Large scale chemical plants: eliminating the electrostatic hazards

This paper discusses a novel approach to avoiding electrostatic hazards ari sing from the treatment of effluent in a fine chemicals manufacturing site. Whilst methods of avoiding electrostatic hazards for small vessels and pum ping small quantities through pipes are simple, the approach for orders of magnitude increases in scale found in treatment plants required novel metho ds which were solved by the application of both basic physics and chemical engineering methods.
