摘要

This report presents the findings of a number of studies on the qualitative effects on petroleum resulting from prolonged storage primarily in deep underground caverns, but also in aboveground tanks. These studies comprised a literature survey, discussions with scientific and technical personnel in various petroleum companies, and a comprehensive laboratory investigation of samples from several strategic reserve sites in West Germany. It is demonstrated conclusively that both crude oil and refined products can be stored for prolonged periods without undergoing deleterious changes in quality. The most practical and economic mode of storage is in caverns in salt deposits. Moisture is likely the single most significant contributor to petroleum degradation because it will harbor microorganisms and fungi which metabolize hydrocarbons. Long-term storage stability can be enhanced by selecting products which are inherently stable and are additive treated. The storage stability of the product should be thoroughly evaluated, and a monitoring program instituted to periodically assess the quality of the petroleum in storage. 40 refs., 13 figs., 8 tabs.
