A VISCOUS LIQUID OR A SLURRY IS TRANSPORTED THOUGH A CONDUIT UNDER PRESSURE

A viscous liquid or a slurry is transported through a conduit under pressure by absorbing in the material an inert immiscible fluid which has a vapor pressure greater than the liquid or the slurry and is in a gas phase under the conditions in the conduit. This reduces the apparent viscosity of the material. Sufficient pressure is maintained in the conduit to prevent the formation of free gas. The method is useful for transporting a viscous hydrocarbon or a phosphate slime-water slurry through a pipeline; the fluid may be natural gas.
