This study evaluates emission characteristics of volatile organic compounds (VOCs) caused by standing loss ( L) and working loss ( L) of three vertical fixed-roof p-xylene ( p-X) liquid tanks during 1-year storage and filling operation. The annual net throughput of the tanks reached 70,446 t, resulting in 9,425 kg of p-X vapor emission including 5,046 kg of L (53.54 %) and 4,379 kg of L (46.46 %). The estimated L of AP-42 displayed better agreement with the measured values of a VOC detector than the estimated L of AP-42. The L was best correlated with the liquid height of the tanks, while the L was best correlated with the net throughput of the tanks. As a result, decreasing vapor space volume of the tanks and avoiding high net throughput of the tanks in a high ambient temperature period were considered as effective means to lessen VOC emission from the fixed-roof organic liquid storage tank.
