Separation of light gases from halogens

A process for separating light gas(es) from a halogen, comprising:

• (a) providing a feed of a halogen and one or more light gas(es) to a distillation column or flash vaporizer;
• (b) operating the distillation column or flash vaporizer to separate the feed into (i) a first liquid containing a major amount of the halogen and no more than a minor amount of the light gas(es), and (ii) a first vapor containing a major amount of the light gas(es) and no more than a minor amount of the halogen;
• and
• (c) providing the first vapor to a chemical scrubber comprising a solid halogen scavenger to recover the halogen from the vapor, wherein the halogen scavenger sorbs the halogen through a chemical reaction with the halogen.

A process for separating light gas(es) from a halogen, comprising:

• (a) providing a feed of a halogen and one or more light gas(es) to a distillation column or flash vaporizer, wherein the light gas(es) comprise a C1-C4 hydrocarbon;
• (b) operating the distillation column or flash vaporizer to separate the feed into (i) a first liquid containing a major amount of the halogen and no more than a minor amount of the light gas(es), and (ii) a first vapor containing a major amount of light gas(es) and no more than a minor amount of halogen;
• and
• (c) providing the first vapor to a chemical scrubber comprising a solid halogen scavenger to recover the halogen from the first vapor, wherein the halogen scavenger sorbs the halogen through a chemical reaction with the halogen.
