对不同用途进口石脑油质量分析与研究
|
摘要
对不同用途的进口石脑油进行检验,数据处理结果表明:进口石脑油用于芳烃原料的环烷烃+芳烃含量平均值为47.09%,极差为22.49%,初馏点平均值为83.5℃,极差值为28.6℃;终馏点平均值为165.4℃,极差值为18.0℃;15℃密度平均值为0.748 4g/cm3,极差值为0.018 9g/cm3;硫含量平均值为58.2mg/kg,极差值为172.0mg/kg。用于生产乙烯原料的烷烃含量平均值为86.54%,极差为5.40%;正构烷烃含量平均值为40.10%,极差为10.83%;初馏点平均值为32.25℃,极差值为7.4℃;终馏点平均值为109.02℃,极差值为69.1℃;15℃密度平均值为0.673 2g/cm3,极差值为0.025 3g/cm3;硫含量平均值为49.6mg/kg,极差值为109.8mg/kg;铅、汞、砷、氯含量较低。检验结果都在合同规定范围内,建议应进一步分析个别批次的硫含量偏高的原因,并建议生产商和进口商控制和降低进口石脑油个别批次中的硫含量。
Data processing on inspection results of import naphthas of different uses revealed that:for import naphtha used as raw material of arene,average content of cyclane and arene in import naphtha was 47.09%,with a range of 22.49%;average initial boiling point was 83.5℃,with a range of 28.6℃;average final boiling point was 165.4℃,with a range of 18.0℃;average 15℃density was 0.748 4g/cm3,with a range of 0.018 9g/cm3;average content of sulfur was 58.2mg/kg,with a range of 172.0mg/kg.For import naphtha used as raw material of ethylene,average content of alkane was 86.54%,with a range of 5.40%;average content of normal paraffin was40.10%,with a range of 10.83%;average initial boiling point was 32.25 ℃,with a range of7.4℃;average final boiling point was 109.02℃,with a range of 69.1℃;average 15℃ density was 0.673 2g/cm3,with a range of 0.025 3g/cm3;average content of sulfur was 49.6mg/kg,with a range of 109.8mg/kg.Contents of lead,mercury,arsenic,and chlorine were relatively low;all inspection results lay in the range specified by the contract.It is suggested to further investigate the reasons of the naphthas with higher sulfur and recommended producer and importer to control and reduce the sulfur content of a few batches of import naphthas.
