Separation of hydrogen sulfide and mercaptans from fluid streams
Patent
·
OSTI ID:5645635
A process for removing the HS radical from a stream of hydrocarbon gas, hydrocarbon liquid, or other fluid is described. The process includes the following steps: (1) electrolyzing a solution containing at least one halide selected from the group consisting of potassium iodide, potassium bromide, sodium iodide, sodium bromide, lithium iodude, and lithium bromide; (2) electrolytically converting at least some of the halide to a tri-halide in the solution; (3) contacting the fluid to be treated with the solution; (4) reacting the HS radical with the tri-halide in the solution in a manner forming elemental sulfur and the same halide originally electrolyzed; and (5) repeating all of these steps through a series of cycles of operation to progressively eliminate the HS radical.
