Numerical Modeling of Heavy Hydrocarbon Liquid Heating

Abstract

-The results of two-dimensional mathematical modeling of heat and mass transfer in a highly viscous hydrocarbon liquid by inductive and radio-frequency (RF) electromagnetic (EM) heating are presented. The model takes into account the dependence of the liquid's viscosity and thermal conductivity on the temperature and also the presence of thermal convection effects. It is shown that the occurrence of volumetric heat sources inside the liquid caused by EM radiation yields an intensive deep heating as compared with inductive heating. Numerical calculations show that, in both these cases, the single vortex flow structure is formed in the whole volume of the liquid. However, RF EM heating provides a more homogeneous distribution of heat in the medium and requires three-fold less power consumption in comparison with induction heating.

Temperature Field in a Material Containing Asphalt-Resin-Paraffin Substances in a Microwave Electromagnetic Field

“…The features of propagation of such a wave within a waveguide with electrical losses and phase transitions of the media filling the waveguide are not presented in the literature. The studies of the electromagnetic fields application intended for solving oil and gas production problems have been evolving in recent years in the trends highlighted in the papers [15][16][17][18][19][20]. A numerical study of the paraffin plugs heating and melting process in the oil pipelines equipment via microwave electromagnetic radiation generated by a super-high-frequency electromagnetic wave of the H11 type is simulated and conducted in this paper.…”
