FIELD: chemistry.
SUBSTANCE: damp gaseous chlorine is cooled then compressed. After that at first it undergoes three-stage separation with interstage cooling, then three-stage contacting with sulfuric acid The first two stages of contacting are carried out in two sequential contact reactors, between which chlorine is separated and cooled again The third stage is carried out in tray column.
EFFECT: decreasing of strong sulfuric acid consumption and simplification of process implementation
