<p>Heavy crude oil 12 is mixed with a diluent 18 prior to distillation to produce gaseous hydrocarbon products, overhead liquid hydrocarbons (from which recycle diluent 16, suitably boiling in the range 150-800 DEG F, is recovered) and residuum 60, suitable for delayed coking at 66 and 68 to produce metallurgical coke. The mixture of crude oil and diluent can be subjected to dehydration at 22 and desalting at 24 and 26 prior to distillation. <IMAGE></p> |
