A Surface Science Approach Towards Understanding and Mitigating Fouling and Corrosion in Crude Oil Refinery UnitsDownload
This research presents a detailed investigation of corrosion and organic fouling on several important metallurgies in a broad range of crude oils. Throughout a refinery, fouling of metallic heat-transfer surfaces is a ubiquitous, costly, and complex phenomena, made increasingly challenging by...
As the Supercritical Water-cooled Reactor (SCWR) shows a promising future, the corrosion behavior of candidate materials has attracted great interest. In this study, experimental investigation was conducted to evaluate the corrosion behavior of the ferritic-martensitic steels designed for the use...
The present research has been done with the intent of evaluating the corrosion resistance and cracking susceptibility of some commercial candidate alloys that can be potentially used in Gen-IV supercritical water reactor (SCWR). The mechanism of the crack initiation in austenitic alloys exposed...
Creation and Characterization of Ceramic/Polymer Bi-Continuous Composite Material for Hot-Bitumen Pipeline CoatingDownload
Current composite materials base their capabilities from the dispersion of discrete reinforcing materials throughout a matrix. This method places too much reliance on the surface bond between matrix and reinforcing phase. By employing two continuous, interpenetrating materials, it is theorized...
Near neutral pH Stress Corrosion Cracking (NNpHSCC) on underground oil and gas pipelines is an issue facing industry today. Determining where NNpHSCC is likely to occur and grow is an important aspect to developing an Integrity Management Program. This work focused on developing a predictive...
Effects of Oxide Additions on the Corrosion Behaviour of Cr2O3 Based Ceramics in High Temperature Supercritical Water EnvironmentDownload
This investigation is aimed at developing ceramic materials applied in supercritical water, which is being considered as coolant for one of the next generation nuclear reactors. Cr2O3, a primary protective film on stainless steels, was found to be unstable in SCW due to the formation of soluble...
Coating disbondment on pipelines is a common phenomenon that leads to exposure of the pipeline metal to the surrounding soil and ground water solutions. The exposure of pipelines to those corrosive environments is associated with development of corrosion and Stress Corrosion Cracking (SCC) on the...
Investigation of Surface Crack Growth Behaviour Under Variable Pressure Fluctuations in Near-Neutral pH EnvironmentsDownload
The goal of this investigation was to study the corrosion fatigue behaviour and mechanisms of surface cracks, semi-elliptical in shape, when exposed to near-neutral pH environments conducive to the environments experienced in the field. To better simulate field conditions, while avoiding the...
This research is aimed at understanding near-neutral pH SCC initiation under disbonded coatings of pipeline steels, and the effect of different environmental and operational factors on crack initiation. Understanding near-neutral pH stress corrosion cracking (SCC) could answer many of the...
Sequencing & Agglomeration of Cycles in Variable Amplitude Underload Spectra: Effects on Surface Crack Growth in a Near-neutral pH EnvironmentDownload
Stress corrosion cracking (SCC) is one of the biggest integrity threat facing pipelines. Large numbers of SCC defects are detected every year, but scheduling the repair work for these defects is an enormous challenge. Pipeline companies have limited resources to take on the repairs. Therefore the...
