Patent ID: 8591743

Claim:
A method of extracting iodine from a fluid stream, comprising: providing a portable system to a first location, the portable system comprising a mobile platform, a treatment unit capable of oxidizing iodine ions in a solution into elemental iodine, and a first adsorption unit capable of adsorbing iodine; wherein the treatment unit is an in-line mixing apparatus comprising: a cylindrical outer tube comprising a sidewall, a closed end, an open end opposite the closed end, a first opening in the open end, and a second opening in the sidewall adjacent the open end; a cylindrical inner tube comprising an inlet end, a closed end, and a sidewall, the sidewall having openings therein, the inner tube being located coaxially inside the outer tube and having a cross-sectional area, and the inlet end of the inner tube being adjacent to the open end of the outer tube; wherein the outer tube closed end is adjacent the inner tube closed end, the outer tube closed end and the inner tube closed end being separated by a longitudinal gap so that the inner tube closed end does not contact the outer tube closed end; a first feed tube connected to the inlet end of the inner tube and passing though the second opening, the first feed tube receiving the fluid stream; and an exit tube for the fluid stream connected to the first opening in the outer tube; wherein the first location provides at least one fluid stream containing iodine; separating the iodine from unwanted material in the at least one fluid stream by passing the at least one fluid stream through a separator; passing the at least one fluid stream through the treatment unit, and the first adsorption unit to accumulate the iodine in the first adsorption unit, the at least one fluid stream entering the in-line mixing apparatus through the first feed tube and exiting the in-line mixing apparatus through the exit tube; transporting the first adsorption unit to a second location; and extracting the iodine from the first adsorption unit at the second location.
