مقاله Internal corrosion studies in hydrocarbons production pipelines located at Venezuelan Northeastern : تی پی بین

خلاصه مقاله

The demand of fossil energy has boosted the construction of new oil facilities and the preservation of the physical and mechanical integrity of the already existing infrastructure. Corrosion is the main causes of failures in the hydrocarbons industry and half of them are produced by acid gases (CO₂ and H₂S) (Kermany and Harrop, 1996). Within this framework, a monitoring device was developed by PDVSA-Intevep, in order to study the internal corrosion mechanism in a real hydrocarbons production system. The results show the advantages offered by this tool, which allowed studying thoroughly the internal corrosion mechanism present in the system and their immediate causes. In this case, the main corrosion mechanism present is under deposit corrosion, which causes pitting damage at different positions along the pipeline. According to microscopic analyses, the pitting are related to the presence of sand and solids (iron carbonates and sulphides); and the location of the damage depends basically on the internal diameter of pipelines (the hydrodynamics of the system).

Chemical Engineering Research and Design

Papers showing how research results can be used in chemical engineering design, and accounts of experimental or theoretical research work bringing new perspectives to established principles, highlighting unsolved problems or indicating directions for future research, are particularly welcome. Contributions that deal with new developments in plant or processes and that can be given quantitative expression are encouraged. The journal is especially interested in papers that extend the boundaries of traditional chemical engineering.
