油品在线调合系统已经在全球各大炼油厂大规模实施,并取得了很大的投资回报率,经过十几年不断完善,汽油在线调合技术已经非常成熟,在国内也逐渐得到成功应用。兰州石化于近年正式投用了汽油在线管道调合系统,该系统采用在线检测NIR近红外分析仪系统和DCS集散控制系统,实现在线测定组份油的辛烷值等质量指标以及控制管道调合成品油的质量指标,随时优化和控制调合配方,使调合后成品油的辛烷值等质量指标达到设定目标控制值的一种在线管道优化调合方式,通过这种调合方式来挖掘汽油组份辛烷值的潜力,避免汽油辛烷值超标而造成质量过剩的一项新的调合技术。
The oil blending system has been implemented on a large scale in large-scale oil refineries all over the world and achieved a great return on investment. After more than 10 years of continuous improvement, the blending technology of gasoline has been very mature and gradually been successfully applied domestically . In recent years, Lanzhou Petrochemical has formally put into use a gasoline online pipeline blending system. The system uses on-line detection of NIR near-infrared analyzer system and DCS distributed control system to realize the online determination of the octane number and other quality indexes of the component oils and the control of pipe blending The quality index of the product oil can be adjusted and controlled at any time to make the quality index of the product oil after blending meet the target control value. Excavating the potential of octane number of gasoline components and avoiding over-mass caused by excessive octane value of gasoline A new blending technology.
