Abstract
The present invention is directed to a process for the removal of elemental sulfur from fluids such as fuels, e.g. gasoline, kerosene, diesel or jet, by contacting said fluids with an immiscible treatment solution comprising water or immiscible alcohol, caustic, sulfide or hydrosulfide and optionally mercaptan, in a staged co-current mixer under conditions such that the immiscible treatment solution constitutes the continuous phase.
