1. The removal of impurities from a metal by electrolysis.
2. A petroleum refining procedure to aid in separating chemical treating agents from the hydrocarbon phase by use of an electrostatic field.
3. In chemical engineering, a petroleum refinery process for light hydrocarbon streams in which an electrostatic field is used to assist in separation of chemical treating agents (acid, caustic, doctor) from the hydrocarbon phase.
4. A method of metal refining in which the metal is dissolved anodically (positive electrode) and plated at the cathode (negative electrode) of an electrolytic cell.
