Thompson, W H; Young, E E

A process is described for removing elemental sulfur particles from sulfur contaminated petroleum oils used in preparation of sulfur-oil slurries for pipeline transportation. The sulfur and oil are separated into their component parts at the terminal end of the line and each component is purified. The method of purifying elemental sulfur-contaminated oil separated and recovered from sulfur-oil slurries consists of contacting the contaminated oils with an aqueous solution containing polysulfide forming compounds and preferably ammonium polysulfide forming compounds, the solution having a pH above 7.
