  • Method for recovering hydrogen bromide gas
    Patent number: 4119413
    Abstract: This invention relates to a method for recovering hydrogen bromide gas from a gaseous stream. The method comprises contacting the gaseous stream with a nonaqeous hydrogen bromide absorbent containing acetic acid to absorb at least a portion of the hydrogen bromide. The hydrogen bromide containing absorbent is then heated to desorb at least a portion of the hydrogen bromide.
