摘要：对原油电脱盐中采用化学试剂脱铁的过程进行研究,探索化学试剂结构和铁的存在形式与脱铁效率之间的关系,考察脱铁过程的主要影响因素。结果表明,铁脱除率不仅与试剂的配位能力即配位体的官能团种类、形成螯合环的大小、数目和结构相关,还与铁在原油中的分布和存在形式有关。正交实验结果表明,各因素对脱铁效果影响由大到小的顺序为:试剂用量>pH 值>反应温度>反应时间;试剂加入量越大、反应时间越长、温度越高,油溶性铁的脱除率也越高,试剂pH 值为2左右最有利于铁的脱除。
The removal of oil-soluble iron from crude oil with chemical agent was investigated. The effects of the structure of chemical agents and the existed form of the oil-soluble iron on the removal rate were analyzed. The results showed that the iron removal rate was not only depended on the coordination effect of the agent, such as the types of functional groups, the size, number and structure of the formed chelating ring,but also depended on the existed form and distribution of the iron compounds in crude oil. The results of experiments designed with orthogonal method showed that the effect of these factors from great to less were in the order of agent dosage pH value reaction temperature reaction time, i. e. the removal rate of oil-soluble iron was proportional to agent dosage, reaction temperature and reaction time. Chemical agents having pH value around 2 were preferred for removing oil-soluble iron.
