1. A method for separating at least one sulfur-containing compound from a hydrocarbon-based fuel, the method comprising:
introducing a pressurized and heated parent stream comprising a mixture of the at least one sulfur-containing compound and the hydrocarbon-based fuel into a first vortex tube at a tangential inlet, the first vortex tube comprising an axial primary outlet at an inlet end and a secondary outlet at an opposing end; withdrawing a predominantly vapor primary stream from the primary outlet, the primary stream comprising a lower concentration of the at least one sulfur-containing compound than the parent stream; and removing a predominantly liquid secondary stream from the secondary outlet, the secondary stream comprising a higher concentration of the at least one sulfur-containing compound than the parent stream.
