Abstract (en)
[origin: US2008233027A1] Processes comprising: providing a gas stream comprising chlorine and at least one secondary component selected from the group consisting of carbon dioxide, nitrogen and oxygen; pressurizing the gas stream in a first stage to an elevated or enhanced pressure, preferably at least about 10 bar; cooling the pressurized gas stream in a second stage comprising a condensation zone and a gas/liquid contact zone disposed below the condensation zone, such that at least a portion of the chlorine is condensed and contacted countercurrently in the gas/liquid contact zone with the pressurized gas stream entering the second stage to form a condensate; and separating the condensate in a third stage comprising a rectifying column to provide a chlorine-rich sump stream and a low-chlorine head stream.
