Abstract: | Separation of crude oil from oil-in-water emulsions in a square batch electrocoagulation cell, using an aluminum screen as the sacrificial anode was studied, the cathode was a rectangular aluminum plate placed on the cell bottom below the anode. The oil separation efficiency was insensitive to the sodium chloride electrolyte concentration. Increasing current density increased the rate of oil separation from the emulsion. Also it was found that increasing the number of screens per stack at the same current intensity, does not affect the efficiency of oil separation. The removal doesn't depend on the initial pH in the range of pH ~3?8. |
