Abstract: A process for removing hydrogen sulfide out of liquid sulfur is provided by passing liquid sulfur and saturated steam through at least one acceleration nozzle within a container maintained at less than atmospheric pressure. The saturated steam and liquid sulfur discharged from the acceleration nozzles converge at a common point outside the acceleration nozzle and collide against an impact target so that hydrogen sulfide is removed out of the liquid sulfur. Two acceleration nozzles may be used positioned on a common plane with the outlets of the nozzles facing each other. The discharged steam adiabatically expands within the container which causes the discharged streams to accelerate and which also causes the temperature of the liquid sulfur drop.
