Selective separation and recovery of chlorine from gas mixtures |
摘要 |
A process for separating chlorine of high purity from a chlorine-containing feed gas by absorption of the chlorine using an inert absorbent and downstream desorption of the chlorine from the absorbent/chlorine mixture drawn off from the absorption stage by the supply of mixture to a desorption distillation column which is coupled to a chlorine separation column in such a way that the top of the chlorine separation column and an upper section of the desorption distillation column and a lower section of the desorption distillation column and the bottom of the chlorine separation column are connected to one another on both the gas and the liquid side, the absorbent/chlorine mixture being supplied exclusively to the desorption distillation column, and high-purity chlorine being drawn off from a middle region of the chlorine separation column.
