成品油零售企业则可根据市场实际供求状况,以零售基准价为基础,在上下8%的浮动幅度内自主制定汽、柴油的具体零售价格。

成品油标准密度:ρ4t=ρ420-α(t-20),ρ4t:t℃时的密度(相对于4度时纯水密度之比),α:温度修正系数

产品按空气中的质量计算数量,当在非标准温度下使用石油密度计测得产品的视密度时,应该用表59B查取该产品的标准密度(ρ20)。

在计算产品数量时,产品在计量温度下的体积通常要换算成标准体积。产品的标准体积(V20)用计量温度下的体积(Vt)乘以计量温度下的体积修正到标准体积的体积修正系数(VCF20)获得,而体积修正系数是用标准密度和计量温度表查表60B获得的。

换算关系:

1桶(bbl)=42加仑(美制)=159升(l)=0.159立方米(m3)

1桶(bbl)=0.137吨(t)=137公斤(kg)(全球平均)

1吨(t)=7.35桶(bbl)(全球平均)=1174升

1升(l)=0.246加仑(Gal)

1公斤=0.3055加仑(美)/0.2545加仑(英)

注意事项:

1、成品油的存贮要按照其性质、要求和消防施救方法的不同严格分类独立存贮于特殊专用的危险品仓库中。多种成品油混存时,可能会因包装容器渗漏等原因,造成性质相触的两种或两种以上的成品油发生化学反应,最终酿成安全事故的发生。

2、成品油在仓库存贮过程中发生的溶化、变质、挥发等现象,几乎都与空气的温湿度有密切关系,因此仓库的通风、干燥及温湿度等条件的把控是成品油存贮的核心重点工作。

3、由于成品油的物理化学性质不同,其所适应的温湿度要求也不同,企业进行成品油的仓库存贮时,要有针对性、计划性存贮,如氢氧化钠、氢氧化钾等物品,要注意密封,维持湿度平衡。

4、由于成品油本身存在的安全特殊性,因此在危险品的装卸、搬运、堆码过程中,要严格遵守相关的操作要求和合规的工序流程进行操作,做到持证上岗,不得随意撞击、拍打、拉扯,要做好个人安全防护措施,穿戴好个人防护用品。
