Definitions
- Frac tionntion is preferably effected by distillation.
- Diluents e.g. low pour point hydrocarbons such as reservoir condensates, can be admixed with the slurry to improve the polyphosphates can be added to increase the waters ability to selectively adhere to the steel pipe and to displace any oil from the surface of the pipe without forming an emulsion.
- Scott et al. in U.S. 3,269,40l teaches facilitating flow of wax-bearing oil in a pipeline by dissolving in the oil, at superatmospheric pressure and while above its pour point, agas, B-gi N 00 flue gas, and hydrocarbons containing less than 3 carbon atoms.
- the gas becomes associated in some way with the wax crystals and prevents the precipitated wax from agglomerating to form strong wax structures.” Also, the gas collects on the surfaces of the wax particles-especially the larger ones-to form films of gas envelopes which isolate the particles from one another and prevents the wax particles from combining.
- solvent liquid cg. water
- the particles can be pumpability thereof.
- aportion e.g. up to 50% by carbon mixtures.
- the hydrocarbon e.g. crude oil, isfirst fractionated into at least two fractions, one fraction is congealed into spherical particles and then slurried with the other fraction'and the slurry transported preferably in a conduit.
- Kells in U.S. 271,080 separates wax from crude oils by pumping the crude oil, egg. in small streams or jets, into the bottom of a tank containing a brine at a temperature sufiiciently low to congeal the'wax. The congealed wax is recovered in the brine.
- Chilton et al. in U.S. 2,821,205 forms a film of water on the interior wall of the pipe to improve the pumpability of viscous oil.
- a light-petroleum or condensed casing-head gas can be mixed with the crude 'oil toreduce the viscosity.
- Agcnts such as phosphatesand above the scasonably ambient temperature of the transcoated with finely divided coating solids such as calcium' carbonate, etc. Watanabe teaches that it is known in the artto' disperse waxy particles by molding, prilling, spray drying,v extruding, etc. i Titus in US.

- Comminution is'accornplished by prilling, extruding, molding, shredding, grinding, andlike methods for dispersing or disintegrating the uncongealed or congealed material. Where-shredding or grinding is used, 'comminution preferably takes place .after-congelation. Congealing as used herein includes solidification,
- the high pour point fraction is preferably about'l to about 150 and more preferably about 10 to about 100 F. above its average con'gelation temperature as it'enters the congelation and comminution steps.
- Prilling can be accomplished by spraying the bottoms fraction, into a prilling tower where the prill comes in contact with gas (e.g.'air, N CO naturalgas, or like gases) and/or water.
- gas e.g.'air, N CO naturalgas, or like gases
- theprill is collected in a water bath at the bottom of the tower.
- Air is the preferred gas and is preferably moved through'the prilling tower, bynatural or forced convection, at velocities sufficient to not exceed the drop or settling rate.
- Temperature of the air, entering the prilling tower is preferably aboutl to about 230 and more preferably about 10 to about 150 below the congealing temperature of the prill.
- Temperature of theair leaving the prilling tower is preferably about 230. below to about 150 above and more preferablyabout below to about 10F. above .the average congealing temperature of the high pour point fraction entering the, prilling tower. Water is pref erably sprayed into the tower alongwith the air, the
- the water be sprayed into the tower in a direction normal to the airflow direction.
- Another method for dispersing the high pour point fraction isby extruding or spraying into water, the fraction preferablyat about 5 to about 100 F. and more preferably isv about to about 220? F. above its average 'congelation temperature.
- the water preferably flows countercurrent to the movement of the introduced high pour point fraction and more preferably the water is in'turbulent flow at the injection point of the high pour point fraction.
- the dispersed high pour pointfraction is lthereafter congealed, by admixing cooler water, e.g. at
- a surfactant can be incorporated into the high pour point fraction: before it is congealed, e.g'. it can be ad- 'mixed withthe fraction before or as it enters the prilling tower. Volume amountsof about 0.0001 to about 20% and preferably about 0.001 to about 10%, and more preferably about 0.01 to about 1% by volume, based on the fraction, are useful.
- the surfactant should have sulficieut oleophilic property to solubilize into or act like it is miscible with the fraction.
- surfactant molecules tend to orient their hydrophilic portion radially at thedroplet surface, Theoretically, this ghappensas the droplets of'wax are formed, imparting a more hydrophilic property to the droplet.
- Sorbitan monolaurate is an example of a useful surfactant.
- the surfactant is a petroleum sulfonate preferably having a monovalent cation, e.g.' Na+, and preferably having an-average equivalent weight of about 200 to about 600 and more preferably about 250 to about 500 and most preferably about 350to' about 420.

- temperatureof thelow pour point fraction during slurrying should be below and preferably at,least about 5 F.
- a liquid diluent such as straight] run gasoline, reservoir condensate,'-or like hydrocarbon, can be admixed with the low pour point fraction either before or after the: slurrying operation-any diluent which is miscible with the low pour pointfraction'and which preferably. has a pour ticles can be coatedwith a solid material. Such inhibits agglomeration of the particles and may permit higher slurry temperatures during transportation. Examples of coatings include those disclosed in US. 3,468,986 to Watanabe.
- the coating can be applied as a spray, either hydrous or anhydrous, or as an aqueous bath containing the solidmaterial.
- useful coating materials include inorganic and organic salts of the metals of Group II, III, IV-A, V, VI, VII, and VIII of the Periodic Table;

- EXAMPLE II overheads temperature of 500 F. at the end point and and other aluminum silicates, limestone, etc. Calcium carbonnie is a preferred coating material.
- a gas miscible with the low pour point fraction but preferably immiscible with the congealed fraction can be admixed with the slurry to reduce the viscosity thereof.
- the gas may be liquid at the temperature and pressure of the transportation system.
- miscible gases include CO lower hydrocarbons containing less than 4 carbon atoms, etc.
