Abstract

A system to convey a fluid, in particular a fluid containing hydrocarbons, has a first pipeline, which is made of an electrically conductive material and has an internal diameter; a second pipeline, which is made of an electrically conductive material, has an external diameter smaller than the internal diameter, and is placed inside the first pipeline at a distance from the first pipeline so as to form an annular gap between the first and second pipeline; an electrically conductive layer placed in the annular gap at a distance from the first pipeline; an electrically insulating layer placed between the second pipeline and the electrically conductive layer; and a power source to apply an electrical potential difference between the second pipeline and the electrically conductive layer.

Dependent claims

A system to convey a fluid, the system comprising:

a first pipeline made of an electrically conductive material and having an internal diameter;
a second pipeline made of an electrically conductive material and having an external diameter smaller than the internal diameter of the first pipeline, the second pipeline being positioned inside the first pipeline at a distance from the first pipeline to define an annular gap between the first pipeline and the second pipeline;
an electrically conductive layer positioned in the annular gap at a distance from the first pipeline, the electrically conductive layer being in electrical contact with the first pipeline;
an electrically insulating layer positioned between the second pipeline and the electrically conductive layer;
and
a power source configured to apply an electrical potential difference between the second pipeline and the electrically conductive layer.
