Abstract
A process includes supplying a bromide brine and removing organic compounds from the bromide brine. The method also includes acidifying the bromide brine to form a stream containing hydrobromic acid and separating the hydrobromic acid from the stream containing hydrobromic acid.
Claims18
A process comprising:
- supplying a bromide brine;
- removing an organic compound from the bromide brine by:
- adjusting the pH of the bromide brine to phase separate organic compounds;
- and
- removing the phase separated organic compounds from the bromide brine;
- acidifying the bromide brine to form a stream containing hydrobromic acid;
- separating the hydrobromic acid from the stream containing hydrobromic acid;
- acidifying with an acid the bromide brine to form hydrobromic acid;
- and
- separating the hydrobromic acid from other species with higher and lower volatility through distillation after the step of acidifying the bromide brine to form hydrobromic acid, wherein the step of separating the hydrobromic acid includes forming the following streams:
- 1) volatile organic compounds or organic compounds that distill with steam;
- 2) water;
- 3) a water containing hydrochloric acid;
- and
- 4) hydrobromic acid.
