Research Methodology in Used Oil Recycling

  • Donald A. Becker


Legislation and activities in the United States on the subject of used oil recycling have increased dramatically in the past several years. However, a substantial portion of both industry and government have some concerns about the lack of scientific and technical research and data on certain aspects of the quality and consistence of recycled petroleum oils, particularly re-refined engine oils. Further, there are some significant environmental concerns about pollution aspects of used oils and their recycling by-products and wastes. Since 1976, the (U.S.) National Bureau of Standards (NBS) has had a legislatively mandated program to “… develop test procedures for the determination of substantial equivalency of re-refined or otherwise processed used oil … with new oil for a particular end use” (42 U.S. Code 6363c). The NBS research includes identification of problem areas in the characterization of used and recycled oils, research into new measurement methods for determination of novel constituents in these materials, and the development and evaluation of appropriate test procedures and standards for recycled oil products. Aspects of this research discussed in this paper include analysis of total elemental content and speciation studies on lead and on the halogens (chlorine and bromine) and hydrocarbon type characterization studies on lubricating oil fractions.
