Q & A > Question Details
How many Vacuum Residue Hydrocrackings are in operation worldwide?
What is the maximum conversion achievable (ie minimum bottom product after the atmospheric and vacuum distillation of the reactor effluents) in these plants?

At last count, there were more than 18 commercial units operating in the world today. Conversions range from 65 to 90% of the vacuum residue depending on the outlet for the unconverted residue (i.e. routed to fuel oil, to a delayed coker, to a boiler for steam and power, to a gasification unit, etc.).

Two refineries are going ahead for this Vacuum Residue slurry hydrocracking of Chevron Lummus Technology. Since hydrocracking product yield will be more stable, saturated , better removal of heteroatoms when compared to Delayed coking process products . When compared to VGO Hydrocracker the yield of light distillates and middle distillates may be less.

The ebulated bed resid hydrocracking licensors will provide you with their latest counts of numbers of units in operation as well as attainable conversion for different crudes. There was one fixed bed unit operating in South Africa, but is probably no longer in service.
