    Abstract: A waste gas exhausted from a chlorination furnace during the manufacture of titanium tetrachloride or zirconium tetrachloride which contains larger quantities of CO.sub.2 and harmful substances such as chlorides and the like is subjected to treatment which comprises the sequential steps of scrubbing the waste gas in a water scrubbing column, removing moisture from the waste gas to allow the waste gas to have a dew point of no more that 5.degree. C., and adsorbing the waste gas in an activated carbon packed column. The process is capable of reducing the content of chlorides in the waste gas to a level of no more than 5 ppm in HCl equivalent.
