Corrosion Of Oil Pipeline: A Case Study On The Niger Delta Region Of Nigeria., Victor U. Okoro Nov 2023

Corrosion Of Oil Pipeline: A Case Study On The Niger Delta Region Of Nigeria., Victor U. Okoro

Corrosion Research

Corrosion of oil pipelines in Nigeria, particularly in the Niger Delta region, has extensive and detrimental environmental and societal impacts. This issue results in substantial financial losses and reputational damage for oil companies operating in the area. Local communities suffer economically, affecting agriculture and food security. Furthermore, corrosion-related oil spills lead to air quality degradation by releasing volatile organic compounds and greenhouse gases, contributing to respiratory issues and worsening climate change.

These oil spill cleanups are costly and time-consuming, with estimated expenses reaching billions of dollars. Using the Nembe Creek Trunk Line (NCTL) case study, it is evident that addressing …


Corrosion Case Study On Pipeline, Kangze Ren Oct 2023

Corrosion Case Study On Pipeline, Kangze Ren

Corrosion Research

The Kashagan pipeline leaks were likely caused by sulfur stress corrosion cracking, a combined corrosion mechanism developed by the presence of high pressure, the high level of hydrogen sulfide(the main "ingredient" of sour gas), and poor metallurgical choice. Improper welding and poor metallurgical examination were blamed for causing the leaking issue. The purpose of the current review is to raise the alarm about the inappropriate corrosion management of Kashagan oil production and its societal and environmental consequences.


Near-Ir Laser Ablation Of Simulated Radiologically Contaminated Oxides On Carbon Steel Feeder Pipes, Thao Viet Do Nov 2022

Near-Ir Laser Ablation Of Simulated Radiologically Contaminated Oxides On Carbon Steel Feeder Pipes, Thao Viet Do

Electronic Thesis and Dissertation Repository

As nuclear power plants age and retire from service, many countries face significant challenges concerning the safe long-term storage and disposal of large volumes of low and intermediate level radioactive wastes (L&ILW). The volumes of metallic waste are of particular concern, as when metal corrodes it produces hydrogen that could lead to pressure build-up in interim storage and disposal. In Canada, a significant fraction of the metallic wastes for Canada Deuterium Uranium (CANDU) nuclear reactors are out-of-core reactor components, such as carbon steel (CS) feeder pipes. The radioactive contamination is expected to be largely confined to the surface oxide layers …


Surface Modification Of Aluminum Alloys By Plasma Electrolytic Oxidation, Vahid Dehnavi Aug 2014

Surface Modification Of Aluminum Alloys By Plasma Electrolytic Oxidation, Vahid Dehnavi

Electronic Thesis and Dissertation Repository

Plasma Electrolytic Oxidation (PEO) is a surface treatment for the production of ceramic oxide coatings with great properties, such as high wear and corrosion resistance, on metal substrates, particularly aluminum and magnesium alloys. Formation of PEO coatings involves complex processes and mechanisms that are difficult to study. Currently, the PEO process is in a transition phase from research to commercial application, with a primary focus on the corrosion and wear protection of light alloys, and has recently generated interest as a promising surface treatment for biomedical applications.

To justify the industrial application of PEO, a more systematic and in-depth study …
