一、内浮顶贮罐的产生及其优点油品在贮运过程中的蒸发损耗是相当可观的。据统计,1966～1968年苏联炼油和石油化学工业的原油和油品的损失为2.48～2.55%,对于炼油厂来说,原油和油品在贮罐中的蒸发损失占总损耗的80%。另据报道,在苏联由于油罐的“呼吸”,每年有7%的轻质油品损失掉。据全苏石油贮运研究所资料,各种固定顶贮罐的蒸发损失比例为:原油罐占20.4%,脱盐原油罐占31.6%,常压汽油中间罐占25.5%,常减压宽馏分油中间罐占13.2%,成品汽油罐占9.3%。
First, the production of floating roof tank and its advantages Oil evaporation loss during storage and transportation is considerable. According to statistics, from 1966 to 1968, the loss of crude oil and oil products in the Soviet Union’s refining and petrochemical industry was 2.48-2.55%. For refineries, the evaporation loss of crude oil and oil in storage tanks accounted for 80% of the total loss. It is also reported that 7% of the light oil products are lost every year in the Soviet Union due to the “breathing” of the oil tanks. According to the All-Russia Petroleum Storage and Transportation Research Institute, the evaporation losses of various fixed-top storage tanks are as follows: 20.4% for crude oil tank, 31.6% for desalted crude oil tank, 25.5% for atmospheric gasoline intermediate tank, Distillate intermediate tank accounted for 13.2%, finished gasoline tank accounted for 9.3%.
