Abstract
Systems and methods for pelletizing hot asphaltenes are provided. Asphaltenic hydrocarbons can be dispersed to provide two or more asphaltenic particles. The asphaltenic hydrocarbons can be at a temperature of from about 175° C. to about 430° C. The asphaltenic particles can be contacted with a film of cooling medium. The film can have a thickness of from about 1 mm to about 500 mm. At least a portion of the asphaltenic particles can be solidified by transferring heat from the asphaltenic particles to the cooling medium to provide solid asphaltenic particles. The solid asphaltenic particles can be separated from at least a portion of the cooling medium.
