Bromine being a highly reactive material, finds wide applications in many Chemical Industries like, Organic Intermediates, Dyestuffs, Agrochemical, Fire retardants etc.
The feed is acidified with 30% HCl acid and acidified feed is fed to the scrubber by pump to Scrub uncondensed chlorine from Vent Condenser and return back to the reaction column. In some cases the part feed is preheated using effluent from the reaction column prior to the entry of reaction column and part feed is fed to the scrubber to conserve energy. Chlorine and Steam are also fed to the reaction Column.
In the reaction column the feed is reacted with chlorine gas & bromine is liberated Instantly. This liberated bromine is stripped out of the solution by live steam. The bromine and water vapor stream leaves the top of the column and enters the condenser. Condensate falls into the Phase Separator where it forms two phases, the light aqueous phase (Water) being returned to the Column ,while the heavy phase(Bromine) being feed the purification column. Cooling Water & Chilled Water is used as cooling media in heat exchanger provided at the top of the column to condense water vapor & Bromine.
Purification of the Bromine is achieved by distillation. Heat being introduced into the column through the reboiler. Bromine and Chlorine vapor leave the top of the Column and enter the Condenser .The Bromine gets condensed in the Condenser and falls back into the column while uncondensed chlorine vapor along with traces of Bromine escapes from the Condenser and enter into the Vent Condenser, where remaining Bromine gets condensed and back to the crude Bromine receiver. Pure bromine is cooled in a product cooler and goes to Product receivers. Guard condenser is also provided at the top of the receiver to prevent escape of bromine. Bromine is then collected in glass bottles.
From Industrial Effluents (NaBr/KBr/HBr) From Sea -Bittern . Available up to 600 mm Dia.
Over View of the System
The system consists of:
- Stripping /Reaction Column – Glass
- Cooling/Chilling Heat Exchangers Phase Separator – Glass
- Bromine Purification Column Pure Bromine Condenser -Glass
- Vent / Guard Condenser – Glass
- Bromine Reboiler – Glass

Raw Material Requirement
- Sea- Bittern (Brine)/ NaBr /KBr
- Chlorine Gas
- 30% HCl
- Bromine Liquid : 99.7% (w/w, min)
- Chlorine : 0.3 % (w/w, max)
Bromine can be recovered from two sources
- From Sea Bitterns
- From Industrial effluents
We offers turnkey projects for the recovery of Bromine from both the aforesaid sources.
Two processes are generally adopted for the recovery of Bromine from Sea/ Salt Bittern as mentioned below:
a) Steaming Out Process (Hot Process)
The process is also known as Hot Process because chlorination of bittern is done with simultaneous steam blowing by means of live steam to heat the bittern to near its boiling point to set free the finished product Bromine.
b) Air Blowing Process (Cold Process)
This process is known as Cold Process because the finished product Bromine is set free from bittern by chlorination and air blowing under cold conditions.
Aqueous Bromide solution is reacted with chlorine vapour in reaction column. The Chlorine liberates elemental bromine from the dissolved bromide. This is stripped out by live steam feed from the bottom of column.
Crude bromine is then distilled to get Bromine purity of minimum 99.5%. The solution is not always so simple though, as feeds are often contaminated with organic material from process. These organic impurities have to be removed by pre-treatment before feeding to the plant.
Typical plant consists of stripping column, Heat Exchangers Phase Separator, Purification Column collection pot, Reboiler, Scrubber with associated Glass Piping and Fittings. All wefted components are made from Borosilicate glass and PTFE which are corrosion resistant even at elevated temperature.
