Hot Process Bromine Recovery Plant, for Industrial

Listing ID #5562856

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.
