    Abstract: High purity Cl2 is separated from an inlet gas (1) by absorption (C1) and subsequent desorption in a distillation column (C2). The upper part of the distillation column is coupled with the top of a chlorine separation column (C3) and the lower part of the distillation column (C2) is coupled to the sump of the chlorine separation column (C3). The mixture (3) of absorption material and Cl2 is passed into the distillation column and high purity Cl2 (6) is drawn off from the central region of the chlorine separation column. Also claimed is the process for separating high purity Cl2 from a gas stream by subjecting it to pressure swing adsorption then compressing the gas to 5-10 bar and finally releasing the Cl2 by low temp. distillation as the sump product of the distillation column. The head product is returned to the inlet stream.
