The acidified feed containing Bromide salts is preheated and fed to Reaction-cum-stripping tower, where Chlorine gas and steam are injected. The Chlorine gas liberates free Bromine which is stripped out by live steam in form of vapors. These vapors are condensed in a series of condensers, and condensate is collected in phase-separator. The water phase is refluxed to the tower and separated Crude. Bromine goes for distillation to remove dissolved Chlorine. Pure Bromine after distillation is collected as bottom product. This Bromine is cooled and collected in product receiver/s. A Vent condenser condenses most of the Bromine and recycles into the system. The non-condensibles are taken to the Vent scrubber. The debrominated effluent from the stripping tower exchanges heat with the feed and is relatively cooled down. It may be taken for neutralization and effluent treatment. Bromine finds its application directly and indirectly in the manufacture of pesticides, agrochemicals, pharmaceuticals, fire-retardants, photography chemicals, and many others. Bromine occurs in nature as Bromide salt present in seawater and in-land brine which is used for the grassroots production of Bromine. It is also recovered from industrial effluents/ byproducts where it occurs as different Bromide salts. Ablaze has a long and successful record of design and supply of several Bromine Recovery Plants – both grass-roots and from industrial effluents. Being manufacturer of Borosilicate Glass equipment, PTFE components and PTFE lined components, Ablaze is well qualified to handle such recovery systems as these are the major Material of Construction used in such systems. Custom made designs are offered for various Bromine Recovery Plants, depending on the source of Bromide and the end use of final product Bromine. Typical Product quality for Bromine recovered from such recovery plants is as follows: Bromine 99.5% w/w min Chlorine 0.3% w/w max Moisture 0.1% w/w max However, the system can be designed to give the desired product quality as per the customer requirement. For eg. system can be designed to give dry Bromine if so required. There are two established Processes for the Recovery of Bromine from aqueous Bromide solutions.

Bromine industry is an important part of big chemical family. Bromine and bromine compounds have wide application in different fields. Primary using of bromine compounds are in flame retardants, drilling fluids, brominated pesticides (mostly methyl bromide), and water treatment. Bromine is also used in the manufacture of dyes, insect repellents, perfumes, pharmaceuticals, and photographic chemicals. Other bromine compounds are used in a variety of applications, including chemical synthesis, mercury control, and paper manufacturing Bromine is existing in the sea bittern, as well as Industrial effluents e.g. Aq. HBr Aq. NaBr Aq. KBr. The Bromine concentration in the feedstock varies from 2 gl to 300 gl from industry to industry.

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.
