Amine Containing Polymers as Corrosion Inhibitors

在石油和天然气工业中，提取设备的腐蚀是一个代价高昂的问题。 如果腐蚀能够得到缓解，石油和天然气行业的经济机会将得到改善。 众所周知，金属固定装置上的涂层可以帮助解决腐蚀问题，腐蚀问题通常是由改变钻井环境pH值的微生物大量繁殖引起的。 目前的工业解决方案依赖于使用表面活性剂来保护金属设备。然而，一个更有吸引力和潜在的环境友好的解决方案将具有粘附到金属设备上的抗菌涂层。 理想情况下，这些涂层将作为井环境和设备之间的屏障。 为了具有坚固的涂层，优选的材料将具有可以粘附到金属表面的功能。 此外，涂层应具有抗微生物特性。 对于此类应用，具有胺或季铵中心的聚合物或涂层对于抗微生物活性以及粘附到存在于金属氧化物表面上的固有负电荷两者都是理想的。 Schafer实验室的最新进展导致了制备含胺聚合物和涂料的新方法。 具体地，以使用金属钽为特征的新催化剂体系可以介导含胺结构单元的有效合成，所述含胺结构单元然后可以经历进一步的催化以制备聚合物。 所得的聚合物代表了一类新的材料，具有可控的胺或季铵中心的掺入。 因此，这些新材料有望成为潜在的新型防腐涂层。 该项目将探索各种衍生物的合成及其作为石油和天然气开采行业潜在缓蚀剂的开发。在该项目中，将制备一系列新材料并将其运往壳牌进行防腐测试。 每个月都会运送样品，UBC和壳牌的实验团队之间正在进行的讨论将合作设计新材料，以便在项目期间根据防腐蚀测试的性能目标进行测试。 成功识别首选材料将导致以kg规模经济地制备材料的努力。

Corrosion of extraction equipment in the oil and gas industry is a costly problem. Improved economic opportunities within the oil and gas industry are accessible if corrosion can be mitigated. It is known that coatings on the metal fixtures can help to address corrosion problems, which often result from microbial blooms that alter the pH of the drilling environment. Present industrial solutions rely upon the use of surfactants to protect metal equipment. However, a more attractive and potentially environmentally friendly solution would feature anti-microbial coatings that are adhered to the metal equipment. Ideally these coatings would act as a barrier between the well enviroment and the equipment. In order to have robust coatings, the prefered materials would feature functionality that can adhere to the metal surface. Furthermore, the coating should posess anti-microbial properties. For such applications, polymers or coatings that posess amines or quaternary ammonium centers are ideal for both anti-microbial activity as well as adhering to the inherent negative charge that is present on the metal oxide surface. Recent advances in the Schafer laboratory have resulted in new ways of making amine containing polymers and coatings. Specifically a new catalyst system that features the use of the metal tantalum can mediate the efficient synthesis of amine containing building blocks that can then undergo further catalysis to make a polymer. The resultant polymers represent a new class of materials with controlled incorporation of amines or quaternary ammonium centers. As such, these new materials hold promise as potential new coatings for corrosion inhibition. This proposal will be exploring the synthesis of various derivatives and their exploration as potential corrosion inhibitors for the oil and gas exploration industry.In this project a series of new materials will be prepared and shipped to Shell for anti-corrosion testing. Samples will be shipped each month and on-going discussions between the experimental teams at UBC and Shell will collaboratively design new materials to be tested against performance objectives in anti-corrosion testing for the duration of the project. Successful identification of prefered materials will result in efforts to economically prepare the material on kg scale.
