1. Overview of Bromine Extraction  
Bromine is primarily extracted from brine wells or seawater through a process called blowing-out, where chlorine gas is introduced to oxidize bromide ions (Br⁻) into bromine (Br₂). The φ4 M Bromine Extraction Equipment is engineered to handle this process efficiently, ensuring high yield and minimal waste.  

Key steps in bromine extraction include:  
- Pre-treatment of brine (removal of impurities)  
- Oxidation with chlorine (converting Br⁻ to Br₂)  
- Stripping (separating bromine vapor using air or steam)  
- Condensation (cooling bromine vapor into liquid form)  
- Purification (removing residual contaminants)  

The φ4 M system optimizes these steps with advanced automation and corrosion-resistant materials.

3. Working Principle  
The φ4 M Bromine Extraction Equipment operates as follows:  
1. Brine Feed: Pre-treated brine enters the reaction column.  
2. Chlorination: Chlorine gas oxidizes bromide ions into elemental bromine.  
3. Stripping: Air/steam strips bromine vapor from the solution.  
4. Condensation: Bromine vapor is cooled and liquefied.  
5. Purification: Final distillation removes impurities.  
6. Storage: Liquid bromine is collected in sealed containers.  

The entire process is energy-efficient, with heat recovery systems reducing operational costs.
