Composition analysis of asphaltene-resin-paraffin deposits of different genesis and the ways of their utilization

摘要

Asphalt, resin and paraffin deposits (ARPD), formed during refining processes, transportation and oil storage represent a serious problem for the oil producing and refining companies from technical, economic, and ecological points of view. Their performance characteristics is the important factor defining efficiency of measures aimed to remove ARPD and the ways of their further use. The current work investigates ARPD physical and chemical properties and group chemical composition of ARPD of a refinery and oilfield origin. The interrelation between ARPD chemical composition and their physical and chemical properties is shown: namely, density, fusion temperature. It is established that ARPD properties are defined not only by the the quantitative content in deposits of high-molecular components: paraffin, raisins and asphaltens, but also their qualitative structure and a mutual proportion. Results of test of two ARPD samples with different chemical compound as protective coatings are presented. It is shown that ARPD with prevalence of polar components in their structure approves the best operational properties: higher adhesion to metal, and better corrosion protection
