Abstract
Process for the recovery of chlorine from chlorine-containing gas mixtures in a multi-stream heat exchanger wherein the chlorine-containing mixtures are separated from other gases which would solidify or liquify in the process, either before or after compression of the mixture, and is then cooled below the dew-point of chlorine in one stream of the heat exchanger; the liquid and gaseous phases thus produced are then separated and re-passed separately through the heat exchanger, the chlorine passing to recovery and the gas phase to re-cooling before being re-passed once more through the heat exchanger prior to discharge and wherein a predetermined mixture of gaseous and liquid phases is also recycled separately through the heat exchanger before re-compression and return via the heat exchanger to the phase-separation apparatus.
