Abstract
BC (smake particulate) was measured in the emissions from the Rolvsnes well test flare from the 6th - 9th of August 2018. Approximately 90% of the measured particulate matter was in the PM I range (1 micron in diameter and smaller). Smoke particulate this small can stay airborne for considerable time. The flare emissions contained little visible smoke. An instrumented hexacopter drone was utilized to collect smoke plume data that would enable a calculation of a BC emission factor. A constant feed rate of 620 m3 of oil and 81,000 m3 of natural gas per day was reported for the Rolvsnes well test flare. The calculated BC emission factor derived from an array of transects through the well test flare smoke plume ranged from: 0.42 to 0.84 kg BC per tonne of combined oil and gas; and 0.48 to 0.96 kg BC per tonne of oil (this emission factor, relative to oil, is conservative as it incorrectly assumes no contribution of gas combustion or to a lesser extent platform diesel combustion to BC). No visible evidence was observed that would indicate any oil fallout from the flare to the sea surface.
