Hydrotreating

Advanced process and catalyst systems to help optimize unit performance and maximize cycle length
Hydrotreating is an established refinery process for reducing sulphur, nitrogen and aromatics while enhancing cetane number, density and smoke point. Shell Global Solutions’ hydrotreating process combines advanced process technology, high-performance catalyst systems and efficient reactor internal designs. This technology has helped many refiners to rise to the clean fuels challenges facing their businesses; operators around the world have licensed new units for their grass-roots facilities. In addition, we apply new catalyst and reactor internals technology to revamp existing units, including upgrading for more complex duties such as dewaxing.
 
Drawing on the Shell Group’s (“Shell”) corporate heritage as the owner and operator of refining facilities, Shell Global Solutions’ technology is designed to operate reliably and efficiently, and to help maximise the return on investment throughout the life cycle of a unit. Our hydrotreating units incorporate Shell’s wide experience base as one of the largest operators of hydrotreating capacity in the world – Shell’s hydrotreating capacity represents 8% of the world’s capacity.
 
We have experience of a wide range of feedstocks and boiling ranges, including straight-run and cracked feedstocks, such as from fluidised catalytic cracking (FCC ), thermal conversion and coking, and boiling ranges from naphtha to FCC feedstocks.
 
We also have experience of helping refiners whose winter diesel has suboptimal cold-flow properties. In the past, this was addressed by kerosene blending or end-point reduction, which reduced the value or size of the refinery’s middle distillate pool. Shell’s distillate dewaxing catalyst can help to improve the diesel’s cloud point in a variety of process configurations.
