摘要
本文介绍了我国主要原油以及各馏分油中金属的分布。原油的脱盐效率,除过去以Cl^-含量作为衡量指标外,还应考虑到碱及碱土金属在脱盐过程中的脱除程度。实验证明,原油中钙的脱除率较低,对下游操作将会产生影响。应研制针对性较好的脱除剂和灵敏、快速的测定金属离子的方法。
This paper presents the distribution of metals in major Chinese crudeoils and their fractions.In addition to the Cl^- content which is usually usedas a measurement of the desalting effciency,the extent of removal of alkaliand alkaline earth should also be concerned with.Experiment results confirmthat calcium is rather difficult to remove from the crude oil and thus hasharmful effects on downstream proccessing.It is necessary to find an efficientagent for cacium removal and to establish a sensitive,rapid method for thedetermination of metal ions in crude oil.
