Additives to Prevent Deleterious Effects Associated with Long-Term Storage of Petroleum Products

The objectives of this study are to present the deleterious effects of long-term storage of crude oil and petroleum products and to suggest products and process modifications which will minimize or eliminate the negative effects of such storage. Specific additives, treatment rates, and cost are provided when available. The literature was reviewed to evaluate the available information for data from theoretical and research studies to determine what means of treatment would prove to be most applicable. This review was supplemented by discussions with military and civilian experts familiar with the chemistry and stability of petroleum and additive compounds, and a compilation of information on currently marketed additives. The criteria used in evaluating the potential of the various methods or processes found in the literature included: the anticipated ability of a process or additive to prevent significant deterioration of the product, the feasibility of the process or additive, the compatibility of processes and additives and the deleterious effect of additive components on other storage parameters. This report includes the results of the literature review, the specific literature available from commercial sources, preliminary cost estimates, a bibliography, and recommendations with regard to additional steps to evaluate stabilizing additives.
