PROCESS FOR REMOVING ELEMENTAL SULFUR FROM FLUIDS

摘要

A process for removing elemental sulfur from fluids such as refined petroleum products transported through pipelines for the transportation of sour hydrocarbon streams. The fluids are contacted with an aqueous solution containing caustic, an aliphatic mercaptan and optionally a sulfide to produce an aqueous layer containing metal polysulfides and a clear fluid layer having a reduced elemental sulfur level.
