Amine Containing Polymers as Corrosion Inhibitors

在石油和天然气工业中，开采设备的腐蚀是一个代价高昂的问题。如果可以减轻腐蚀，石油和天然气行业将获得更好的经济机会。众所周知，金属固定装置上的涂层可以帮助解决腐蚀问题，这通常是由于微生物繁殖改变了钻井环境的pH值而导致的。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，一种更有吸引力、更环保的解决方案是将抗菌涂层粘附在金属设备上。理想情况下，这些涂层可以作为井环境和设备之间的屏障。为了拥有坚固的涂层，首选的材料将具有能够粘附在金属表面的功能。此外，涂层应具有抗菌性能。对于此类应用，具有胺或季铵中心的聚合物或涂层既具有抗菌活性，又能粘附金属氧化物表面固有的负电荷。舍费尔实验室最近的进展导致了制造含胺聚合物和涂层的新方法。特别是一种新的催化剂系统，其特点是使用金属钽，可以介导含胺构建块的有效合成，然后再进行进一步的催化以制造聚合物。合成的聚合物代表了一类新的材料与控制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料。该提案将探索各种衍生物的合成及其作为石油和天然气勘探行业潜在缓蚀剂的勘探。在这个项目中，一系列新材料将被制备并运往壳牌公司进行防腐测试。样品将每月发货，UBC和壳牌的实验团队将合作设计新材料，在项目期间进行抗腐蚀测试，以达到性能目标。成功识别优选材料将导致努力以经济的方式制备公斤级材料。

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.
