Abstract

A process to clear pipelines carrying fluids viscous and/or rich in organic residues, utilizing heat generation through electric phenomena, whether or not combined with the injection of special fluids. The heating process of this invention includes basically the introduction of a heating element inside. a pipeline carrying fluids viscous and/or rich in organic residues, through a coupling spool which is intercalated in said fluid-carrying pipeline, simultaneously applying to said heating element an electric current, so that the heat generated by said heating element is transmitted to the viscous fluid or to the compacted residual mass inside the fluid-carrying pipeline, causing the detachment of those residues from the internal wall of the pipeline and reestablishing the conditions for fluid flow.
