Integrated process to produce asphalt, petroleum green coke, and liquid and gas coking unit products

摘要

An integrated process is provided to produce asphalt, high quality petroleum green coke, and liquid and gas coker unit products. Sulfur molecules contained in heavy petroleum fractions, including organosulfur molecules, and in certain embodiments organonitrogen molecules are oxidized. The polar oxidized sulfur compounds shift from the oil phase to the asphalt phase. The deasphalted/desulfurized oil phase is passed to a coker unit to produce liquid and gas coker products as an effluent stream and recover high quality petroleum green coke.
