Coal Liquefaction Liquid Quality: Influence of Temperature and Heating Approach on Solvent Extraction of Coal
DownloadFall 2014
This project evaluated the impact of reaction temperature and of additional heating steps on the quality of the liquids obtained from solvent extraction of a lignite coal with tetralin. The points of focus were the coal liquid yield, physical properties, aromatic content and iron pyrite...

This thesis presents a thorough examination of the corrosion and fouling behaviour of crude oil at refining conditions on industrially applicable heat transfer surfaces. The depletion of light sweet crude oil reserves means that the processing of ever heavier and more sour crude oils is...

Mercury is an air pollutant emitted from coal fired power plants. Once released into the environment, mercury undergoes conversion to organomercury compounds, which cause health concerns for both humans and animals. Many studies have been completed with the goal of reducing mercury emissions...

Stainless steel is one of the most commonly used materials in most industries. Excellent corrosion resistance of stainless steel is due to the formation of an oxide film on the surface (passive film), which protects the material from continuous corrosion attacks. When subjected to an attack...

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...

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...

Traditionally in pipeline steels and welds, ultrasonic testing (UT) has been used for crack and/or flaw detection. The work presented in this Thesis explores the use of this technique to characterize the microstructure of pipe steels. Ultrasonic velocity calculations, for shear and longitudinal...
