<p>1421802 Transporting hydrocarbon oils MARATHON OIL CO 24 Aug 1973 [18 Sept 1972] 40229/73 Addition to 1421803 Heading C5E A process for converting hydrocarbon mixtures into a slurry which is transportable in pipelines and tanks comprises (1) fractionating the mixture into a relatively low pour point fraction and a relatively high pour point fraction; (2) introducing the relatively high pour point fraction into the bottom of a tower through which a continuous stream of water, which enters the top portion of the tower at at least 5‹ F. below the congelation temperature of the relatively high pour point fraction, flows in countercurrent; (3) imparting sufficient turbulence to the high pour point fraction to disperse it in the water within the tower and maintaining contact between the disperse particles and the water to congeal the particles; (4) introducing the relatively low pour point fraction into the top of the tower to form an interface on top of the water in the tower and permitting the congealed particles to rise to this interface; and (5) withdrawing a slurry of congealed particles in the low pour point fraction from the tower. Fig. 2 (not shown) illustrates a process in which the relatively high pour point fraction is dispersed in hot water and the mixture introduced into the bottom of the tower.</p> |
