Effect of an Inhibitory Additive on the Formation of Asphaltene-Resin-Paraffin Sediments in Highly Paraffinic Oil

An effect of inhibitory additive on the kinetics of sediment formation in highly paraffinic oil was investigated. It has been demonstrated that the maximum rate of sediment formation occurs within the first minutes of the process. The inhibitory additive promotes greatly decreasing to a considerable extent the rate of sediment formation in the oil due to the retention of solid paraffin hydrocarbons in the bulk. An influence of the inhibitory additive upon the group composition of sediments and the composition of paraffinic hydrocarbons was investigated.
