Bromine Recovery Plants

Bromine Recovery Plants

Bromine Recovery Plants are engineered systems designed to recover elemental bromine (Br?) from bromide-containing streams such as industrial waste liquors, reaction residues, salt bitterns, and spent process solutions. Bromine, being a highly reactive and valuable halogen, is widely used in pharmaceuticals, agrochemicals, dyes, flame retardants, and specialty chemicals.

During bromination reactions, only 40–50% of added bromine is consumed, while the remaining bromine exits the process as bromide salts. Bromine Recovery Plants enable efficient conversion of these bromides back into reusable bromine, improving process economics and environmental compliance.

Bromide Feed Sources

Bromine can be recovered from various bromide forms such as:

• Sodium Bromide (NaBr)
• Potassium Bromide (KBr)
• Hydrogen Bromide (HBr)
• Magnesium Bromide (Sea Bitterns)
• Spent reaction liquors and effluents

Process Description

The bromine recovery process typically involves oxidation, stripping, condensation, and purification.

Typical process steps:

1. Oxidation of bromide ions using chlorine
2. Formation of elemental bromine vapors
3. Air or steam stripping of bromine
4. Condensation in glass condensers
5. Phase separation of liquid bromine
6. Optional distillation to achieve high purity

Both cold process (for dilute feeds) and hot / steam distillation processes (for concentrated feeds) are offered depending on bromide strength.
