Abstract The goal of this work is to seek improvements in the design of a proposed coal gasification plant with carbon capture by more efficiently harnessing the available heat for power production or utilities. The focus is placed on improving heat integration and developing innovative thermodynamic cycles by using new working fluids to increase the efficiency of the plant. Design of the utility system is important for any chemical, power or cogeneration plant. Steam is often used to meet the process heating or cooling requirements, or used as a medium to transfer heat between processes. Therefore, this work examines optimum steam generation which in turn reduces fuel consumption and increases power generation. In addition, working fluids that differ from the conventional steam Rankine cycle such as organic fluids can be used to allow for a better thermal matching (i.e. similar temperatures and temperature profiles) between the heat sources in the plant and the power cycle. Another innovation examines new and better ways to capture the heat in the gasifier radiant heat exchanger. Harnessing the high temperature heat available in the gasifier is very attractive for either power generation or hydrogen production. Miss Botros’s research interests include the application of thermodynamics, heat transfer and fluid mechanics to the energy sector, including renewable fuels, power generation, combustion and turbomachinery. She is currently pursuing a PhD in Mechanical Engineering at MIT focused on improvements in heat integration and power cycle innovations of a proposed coal gasification plant with carbon capture. Miss Botros also conducted research in the Gas Turbine laboratory during her Master’s at MIT to quantify the unsteady flow field in high speed axial compressors. While at McGill, Miss Botros studied compressible reactive flow, exemplified in her undergraduate thesis which examined the response of a detonation wave when perturbed by a normal shock wave. She graduated with the highest honor in the Faculty of Engineering from McGill, earning the gold medal for highest ability throughout the undergraduate program. During her time at MIT, Miss Botros served as President of the Graduate Association of Mechanical Engineers, and in a number of other leadership roles. Her thesis supervisors include Prof. John G. Brisson during her PhD, Prof. Edward Greitzer and Dr. Choon Tan during her MS, and Prof. John HS Lee during her undergraduate honors thesis. |
