REMOVAL OF ASPHALT-RESIN-PARAFFIN DEPOSITS IN OIL PIPELINES USING A MOVING ULTRA-HIGH-FREQUENCY ELECTROMAGNETIC RADIATION SOURCE

Abstract

The formation of asphalt, resin, and paraffin deposits (ARPD) in oil pipelines is a key issue in the modern oil production and transportation industries. This paper proposes an innovative approach to removing ARPD using a moving source of high-frequency electromagnetic radiation based on the principle of dielectric heating. The study demonstrates that electromagnetic radiation in the 900-2450 MHz frequency range enables highly efficient volumetric heating of deposits, achieving localized temperature increases of 60-150°C. A mathematical model for electromagnetic wave propagation in the coaxial structure of an oil pipeline is proposed, an antenna system is designed, and numerical simulation of the temperature field is conducted.
