Removal of liquid from solution gas streams directed to flare and development of a method to establish the relationship between liquids and flare combustion efficiency
This study was undertaken to examine technologies that could be used or developed to enable the upstream oil and gas industry to reduce the hydrocarbon emissions in the flaring of solution gas. The study objectives are to examine and evaluate possible surrogate methods for monitoring flare performance, review gas-liquid separation technologies available for solution gas cleaning, examine the application of numerical simulation for improving separator design, and develop a strategy for field testing of existing and improved solution gas cleaning technologies. Surrogate methods reviewed included either in-line systems of measurement for the hydrocarbon components known to reduce combustion efficiency, or an external remote measurement system for hydrocarbons and combustion products in the flare emissions. Separator technologies studied in a literature review included those based on gravity, centrifugal force, impacting or interception, and electromotive force. The capabilities and limitations of computational fluid dynamics in gas-liquid separator design are then discussed, and a series of projects is proposed for testing separation equipment or combustion efficiency measurement devices.
