| Abstract | Of the eight techniques, only 1 and 2 are commonly practiced, and 3 and 4 are employed in some operations. All the other schemes are not practiced as they are expensive and/or unproven at the commercial scale. The first technology has a major drawback as it produces a corrosive chlorine solution, and the purge water stream needs to be treated. In addition, there is always some chlorine escaping from the process, creating environmental issues. The second technology emits carbon tetrachloride along with the absorber tail gas, which is environmentally unacceptable. Thus, at present, no viable technology is available to recover chlorine, and new plants are often designing the process to neutralize chlorine from the tail gas with caustic and dispose off the eff luent. |
