  • Patent number: 4220505
    Abstract: A liquid solution containing a tri-halide from the halogen group consisting of bromine and iodine is passed in countercurrent flow with fluids containing sulfur compounds, including hydrogen sulfide, within a tower. The tri-halide solution removes selected sulfur compounds, including hydrogen sulfide, from the fluids and the halide solution is drained from the bottom of a tower for sulfur removal, electrolytic regeneration, and hydrogen release in order that a tri-halide from the electrolytic cell may be returned to the tower for continual removal of sulfur compounds, including hydrogen sulfide. A portion of the spent halide solution from the bottom of the tower is conducted to a point in the tower above the introduction of the tri-halide solution to prevent the loss of the diatomic halogen.
