Study on the efficiency of ARPD (asphaltene, resin and paraffin deposit) solvents when preparing pipelines for the transportation of petroleum products

Abstract

THIS PAPER EXAMINES THE PROBLEM of selecting efficient ARPD solvents in order to prepare pipelines for petroleum product transport. Solvents are used to remove deposits from the inner surface of the pipeline. The article proposes an approach which outlines the key characteristics of the solvents tested (rate of ARPD dissolution, cleaning efficiency, critical saturation concentration, dissolving capacity). The parameters obtained help to calculate the volume of ARPD solvent and contact time necessary to completely remove deposits from the surfaces being treated.
