✦ Synopsis

Stubborn emulsions of distilled and artificial sea water in mixtures of Navy Special Fuel Oil (NSF01 and Navy Distillate (ND) have been broken by applying several approaches suggested by Lawrence some years ago. The effect of NSF0 content, demulsifying agent structure and concentration, polymer concentration and salt concentration on the demulsifying process was studied. It was found that a commonly-used wetting agent, sodium di-2-ethylhexyl sulphosuccinate, was a particularly potent demulsifier and apparently superior to several commercial demulsifiers. The addition of a water-soluble polymer of high molecular weight intensified demulsifier action, while that of small quantities of an alkaline salt promoted separation in the most difficult cases, particularly those involving distilled water as the discontinuous phase.
