On Sunday, June 16th, we offer Short Courses on a wide variety of topics important to the energy community. Participation is optional; is included in the registration fee; and open to all conference registrants.
|Short Courses – To provide our attendees the latest in technological advances, we’ve invited industry experts to offer two-hour Short Courses intended to give an overview or specific details on topics of greatest interest to the industry. This year we are pleased to offer:|
|9:00 – 11:00 a.m. – Fundamental Experiments and Modeling for Direct-Fired Supercritical CO2Combustion, Prof. Subith Vasu, Center for Advanced Turbomachinery and Energy Research (CATER), University of Central FloridaThis short course will present fundamentals and review of recent efforts in the development and validation of a combustion chemical kinetic mechanism for sCO2 oxy-methane/syngas combustion that can be used for computational fluid dynamic code (CFD) simulations in sCO2 oxy-combustion development. Typical gas-phase combustion models for fuels (methane, syngas, etc.) have been validated for gas turbine conditions – pressures below 40 atm and in fuel/air combustion – and cannot be extended to the operating conditions of sCO2 combustors such as, those used in Allam cycle. Recent sCO2 models are created by incorporating real gas and solvent effects on combustion process using quantum chemical and molecular dynamic investigations. Validation is carried out using unique experiments conducted in CO2 diluted methane/syngas mixtures and for pressures up to 300 bar. Acquiring experimental data is critical in the development of a sCO2 detailed kinetic mechanism as there was previously none available for methane at very high pressures near 300 bar (for Allam cycle) and for CO2 diluted methane mixtures even at normal pressures. Challenges with coupling the mechanism to combustion CFD codes will be discussed. Such codes enable us to study a variety of topics regarding direct-fired sCO2 oxy-methane/syngas combustors and will be highly valuable and accurate tool for computer design optimization of next generation sCO2 combustors.|
|11:15 a.m. — 1:15 p.m. – Combustion Tuning: Why and How, Alan Paschedag, Covanta, Inc., and J.J. Letcavits, American Electric PowerThe process of combustion tuning is on the surface very simple. However, without an understanding of what makes combustion tick and what preparations must be made in advance, the results will not be ideal. A tour through combustion principles and what settings, adjustments, pre-planning, and fuel sourcing can do to optimize burner tuning.|
|1:30 p.m. – 3:30 p.m. – Catalysts and Sorbents for Pollution Control, Evan Granite, National Energy Technology Laboratory, U.S. Department of EnergyCatalysts and sorbents are widely employed in the processing of fossil fuels. Atoms and molecules are not faithful partners on the surface of a solid, with competitive adsorption (“forming a couple”), desorption (“kicking a spouse to the curb”), and reaction (“a most radical makeover”) occurring over, and over, again. The surface of a catalyst or sorbent is a “chemical soap opera”, and not for the faint of heart. The drama occurring on the surface of a catalyst, and its close cousin the sorbent, easily exceeds that of any Hollywood movie. Like the ancient marriage brokers, these solids help make extraordinary unions and transformations of atoms and molecules. Our modern economy would not be possible without these magical materials, and many important examples will be shown for the processing of coal, natural gas, and petroleum.
Catalysts or sorbents typically transform atoms and molecules through the Langmuir-Hinshelwood, Mars-Maessen, or Eley-Rideal mechanisms, and these will be illustrated. The “seven sacred steps” that occur during the use of any catalyst or sorbent will be shown. Poisoning, deactivation, pressure drop, sintering, mass and heater transfer, characterization techniques, regeneration, sorbent breakthrough curves, cost considerations, and future research challenges will be discussed. The instructor will make information available from his research, as well as his courses on chemical kinetics and petroleum and natural gas processing, available to interested students.
|3:45 p.m. – 5:45 p.m. – Combustion Fundamentals, Prof. Ashwani K, Gupta, University of Maryland This Short Course will cover fundamental aspects of combustion, including fuels and their fundamental properties, stoichiometric balances, adiabatic flame temperature calculations, flame stability and pollutants formation and mitigation. No prior knowledge on the subject will be assumed so that this tutorial will be very fitting to students and users of combustion devices in industry.|
