针对石油销售过程中油品蒸发损耗的严重性,对装油过程的油气损耗规律进行了现场考察和实验室研究,结果表明:所用油罐未清洗的排放气体积分数率平均高达64.17％,是已清洗油罐的1.7倍;高位喷淋装油平均排放气的体积分数高达40.58％,比低位潜没装油高1.4倍,且排放出的油蒸气和空气的混合气夹带有油雾;已清洗油罐低位装油时的损耗率为0.37％,高位装油为0.8％。油品因轻质组分的蒸发排放使其质量降低,并污染环境。 Aiming at the seriousness of the oil evaporation loss in the process of oil sales, the field study and laboratory research on the law of oil and gas loss in the process of oil loading were conducted. The results show that the integral percentage of the exhaust gas in the unused tank is up to 64.17% 1.7 times higher than that of the cleaning tank. The average discharge volume of the high level spray oil was 40.58% of the volume, 1.4 times higher than that of the low level submerged oil, and the mixture of oil vapor and air discharged was misty. Low oil tank wear rate was 0.37%, high loading of 0.8%. Evaporation of light components due to evaporation of oil reduces its quality and contaminates the environment.
