Paraffin blockage specificsin model petroliferous systems

摘要

In this paper we study the effect of the temperature factor, the content and composition of the dispersed phase components: paraffinic hydrocarbons, resins and asphaltenes, - on the sedimentation process in model systems. Adding a 0.025 to 0.1 wt.% of resins and asphaltenes doping agent to a 20 wt.% paraffin wax solution in kerosene shall be optimalto resist precipitate formation. Asphaltene and resin compositions, derived from the methane-kind petroleum-oil, are characterized by a maximum ability to prevent sedimentation. The presence of resins and asphaltenes in a model system shall significantly affect the physical and chemical characteristics of the sediment.
