Investigation of electrostatic charge generation during benzene settling in tank trucks

Abstract This study investigates the electrostatic dissipation dynamics and sedimentation-induced electrification phenomena during the loading and resting processes of benzene tank trucks. Based on electrostatic dissipation equations and the mechanical equilibrium characteristics of impurity particle sedimentation in benzene media, we establish a computational model for liquid surface potential generated by particle sedimentation electrification in benzene storage tanks. The research reveals the correlation between tank electrostatic potential and dissipation time under variations of benzene medium parameters. These findings offer crucial engineering references for determining scientifically grounded resting durations and mitigating electrostatic accident risks in petrochemical transportation operations.
