Abstract
Disclosed is a method of removing chlorine from a mixture of gases. The mixture of gases is contacted with a liquid which contains a compound having the general formula ##STR1## where n is 1 to 3, whereby chlorine in the mixture of gases is absorbed by the liquid. The liquid is then heated to volatilize the chlorine and separate it from the liquid.
Claims13
A method of removing chlorine from a mixture of gases comprising
- (a) contacting said mixture of gases with a liquid which comprises a compound having the general formula ##STR3## where n is 1 to 3, whereby chlorine in said mixture of gases is absorbed by said liquid;
- and
- (b) heating said liquid to volatilize said chlorine therefrom and separate said chlorine from said liquid.
A method of removing chlorine from a mixture of gases containing about 1 to about 45 wt % chlorine comprising
- (a) passing said mixture of gases up through a column of inert material;
- (b) passing down through said column a liquid which comprises a compound having the general formula ##STR4## where n is 1 to 3, whereby chlorine in said mixture is absorbed by said liquid;
- (c) heating said liquid to its boiling point to volatilize chlorine therefrom;
- and
- (d) recycling said liquid to said column.
