Hydrate Corrosion Interaction with Carbon Steel

Historically, flow assurance problems have been dealt with in isolation, where solutions are constructed for each individual problem without considering interactions between, for example, hydrate formation and corrosion. This is known to be a limitation as, for example, corrosion inhibitors share many common characteristics with hydrate anti-agglomerants – both are typically strong surfactants. As part of this research project, and in collaboration with the Curtin Corrosion Centre, we are investigating hydrate deposition on the walls of corrosion resistant alloy and carbon steel. Further work is being done to quantify the effect of carbon steel corrosion on this deposition force, and to identify shear stress limits for deposition.
