Discrete element method modeling of the triboelectric charging of polyethelene particles: Can particle size distribution and segregation reduce the charging?

Original language description

Polyethylene particles of various sizes are present in industrial gas-dispersion reactors and downstream processing units. The contact of the particles with a device wall as well as the mutual particle collisions cause electrons on the particle surface to redistribute in the system. The undesirable triboelectric charging results in several operational problems and safety risks in industrial systems, for example in the fluidized-bed polymerization reactor. We studied the charging of polyethylene particles caused by the particle-particle interactions in gas. Our model employs the Discrete Element Method (DEM) describing the particle dynamics and incorporates the 'Trapped Electron Approach' as the physical basis for the considered charging mechanism. Themodel predicts the particle charge distribution for systems with various particle size distributions and various levels of segregation. Simulation results are in a qualitative agreement with experimental observations of similar particulat
