摘要
针对大连口岸近年来出口的石脑油,分析了出口石脑油主要项目的检验结果。结果表明:每年出口石脑油中的密度、终馏点、环烷烃含量等检验项目批次间的极差值在缩小;密度、芳烃含量等检验项目的平均值在下降;硫含量、初馏点、烷烃含量在增大;铅、汞、砷、氯含量变化不大;每批次各项指标检验结果值不尽相同,但都在合同规定范围内。
Focused on the naphtha exported from Dalian port recently, inspection results for major items of export naphtha were analyzed. The results show that：the annual differences between batches of inspection items of density, end boiling point, cyclane content in export naphtha is decreasing. The mean value of inspection items of density and cyclane content is declining. Sulfur content, initial boiling point and alkane content is increasing. The content of lead, mercury, arsenic and chlorine remains constant. All the inspection index results complied with provisions of the contract, although with various values.
