Smokeless Flare Modeling of an Associated Gas in a Production Oil Field

摘要

In this paper the static and dynamic characteristics of an associated gas flare in production oil fields are analyzed. Effects of mass flow rate, flare tip diameter, flare stack height sizing and radiation distance covered heat librated into the environment and the physical characteristics of the associated gas were studied by modeling production oil field smokeless flare. A Mach's equation for normal condition is used for this investigation considering the effects of mass flow rate across the mixing chamber and for the simple approach method in the determination of the dimensionless number. The mathematical models were applied in the determination of the flare tip diameter, exit gas velocity, flare angle, and radiation effect. The models were found useful in predicting and monitoring the necessary parameters that favour smokeless flare for associated gas in a production oil field.
