A microelectrophoretic technique was used with the aid of a polarizing microscope to investigate the separation of solid hydrocarbons from a residual raffinate in different types of solvents in an electric field. The time required for electroseparation of the slurries was determined mainly by solvent viscosity. The solvents tested included n-heptane, BR-1 naphtha, toluene, methyl ethyl ketone, and a methyl ethyl ketone-toluene mixture. The effects of charge on hydrocarbon precipitation yields on the electrodes were assessed. The precipitation of solid hydrocarbons from deresined raffinate proceeded through a stage of interelectrode circulation which indicated an unstable charge of the disperse phase.
