Study on a Novel Excitation Coil Used in Electromagnetic Anti-Wax Apparatus

Abstract:

The deposition of paraffin wax during the pipeline transportation impedes the flow of crude oil and eventually blocks the pipelines. In recent years, electromagnetic paraffin control technology was increasingly utilized as an alternative energy-saving method. However, the efficiency of magnetic paraffin control is restrained by edge effects in conventional anti-wax apparatus. So, theoretical and experimental researches on novel anti-wax apparatus with step solenoid have been performed to improve the efficiency of paraffin control. The effect of geometric structure on field distribution was investigated to optimize the coil structure using finite element simulations. The effective correction of the edge effect of conventional solenoid field and the elimination of novel edge effect induced by the step field manifest the superiority of multi-step coil structure in paraffin control. Therefore, a novel apparatus with positively multi-step structure in the outlet of the excitation solenoid and negatively multi-step structure in the inlet was presented.
