ABSTRACT:
Heavy high-sulfur crude oil is subjected to distillation to produce gas and liquid hydrocarbon products and a residuum. The gas and liquid products are desulfurized. Part of the residuum is coked in a delayed coker, and sulfur in the coke is removed by high temperature calcination. The remainder of the residuum is air-blown to produce an asphalt product, and sulfur recovered from the other products is added to the asphalt to produce a sulfur-enriched asphalt product.
