Bromine Recovery Plant

The Global Antico Bromine Recovery Plant is an engineered process system for the extraction and recovery of bromine from bromide-bearing aqueous streams, spent process liquors, and industrial effluents. The process follows the classical chlorination-oxidation, air stripping, and absorption-condensation route. In the oxidation stage, chlorine gas or sodium hypochlorite is dosed into the bromide-containing feed to oxidize Br⁻ ions to elemental bromine (Br₂). The liberated bromine is then stripped from solution using a counter-current air or steam stripping column, transferring Br₂ vapour into the gas phase at elevated temperature. The bromine-laden vapour is subsequently cooled through a shell-and-tube condensation system, producing liquid bromine of commercial grade purity (≥99.5%). For HBr acid output, the Br₂ vapour stream is passed through an absorption column with dilute SO₂ and water.

A dedicated tail-gas scrubbing system — typically a reducing agent (SO₂ or Na₂SO₃) scrubber — captures residual bromine from vent streams, ensuring stack bromine emissions below 10 mg/Nm³ for regulatory compliance. The plant is engineered entirely in corrosion-resistant materials including FRP structures, HDPE/PVDF piping, and graphite or glass heat exchangers, given the highly corrosive nature of bromine and HBr. Automated feed flow, oxidant dosing, and stripping air rate control ensure consistent recovery across varying feed concentrations from 0.1% to 5% Br⁻. Overall bromine recovery efficiency exceeds 95%, making the system highly effective for both resource recovery and zero-liquid-discharge (ZLD) compliance applications in pharmaceutical, flame retardant, and industrial chemical manufacturing.
