A Surface Science Approach Towards Understanding and Mitigating Fouling and Corrosion in Crude Oil Refinery Units
DownloadFall 2021
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...

Casing pipes used in sour service are prone to two forms of failure: hydrogen induced cracking (HIC) and sulfide stress cracking (SSC). The objective of this thesis is to investigate the resistance of L80 ERW and Seamless steel pipe, with five different chemical compositions, to both HIC and SSC....

The formation of bainite is the most studied and the most debated phase transformation in steels, with research spanning almost a century. With two theories of transformation, the transformation mechanism of bainite is still a disputed subject among physical metallurgists. Upper bainite and lower...

Modeling of the Effect of Run-out Table Cooling on the Microstructure of a Thick Walled X70 Skelp
DownloadSpring 2018
This thesis presents work performed to model and measure the effect of run-out table cooling on a thick walled X70 steel. During run-out table cooling, the steel undergoes several phase transformations that will affect its microstructure, and thus, its mechanical properties. To predict the steel...

Fall 2011
Optimization techniques, in conjunction with a finite element thermal model, are used in this thesis to optimize the temperature profile (i.e. cooling rate and coiling temperature) of a steel skelp during laminar cooling. Optimization parameters include skelp velocity, laminar cooling bank...

The Role of Sulfur Species in Establishing the Corrosion Reactions in Refinery Metallurgies
DownloadSpring 2016
This thesis is focused on the studying the role that model sulfur-containing molecules have in corrosion reactions on relevant metallurgies. This was done by using a design of experiments where a number of sulfur-based compounds were reacted with various metallurgies. The 8 model sulfur compounds...

ML80 and Grade 483 are heat treatable steels, produced by a quench and temper process, that are used in the oil and gas industry. The development of the microstructure during heat treatment is important to ensure that the correct properties are achieved for these steels. However, a real-time...
