• after the degassing and dewatering the crude oil stream, delivering the crude oil stream into a crude oil delivery conduit system, the crude oil delivery conduit system having a crude oil conduit delivery system inlet and a crude oil conduit delivery system outlet, at least one fluid mixing mechanism positioned in the crude oil delivery conduit system, and at least one crude oil treatment composition delivery inlet, the crude oil conduit delivery inlet positioned between the inlet of the crude oil delivery conduit system and the at least one fluid mixing mechanism;
• and
• delivering a metered volume of a treatment composition through the crude oil treatment composition inlet into contact with the crude oil stream transiting the crude oil delivery system;
• wherein the crude oil transiting the crude oil delivery system upstream of the mixing mechanism comprises crude oil, between 1000 and 400,000 ppm sulfide content, an inorganic strong base component and at least one polar aprotic solvent,
• and wherein the crude oil transiting the crude oil delivery system at a location downstream of the mixing mechanism comprises crude oil, less than 1000 ppm sulfide content and at least one inorganic sulfate.
