The general object of this invention is to provide an improved process for sweetening and desulfurizing sulfur-containing crude oil streams. Heating the sulfur-containing crude oil stream to an elevated temperature for an extended period of time while stirring and bubbling an inert gas into the crude accelerates the removal of sulfur containing gases from the crude oil stream. Furthermore, the addition of a polyalkylamine to the stirred crude oil can also greatly assist in the expulsion of sulfur containing gases. After processing under these conditions, the hydrogen sulfide producing capacity of the crude oil is reduced significantly, thus making the crude safer for transportation and handling by reducing the health and environmental risks.

1. A process for removing sulfur from crude petroleum, comprising:(a) heating the crude petroleum to a temperature of at least about 300.degree. F. (149.degree. C.); (b) maintaining said temperature for a holding period; (c) stirring the crude petroleum during the holding period; and (d) bubbling a substantially inert gas through the crude petroleum during the holding period, thereby generating an exhaust gas containing sulfur compounds.
