Sea-bittern processing
Recover high-purity bromine from concentrated salt-field brine.
Solar salt production concentrates naturally occurring bromide into the residual mother liquor known as sea bittern. After salt crystallisation, the bittern commonly contains bromine in the low grams-per-litre range and can be processed economically into elemental bromine.
The hot process oxidises bromide with chlorine and strips the liberated bromine with steam. Condensation and purification then produce bromine to the required quality while the debrominated brine leaves the process. Feed concentration and flow can vary by location and season, so each plant is balanced against representative bittern data.
≥99.5% product
Purification is configured for the required commercial quality.
0.1% residual
Debromination target for brine and bromide streams.
Hot process
Efficient reactive stripping at elevated temperature.
Salient features
Designed around corrosive service and a changing natural feed.
The final equipment arrangement, materials and controls are selected around the process duty and site conditions.
Feed-characterisation led
The material balance reflects bromine content, salts, flow and seasonal variation.
Chlorine oxidation
Bromide in the bittern is converted into elemental bromine.
Steam stripping
A hot reactive column transfers bromine from brine into the vapour phase.
Separate purification
Distillation refines condensed crude bromine to the agreed specification.
Corrosion-resistant construction
Glass and glass-lined steel protect the process at temperature.
Complete plant scope
Process engineering, equipment, controls and commissioning can be integrated.
System configuration
Review the hot-process plant arrangement.
The combined reactive-stripping section handles the sea-bittern feed, followed by dedicated condensation and purification equipment.
