Flaring Performance

Dave Lye, AEC

This project is an extension of a major research program, started in 1996, to determine the nature, existence and amounts of potentially harmful products of incomplete combustion. One of that program’s many studies investigated factors influencing the combustion efficiency of flares, with the aim of helping industry and regulators establish practical performance measures and operating practices for flares.

A key component of the earlier flare performance projects was to develop methods for measuring the efficiency of flares subject to crosswinds and containing liquid fuel droplets in the flare stream under laboratory conditions. As well, models were developed to predict flaring efficiency under various conditions.

This new, extended project is primarily looking at what happens when wind tunnel tests are expanded from a one-inch to a four-inch flare pipe typically used in solution gas flaring. The aim is to see how the earlier, one-inch tests stand up in real-world conditions and thus give the petroleum industry and regulators confidence those early results and models are valid.
