摘要: 通过热化学沉降脱水脱除了原油中的无机氯化物;利用微库伦滴定仪对辽河石化公司不同装置原
油/馏分油中的氯质量分数进行了测定,结合其收率进行配分计算得出了氯的分布规律。实验结果表明,不同装置
加工的原油种类和来源的不同导致其氯质量分数不同,东蒸馏装置原油中氯质量分数最高,达到12.94μg/g,焦化装
置原油氯质量分数最低,仅3.9μg/g;东蒸馏装置和南蒸馏装置原油中的氯以无机氯居多,分别占总氯质量分数的
62.13%和60.08%,而西蒸馏装置原油中的氯以有机氯居多,占总氯质量分数的72.14%;氯分布在原油的所有馏分
中,重馏分中比例较高,说明原油中的氯是以复杂的混合物形态存在。

Abstract: The inorganic chlorine was removed from crude oil by thermochemical deaquation process. The chlorine contents in Liaohe crude oil and its distillates were determined using microcoulometric titration, and the chlorine distribution combined with the yield were calculated. The analysis results demonstrate that the chlorine contents varied with the difference of types and origin of crude oil. Chlorine content of crude oil in east distillation unit is high up to 12.94 μg/g, and that of coking unit is only 3.9 μg/g. Most of the chlorines in crude oil of east and south distillation unit are inorganic chlorines, and the proportion is 62.13% and 60.08%, respectively. The contents of organic chlorines in west distillation unit is higher, and the proportion is 72.14%. Chlorines distribute in all crude oil fractions, and they mainly exist in the heavy fractions. The distribution result demonstrates that the chlorides in crudJIe oil exist with complex mixtures.
