Ductile steel plate shear walls are an established lateral load resisting system. Past research indicates that cold-rolled infill panels less than 1 mm in thickness present one solution to an overstrength problem arising from selecting an infill panel thickness based on ease of welding and...

AC Dielectrophoresis, the motion of dielectric colloidal particles in the presence of an inhomogeneous AC electric field, has been utilized in this work as a mechanism for preventing channel wall fouling due to particle deposition for a multi-component colloidal system. Both attractive and...

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...

This thesis explored the properties of asphaltene nano-aggregates in crude oil and toluene based solutions and fouling at process furnace temperatures, and the links between these two phenomena. The link between stability of asphaltenes at ambient conditions and fouling at the conditions of a...

Coped beams are susceptible to fatigue cracking in the web at the cope radius when subjected to tension in the coped region. Use of an adhesively bonded composite patch over the crack can reduce the stress concentration and delay further crack growth. This report contains the results of a...

20Cr-32Ni-1Nb stainless steel alloys are commonly used in hydrogen reformer manifolds for transporting hot hydrogen by-products at 750-950 celcius. After long periods of exposure, embrittling secondary carbides and intermetallic phases can precipitate at the grain boundaries which can drastically...

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...

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...

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...

Athabasca oil sands contain 8 to 14% bitumen and are recovered using surface mining or steam assisted gravity drainage (SAGD). During primary upgrading of bitumen, the vacuum residuum from the distillation column is sent to the solvent de-asphalting unit where a paraffinic solvent is used to...
