研制了一种可用于石油产品中芳烃含量在线检测的紫外分析仪，仪器采用凹面全息光栅双单色仪和独特的进样系统，可保证吸光度高达７Ａｂｓ的润滑油样品在石油生产现场不经稀释即可进行在线分析检测。经五年多工业现场使用，准确率达９５％，无故障运行率达９７％以上。为润滑油生产过程质量监测、优化操作，为光谱技术在石化工业应用开辟了一条新路。 A UV analyzer for on-line detection of aromatics in petroleum products was developed using a concave holographic grating dual monochromator and a unique injection system to ensure undiluted samples of lubricating oil with an absorbance of up to 7 Abs at the oil production site You can conduct online analysis and testing. After more than five years of industrial use, the accuracy rate of 95%, trouble-free operation rate of 97% or more. For the lubricating oil production process quality monitoring, optimization of operation, opened up a new road for the application of spectroscopy in the petrochemical industry.
