The velocity and concentration effect on a pilot scale erosion-corrosion slurry line

摘要

Erosion-corrosion is the primary concern in slurry and oil sand transportation in long pipelines. Extensive research has been conducted on slurry flow erosion-corrosion on the influences of various parameters and the mechanism. However difficulties have arisen concerning the impacts of flow, its control and mitigation in actual slurry pipelines. This is a potential problem not only from the obvious concern of failure following severe attack but also from the localized deep pits, increased pressure drops that may results from the surface roughness. In present work we investigate erosion, corrosion and its synergistic effect on a pilot scale slurry flow pipeline by electrochemical, microscopic analysis and particle trajectory.
