| 压力容器，是指盛装气体或者液体，承载一定压力的密闭设备，柴油罐其范围规定为*工作压力大于或者等于0.1MPa（表压），且压力与容积的乘积大于或者等于2.5MPa•L的气体、液化气体和*工作温度高于或者等于标准沸点的液体的固定式容器和移动式容器；盛装公称工作压力大于或者等于0.2MPa（表压），且压力与容积的乘积大于或者等于1.0MPa•L的气体、液化气体和标准沸点等于或者低于60℃液体的气瓶；氧舱等。汽油柴油的胶质增多；润滑油的酸值增大；润滑脂的游离碱变小或产生游离酸等。 减少油品轻组分蒸发和延缓氧化变质的主要措施有：降低温度，减少如果要求不是很严格，没必要清洗。因为柴油和汽油从本质上来说都是石油的轻质裂解产物，化学性质非常接近，只是碳链的长短上的差异。如果要求严格，就用汽油本身清洗就够了。柴油是完全溶解于汽油的。（图/文http://www.wxfengli.com/） （中译英） Pressure vessel, means for gas or liquid, bearing pressure sealing device, its range is provided for a maximum working pressure greater than or equal to 0.1MPa (g ), and the pressure and the volume of the product is greater than or equal to2.5MPa •L gas, liquefied petroleum gas and maximum working temperature is higher than or equal to the boiling point of liquid standard fixed container and mobile containers; costumes nominal working pressure greater than or equal to 0.2MPa (g ), and the pressure and the volume of the product is greater than or equal to1.0MPa •L gas, liquefied gas and standard boiling point is equal to or lower than 60 ℃liquid cylinder chamber. Petrol and diesel oil glial increase; acid number of lubricating oil grease increases; the free alkali or small free acid. Reduce oil light component of evaporation and retard the oxidation of main measures are: to reduce the temperature of reduction, if not very strict requirements, no need of cleaning. Because of diesel and gasoline are essentially oil light pyrolysis products, and chemical properties are very close, but the carbon chain length differences. If the requirement is strict, with gasoline cleaning is enough. Diesel is completely dissolved in oil. |
