This PhD will investigate and optimise sustainable chemical inhibitors for the corrosion protection of geothermal energy infrastructure, in collaboration with Roemex. A multi-electrode flow cell, integrated with electrochemical sensing, will be designed and utilised to characterise existing inhibitor performance with a view to understand how to develop novel environmentally friendly corrosion inhibitors synthesised from industrial waste products, such as amino acids. The cell will then be used in conjunction with newly synthesised chemistries to optimise chemical blends for corrosion protection of carbon steel in specific geothermal systems worldwide. The materials utilised in the infrastructure of geothermal energy environments are exposed to demanding conditions, such as high temperature and low pH. This creates significant corrosion challenges, which are often mitigated by the application of corrosion inhibitors that adsorb onto the metal surface and establish a protective film. However, many chemical inhibitors possess toxic and unsustainable characteristics so are unsuitable for geothermal energy application, with the goal being to phase-out these chemistries. By adopting a circular economy approach and synthesising chemical inhibitors from industrial waste products, a more sustainable approach to geothermal energy corrosion mitigation can be achieved.

该博士将与 Roemex 合作，研究和优化可持续化学抑制剂，以保护地热能源基础设施的腐蚀。将设计并利用与电化学传感集成的多电极流通池来表征现有抑制剂的性能，以了解如何开发由工业废物（例如氨基酸）合成的新型环保腐蚀抑制剂。然后，该电池将与新合成的化学物质结合使用，以优化化学混合物，以保护全球特定地热系统中碳钢的腐蚀。地热能环境基础设施中使用的材料暴露在高温和低 pH 等苛刻条件下。这带来了重大的腐蚀挑战，通常可以通过使用吸附在金属表面并形成保护膜的腐蚀抑制剂来缓解。然而，许多化学抑制剂具有有毒和不可持续的特性，因此不适合地热能应用，目标是逐步淘汰这些化学物质。通过采用循环经济方法并从工业废物中合成化学抑制剂，可以实现更可持续的地热能腐蚀缓解方法。
