High Temperature Oxidation Kinetics Of Alumina Forming Steels For Petrochemical Processes, Kao Zoua Yang
Theses and Dissertations
Petrochemical industries produce 14.33 million barrels of petroleum products a day and by 2023, are expected to produce over a trillion dollars in sales annually. Petroleum is the number one used fuel source and is the raw material used to produce a wide range of petrochemical products including ethylene which is the raw chemical precursors that is crucial to the polymer market. Ethylene is created by the process of cracking ethane and other hydrocarbons in steel reactors at high temperature and potentially oxidizing conditions. The cracking process produces a range of byproducts including a detrimental solid carbon, called coke, which …

Uncertainty Quantification And Constraint Of Chemical Kinetic Mechanisms Based On Flow Reactor Experiments, Ana Victoria Kock
Theses and Dissertations
The chemical kinetic model is one of key sub-models for computational fluid dynamics (CFD) simulation for optimizing and designing various combustors/engines. Detailed chemical kinetic models can consist of hundreds of species and thousands of elementary reaction steps. Considering the complexity in these detailed chemical kinetic models, it is important to quantify and minimize the uncertainties in the kinetic parameters. The uncertainties in the kinetic models can then be compared to uncertainties tied to experimental measurements. This approach has been frequently applied for relatively simple combustion parameters (e.g., laminar flame speed, ignition delay time), however it has not been well utilized …
