Cyanamid studied the ability of existing refinery hydroprocessing units in the U.S. to produce ultra-low sulfur diesel fuel. A pilot plant study was conducted, focusing on two feedstocks and sets of operating conditions, one representing a severe West Coast operation on 100% light cycle oil and the other considered typical of a mid-Continent operation on a blend of straight-run distillate and LCO. Temperatures and space velocities required to achieve 0.05% product sulfur, while still staying within typical constraints of total unit pressure and hydrogen treat gas rates, have been determined. From these initial activity results, effects on catalyst cycle life and barrels per day of diesel fuel produced have been estimated. It is concluded that most existing middle distillate hydroprocessing units can achieve 0.05% sulfur diesel fuel, but only at considerably higher operating temperatures and/or lower space velocities. These more severe conditions will result in significantly higher refinery operating costs and/or required new capital investment. Some supply shortages could occur if the timetable to meet these new regulations is unrealistically tight. Although considerable API gravity improvement and polynuclear aromatics saturation can be achieved, most existing hydroprocessing units are not capable of any significant reduction in total aromatics.
