METHOD FOR NON-DESTRUCTIVE CONTROL OF PARAFFIN CONCENTRATION IN OIL FLOW BASED ON RADIOISOTOPIC RADIATION Russian patent published in 2021 - IPC G01N23/02 

FIELD: measurement equipment.

SUBSTANCE: invention relates to measuring equipment and namely to radioisotope devices for non-contact measurement of the concentration of suspended asphalt-resin-paraffins in the oil flow in the pipeline with the determination of the change in the intensity of the flow of ionizing radiation when it passes through the controlled substance. The invention can be used in the field of operation of pipeline transport, systems for the collection and treatment of oil, gas and water at the enterprises of the oil and gas industry at oil enterprises that transport hydrocarbons. The present method based on the effect of photoelectron absorption of a narrowly collimated beam of gamma radiation allows to measure the concentration of asphalt-resin-paraffin compounds with high accuracy (the relative error in determining the percentage of paraffin from the total volume of the oil-paraffin mixture does not exceed 1%) by a non-contact method (the sensitive element is not introduced into the moving measuring medium) to measure the concentration of asphalt-resin-paraffin compounds in the solid phase in a moving oil stream, and also differs in speed, measurement continuity and adaptability of the results to the temperature conditions of the environment, which are the main factor in the release of wax from the oil flow, which thereby increases the reliability of the measurement results.

EFFECT: invention is aimed at improving accuracy of determining the concentration of suspended asphalt-resin-paraffins in the oil flow in the pipeline during the transportation of hydrocarbons.
