Sulphur deposition on the internal wall of a pipeline is caused by the temperature effect on the solubility of sulphur in the carrier fluid and is not due to particulate sulphur present. Deposition can be completely eliminated by proper insulation of the pipeline to prevent "c8ld-spots" and the resultant temperature gradient necessary for sulphur to precipitate from solution. Friction head losses for sulphur-condensate slurry systems are quite acceptable from a technical and economic standpoint and, in fact, are less than many present commercial slurry systems. Slurry transportation of sulphur in a hydrocarbon pipeline is a viable possibility and promises to have economic advantage over currently accepted transportation modes.
