摘要
通过对塔河稠油中氯盐的存在形态进行分析,发现其中不仅存在无机氯盐,而且存在有机氯盐,有机氯盐所占的比例在50%以上。用常规水洗脱盐的方法不能彻底脱除有机氯盐。有机氯盐在蒸馏过程中主要进入渣油中。开发了有针对性的脱氯助剂H,考察了脱氯助剂H对塔河原油的脱氯效果和对破乳过程的影响。结果表明,脱氯助剂H与破乳剂联合使用可以将脱后油的总氯质量分数降低到10gμ/g以下,盐(NaCl)质量浓度降低到3mg/L以下,并对破乳过程无不利影响。
The existing forms of chloride salt in Tahe crude oil and their sources were analyzed and an assistant agent H for organic chloride removal was developed and tested. It is found that there are two forms of chloride salts in Tahe crude oil: inorganic and organic chloride and that the content of organic chloride is above 50%. The organic chloride cannot be completely removed by traditional method and mainly goes into residual oil fraction during distillation. The test results show that the agent H with demulsifier together can decrease the chloride content in treated oil to less than 10 μg/g and salt content to less than 3 mg NaCl/L. Meanwhile it has little disadvantageous effect on demulsification.
