Processes and systems for drying liquid bromine utilizing two fractionators to produce a substantially dry liquid bromine stream and a substantially bromine-free water stream. Wet bromine liquid may be conveyed to a first fractionator wherein a substantially dry bromine liquid is produced, while a vapor stream from the first fractionator may be condensed into a first liquid phase comprising bromine saturated with water and a second liquid phase comprising water saturated with bromine. The water saturated with bromine may be conveyed to a second fractionator to produce at least substantially bromine-free water.
1. A process comprising: fractionating a wet bromine liquid in a first fractionator at conditions to produce at least a substantially dry bromine liquid and a first stream of bromine vapor and water vapor;condensing the first stream of bromine vapor and water vapor to form at least a first liquid ph
1. A process comprising: fractionating a wet bromine liquid in a first fractionator at conditions to produce at least a substantially dry bromine liquid and a first stream of bromine vapor and water vapor;condensing the first stream of bromine vapor and water vapor to form at least a first liquid phase comprising bromine saturated with water and a second liquid phase comprising water saturated with bromine;separating the first liquid phase and the second liquid phase;fractionating said second liquid phase in a second fractionator at conditions to produce at least substantially bromine-free water and a second stream of bromine vapor and water vapor; andcombining the second stream of bromine vapor and water vapor generated in the second fractionator with the first stream of bromine vapor and water vapor generated in the first fractionator prior to the step of condensing. 2. The process of claim 1 wherein said substantially dry bromine liquid contains less than about 5.0 wppm water. 3. The process of claim 2 wherein said substantially dry bromine liquid contains less than about 1.0 wppm water. 4. The process of claim 3 wherein said substantially dry bromine liquid contains less than about 0.5 wppm water. 5. The process of claim 1 wherein the temperature at which such first fractionator operates is from about 40° C. to about 150° C. 6. The process of claim 1 wherein the pressure at which such first fractionator operates is from about 1.50 barg to about 10 barg. 7. The process of claim 1 wherein said substantially bromine-free water contains less than about 5.0 wppm bromine. 8. The process of claim 7 wherein said substantially bromine-free water contains less than about 1.0 wppm bromine. 9. The process of claim 8 wherein said substantially bromine-free water contains less than about 0.5 wppm bromine. 10. The process of claim 1 wherein the temperature at which such second fractionator operates is from about 100° C. to about 120° C. 11. The process of claim 1 wherein the pressure at which such second fractionator operates is from about 0.7 barg to about 1.0 barg. 12. A process comprising: fractionating a wet bromine liquid in a first fractionator at conditions to produce at least a substantially dry bromine liquid and a first stream of bromine vapor and water vapor, the wet bromine liquid being contacted with substantially dry bromine vapor in said first fractionator so as to volatilize substantially all water dissolved in the wet bromine liquid;condensing the first stream of bromine vapor and water vapor to form at least a first liquid phase comprising bromine saturated with water and a second liquid phase comprising water saturated with bromine;separating the first liquid phase and the second liquid phase; andfractionating said second liquid phase in a second fractionator at conditions to produce at least substantially bromine-free water and a second stream of bromine vapor and water vapor. 13. The process of claim 12 further comprising: heating a portion of the substantially dry bromine liquid to form at least a portion of the substantially dry bromine vapor used to contact wet bromine liquid in the first fractionator. 14. The process of claim 12 wherein said step of contacting is performed countercurrently. 15. A process comprising: fractionating a wet bromine liquid in a first fractionator at conditions to produce at least a substantially dry bromine liquid and a first stream of bromine vapor and water vapor;condensing the first stream of bromine vapor and water vapor to form at least a first liquid phase comprising bromine saturated with water and a second liquid phase comprising water saturated with bromine;separating the first liquid phase and the second liquid phase; andfractionating said second liquid phase in a second fractionator at conditions to produce at least substantially bromine-free water and a second stream of bromine vapor and water vapor, the water saturated with bromine being contacted with substantially pure water vapor in the second fractionator so as to volatilize substantially all bromine dissolved in the water. 16. The process of claim 15 further comprising: heating a portion of the substantially bromine-free water to form at least a portion of the substantially pure water vapor used to contact the water saturated with bromine in the second fractionator.
