Abstract
W/O and O/W microemulsions have been evaluated as emulsifiers for the treatment of oil spills, both in laboratory and in a marine simulator. Two systems have been used: sea water-decane-1-pentanol-sodium dodecylsulfate, and sea-water-Arabian Light crude oil-1-pentanol-sodium dodecylsulfate. Their equilibrium diagrams have been determined. They showed zones of 2, 3, and even 4 liquid-phases in equilibrium. the efficiency of these emulsion mixtures has been tested in a marine simulator designed according to the MIL-E 22864 Navy Norm. Mixtures as W/O micro-emulsions showed greater efficiency than O/W microemulsions. For a given mixture the optimum surfactant-to-cosurfactant ratio was that corresponding to composition in the transition zone from W/O to O/W microemulsions, as the equilibrium diagrams indicated.
