Abstract
A process for producing a distillable hydrocarbonaceous stream, fuel gases and blast furnace grade coke from a heavy, high sulfur, crude oil by producing delayed coke from at least a portion of the crude oil; crushing at least a portion of the coke to provide a finely divided coke feedstock to a briquetting operation where the finely divided coke is briquetted using crude oil or topped crude oil as a binder to produce briquettes of a size from about 3/4 inch to about 3 inches with the resulting briquettes being passed to a high temperature vertical calciner where the solids are desulfurized to produce a strong blast furnace grade coke. The distillable stream and fuel gas stream are recovered from the delayed coking operation, the vertical calciner and optionally a crude oil topping operation. In some instances coke particles in the size range from about 3/4 inch to about 3 inches may be passed directly to the calciner without crushing and briquetting. However, it is preferred to crush and briquette substantially all of the coke.
