COLUMN FOR SORPTION OF IODINE FROM SOLUTIONS Russian patent published in 2004 - IPC

FIELD: mass-exchange apparatus; sorption columns; extraction of iodine from low-concentrated solutions, for example formation water.

SUBSTANCE: proposed column includes cylindrical housing divided into three independent chambers by two solid partitions; arranged in these chambers are bearing checkers with ionite. For compacting the ionite, sealing checkers provided with weights in form of rings are placed over each layer. Column is provided with collector with valves for independent delivery of iodine-containing solution under each bearing checker and discharge of solution from upper portion of chambers; column is also provided with collector for independent delivery of alkali and flushing water under each bearing checker and discharge of desorbate and flushing water from upper portion of chambers. Use of compacted layer of ionite improves mass-exchange characteristics of column. Use of three independent chambers enhances efficiency of process due to saturation of ionite of each layer with iodine.

EFFECT: enhanced efficiency.
