Hazard assessment of high speed slurry blending using computer modelling of electric fields and potentials

[摘要] Generalised published guidelines indicated a new high shear slurry dispersion system should include inerting of the vessel headspace to avoid electrostatic ignition hazards. This paper describes how computer modelling of electric fields and potentials, combined with experimental measurements on laboratory scale equipment, was used to show that inerting is not warranted in this case. Ultimately the conclusion was that, subject to certain restrictions, an incendive electrostatic discharge in the new blender could be considered so unlikely that inerting or other protective measures would not be required.
