One of the main concerns with lubricating oil relates to used oil management for both industrial and engine oils, although the environmental impact of gasoline and diesel engine oils is the most critical. Provided that efficient management systems are in place, most used oil should not reach the environment, so, the major question is how to dispose of collected used oil. The first option lies in burning it as a fuel, the second in recycling (reclaiming, reprocessing, re‐refining). The latter allows recovery of mineral base oils, which are valuable constituents of crude oil. Mobile (on site) and fixed plants for industrial oil recycling will first be discussed, and the paper will look at the most modern re‐refining processes that produce base oils of as high quality as virgin base oils. Based on current re‐refining experience, the quality of finished lubricants blended from re‐refined base stocks is also noted. Re‐refining today may be of significant benefit to the economy and can, of course, protect the environment. All modern re‐refining technologies produce small amounts of by‐products in which toxic materials may have been concentrated. A final aspect of reprocessing used oil is to integrate it, after hydrogen treatment, into existing refineries. This valuable raw material can then be directly routed to a lube oil unit or even to a cracking unit for conversion to gasoline. The integration of used oil treatment processes into selected refineries may be the most effective pathway to used oil disposal. In this first part, the author looks at the nature of the problems associated with used oil, its use as a fuel, and simple recycling. He then goes on to look at major re‐refining processes, starting with hydrogenation (KTI, Mohawk, BERC/NIPER, and PROP technologies). Part 2 will describe other processes, including a range of vacuum distillation/clay treatment technologies. 相似文献

吸附管/气相色谱/质谱法分析纵火案的纵火剂残留物 总被引:1,自引:0,他引:1
用吸附管(AT)/气相色谱(GC)/质谱(MS)法检测纵火残留物中轻质矿物油是通过吸附管动态吸附检材中可挥发的有机物,然后通过热脱附将挥发物送至GC及GC/MS中检测。它既适用于轻组分的碳氢化合物,如汽油,也适用于较高分子的碳氢化合物,如柴油和煤油。用沸石预处理样品克服了样品中水分对鉴定的干扰。用本方法能够得到比过去所使用的溶剂提取法或顶空法(HS)更高的吸附效率和灵敏度,解决以往由于残留物中热解产物干扰所造成的GC图形混乱复杂,难以准确分析鉴定的问题。用本方法分析纵火或火灾案件中常见的残留物——轻质矿物油,具有快速、灵敏、准确和简便等特点,可广泛用于公安、司法和保险等各个领域。 相似文献
