry operators. A US-Mexican Team of experts on gas and oil industry transmission problems will be developed by means of researching the following areas jointly: (a) Reviewing and establishing the change of corrosion mechanisms in environments simulating conditions of the condensate phase of crude oil containing CO2 (.sweet.), H2S (.sour.), NaCl and dissociation products transported in pipeline systems: (b) In situ (in the field) electrochemistry measurements (DC and AC impedance) to associate the field experiments to the laboratory experiments in order to extrapolate laboratory results in real condition experiments; (c) Developing a prototype that will evaluate and characterize different electrochemical processes occurring in pipelines affected by internal and external corrosion; and (d) Mapping the data collected by a pattern recognition data mining model to the steps that the pipeline operator will follow to maintain the integrity of the system. The requirements for imbedding the data acquisition and model in a simple sensor-prototype will be one of the products of this research. The long-term objective is to develop a tool that will be economical, accurate, and easy to use. This tool will instruct pipeline operators in the steps to follow to maintain the integrity and health of the systems. It is anticipated that the cooperation between the two countries will continue and will benefit not only the graduate and undergraduate students teaming in this research effort, but the environment and safety of the operators in the gas and oil industry. This research effort will also strengthen the scientific and community relations between the two countries by developing a better and safer work place.
