ABSTRACT:
A continuous process for the extraction of bromine from a bromine-rich brine in high efficiency while dramatically reducing the steam requirement for the distillation by operating a contact tower under vacuum. The contact tower is designed to operate near the boiling point of the feed brine so that only stripping steam is needed to remove elemental bromine from the brine.
