ABSTRACT: Flare systems have a common prime objective: safe, effective disposal of waste gases and liquids. Flares act as a relief device when a plant must quickly dispose of product to prevent over-pressurization and potential explosions. Flaring capacities can range from less than 100 to more than 10 million lb/hr. Many flares have emergency relief flow rates that produce flames hundreds of feet long with heat releases of billions of Btus per hour. Material released into a flare system is often a mixture of multiple constituents that can vary from hydrogen to heavy hydrocarbons and may at times include inert gases. Flare systems are generally custom designed because of the wide range of conditions that exist in industry. Flares operate differently than most process combustion equipment and often in a much less controlled environment. There are many major design factors to be considered including for example: the waste gas composition may vary over a much wider range; a very large turndown ratio (sometimes 1,000:1 or more) is often required; and flares are typically operated at higher levels of excess air compared to other types of industrial combustion equipment. This presentation will include discussions of the various types of flares, flare system design, and environmental considerations. BIO: CHARLES E. BAUKAL, Jr., PhD, P.E., is the Director of the John Zink Institute. He has over 30 years of experience in the field of industrial combustion in the metals, minerals, petrochemicals, textiles, and paper industries. He has eleven U.S. patents and has authored/edited eight books on industrial combustion and written numerous technical publications. He holds BS, MS and PhD degrees in mechanical engineering and is a member of ASME, ASEE, and the Combustion Institute. He is an adjunct instructor at the University of Tulsa and Oral Roberts University and is a member of a number of advisory boards.
