Chlorine separation and purification

Will the chlorine gas produced at the anode in chlor-alkali process dissolve in saturated salt water? How is chlorine separated from saltwater? Does the anode part keep cycling? Could some expert please provide an answer? Thank you
Will the chlorine gas produced at the anode in chlor-alkali process dissolve in saturated salt water? Chlorine has a certain solubility in saltwater; the brackish water in the anode cell contains about 0.5–1 g/l of chlorine. How is chlorine separated from saltwater? ... The anode solution is partially recirculated, and partially sent to the vacuum dechlorination process in the brackish water dechlorination unit. Desalination by brine removal after dechlorination or MVR concentration
Will the chlorine gas produced at the anode in chlor-alkali process dissolve in saturated salt water? -----Yes, how is chlorine separated from saltwater? ---After electrolysis, is the gas-liquid separation and the anode section continuously recycled? ----Yes

Will the chlorine gas produced at the anode in chlor-alkali process dissolve in saturated salt water? How is chlorine separated from saltwater? Does the anode part keep cycling? The chlorine gas generated at the anode in the electrolyzer dissolves in the saltwater. Since sodium ions in the saltwater pass through the ion exchange membrane into the cathode chamber, the concentration of the saltwater remains unsaturated; the concentration of the saltwater at the outlet of the ion exchange membrane electrolyzer is around 200 g/L. The chlorine gas produced by the electrolyzer, along with the brine, flows out through the outlet hose of the unit cell. At the gas-liquid separator located in the main outlet pipe of the electrolyzer, separation takes place: the gaseous chlorine enters the chlorine main pipe, while most of the liquid phase goes into the dechlorination tower, where the chlorine dissolved in the brine is removed. The brine is then reprocessed to increase its concentration, and a small portion of this brine together with the purified brine is mixed again and fed into the anode of the electrolyzer for electrolysis.
Thank you, it’s very detailed:lol
The anode solution is not circulated; the small amount of brackish water that returns is used to provide oxidizing power through dissolved chlorine, in order to protect the titanium tubes； Catholyte circulation.
