DEVICE FOR EVALUATING ELECTRIZATION OF LIQUID OIL PRODUCTS Russian patent published in 2018 - IPC G01N33/22 H05F1/00 

FIELD: oil and gas industry.

SUBSTANCE: device comprises a sealed two-stage chamber, in the larger-diameter stage of which there is a generator of electrostatic charges in the form of a vessel with a movable electrode fixed on a fixed metal rod connected to an instrument for measuring electric current. A movable electrode is made in the form of N rotating cascade-shaped hollow cylinders made of foamed nickel. Hollow cylinders are connected to the fixed metal rod by slider bearings under each of which a mercury current collector is installed. The vessel with the movable electrode is made through, with a hole in the bottom and has diametrically arranged branch pipes in the bottom part of this stage for feeding oil product to said vessel. A nozzle for tangential feed and swirling of the oil product is mounted on each branch pipe perpendicularly to it in the horizontal plane. On the outer side of the sealed two-stage chamber above the branch pipes, there is a magnet for the charge concentration on the metal rod. In the lower step of the smaller diameter of said chamber, there is a metal cup with a perforated bottom.

EFFECT: increased efficiency and reliability of evaluation by making it possible to integrally evaluate the effect of various materials on charge accumulation and due to approaching test conditions to the actual pumping conditions.
