SULFUR IS TRANSPORTED THROUGH A PIPELINE

Sulfur is transported through a pipeline by injecting molten sulfur under pressure into a liquid petroleum carrier which is more viscous than liquefied petroleum gas and contains a small amount of a C5 or lower volatilizable hydrocarbon to form a slurry containing at least 10% by vol of sulfur, partially evaporating the hydrocarbon to cool the slurry and concentrate it to a sulfur content of at least 15% by wt, flashing off the remainder of the lower hydrocarbon to cool the slurry by evaporation and concentrate it further to a sulfur content above 20% by wt, and injecting the thickened and cooled slurry into a pipeline. The carrier may be a petroleum distillate or condensate or crude oil containing a small amount of a naturally present surfactant.
