油品的蒸发损耗是自然损耗,蒸发损耗主要来自储油罐的大呼吸损耗和小呼吸损耗。油品损耗不仅在数量造成损失,还将影响油品的质量,而且大量的油品蒸汽散失于大气中,会造成严重的环境污染,并构成潜在的火灾危险。本文主要讨论了油品呼吸损耗的类型、影响因素、危害、呼吸损耗的测量和计算以及降低油品蒸发损耗的措施。 Evaporation loss of oil products is a natural loss, evaporation loss mainly comes from the large respiratory loss and small respiratory loss of the storage tank. Oil loss not only causes the loss in quantity, but also affects the quality of oil products. Moreover, a large amount of oil vapor is lost in the atmosphere, causing serious environmental pollution and posing a potential fire hazard. This article mainly discusses the types, influencing factors, hazards, the measurement and calculation of respiratory loss and the measures to reduce the evaporation loss of oil products.
