Abstract Located on the Cook Inlet, 60 miles southwest of Anchorage, the Tesoro Kenai Refinery can process up to 72,000 barrels per day (bpd). The refinery produces gasoline and gasoline blendstocks, jet fuel, diesel fuel, heating oil and heavy fuel oils, propane and asphalt. Pursuant to the forthcoming Consent Decree settling certain claims between the United States and Tesoro Alaska Company LLC ("Tesoro"), Tesoro contracted with IMACC, LLC to conduct a combustion efficiency performance test on the air-assisted Main Refinery flare at its Kenai Refinery. The main objective of this test was to prepare a combustion efficiency performance curve for the flare over a range of flare operating conditions. The performance test measured the air-assist rate provided by the current fan and fan motor, and assessed the combustion efficiency of the flare under varying vent gas flow rates of differing calorific values and different assist-air flow rates. During each test condition, the PFTIR remotely analyzed the resulting combustion gases in the flare plume to determine combustion efficiency. Data from the performance test are used to:;  Provide a detailed description of the extent to which the ratio of mass flow rate of air to the stoichiometric air flow for the vent gas (ṁair-asst/ṁair-stoich-vg) affects combustion efficiency;;  Provide a detailed description of the range of the ṁair-asst /ṁair-stoich-vg that the Kenai Air-Assisted Flare can operate to ensure a minimum 96.5% Combustion Efficiency (or as high an efficiency as reliably obtainable), taking into consideration variability in Vent Gas flow rate and composition; and;  Describe the maximum ṁair-asst/ṁair-stoich-vg at which Tesoro proposes to operate the Kenai Air-Assisted Flare.; The presentation will highlight the unique features of testing an air-assisted flare equipped with a variable speed drive under flare conditions of varying calorific values and volumetric flow rates.
