The charges acquired by polyethylene and glass particles fluidized by argon, nitrogen, and air at different humidity levels in acrylic and steel columns have been measured. Increased bed expansion at higher fluidization gas velocities lowered the space charge effect, allowing the particles to acquire more charges. The low dielectric strength of argon limits the extent of charging when the particles...
