ABSTRACT:
Methods and apparatus relate to treating fluid to at least reduce selenium content within the fluid, which may be an aqueous liquid and form a feed stream. The treating removes selenium that may be present in compounds, such as selenocyanate, from the feed stream based on adsorption from contact of the fluid with a sorbent. Flowing a gaseous hydrogen sulfide and sulfur dioxide containing stream over a support, such as activated carbon, may provide the sorbent impregnated with sulfur and utilized in the treating of the fluid.
