<p>Crude oils containing at least 25% wax are transported by fractionating (e.g., by distillation) the crude oil into at least a relatively high pour point fraction, a relatively medium pour point fraction and a relatively low pour point fraction. The medium pour point fraction is congealed (preferably by prilling), and slurried in a mixture of the relatively low pour point fraction and a portion of the high pour point fraction. The remaining high pour point fraction can be congealed with the medium pour point fraction. Diluents, e.g., crude oil, can be added to improve pumpability. This procedure reduces the formation of strong wax matrixes and creates a slurry with better pumpability characteristics.</p> |
