Abstract:
A method for removing hydrogen sulfide out of liquid sulfur, comprising the steps:providing at least one acceleration nozzle equipped with an inlet extension and an outer chamber that surrounds the inlet extension within a container maintained at less than atmospheric pressure;passing hydrogen sulfide contaminated liquid sulfur through the inlet extension in at least one acceleration nozzle and passing saturated steam through an outer chamber that surrounds the inlet extension;discharging the saturated steam and liquid sulfur from the acceleration nozzle so that the streams of saturated steam and liquid sulfur converge at a common point outside the acceleration nozzle and the streams of saturated steam and liquid sulfur collide against an impact target so that hydrogen sulfide is removed from the liquid sulfur;removing the hydrogen sulfide out of the container via a vacuum, andremoving the hydrogen sulfide-diminished liquid sulfur out of the container, wherein 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.
