Claim 0:
1. A method of production for consistently sized and shaped petroleum coke from vacuum residue, the method comprising the steps of:
fractionating vacuum residue in a coker fractionator, where the vacuum residue is produced in a vacuum distillation column at a temperature between about 430° C. to about 450° C. and a pressure of about 0.1 kPa, where fractionating the vacuum residue removes liquid propane gas, fuel gas, coker naphtha, light coker gas oil, and heavy coker gas oil to produce a processed vacuum reside, where the coker fractionator operates at a pressure between 1 psig to 50 psig and a temperature in a fractionator flash zone between 650° F. and 950° F.;
supplying the processed vacuum residue to an extruder;
heating the processed vacuum residue throughout a horizontal profile of the extruder from an inlet to an outlet of the extruder, wherein a temperature along the horizontal profile is between about 350° C. and about 450° C. and a pressure along the horizontal profile is 0.1 kPa and is consistent;
venting hydrocarbon off-gases from the extruder along the horizontal profile of the extruder from the inlet to the outlet of the extruder; and
recycling the hydrocarbon off-gases to the coker fractionator; and
cutting consistently sized and shaped petroleum coke at the outlet of the extruder comprises the use of an automatically timed blade to cut the consistently sized and shaped petroleum coke.
