Industrial Electrolysis Technologies
Industrial electrolysis technologies are divided into several types:
- PFPB - Electrolysis technology using burnt anodes and point feeders
- CWPB - Electrolysis Using Burnt Anodes and Center Bursting Beams
- SWPB - peripheral processing of electrolyzers with baked anodes
- VSS - Soderberg technology with top current lead
- HSS - Soderberg technology with lateral current supply
Comparison of production volumes in the aluminum industry
Results of studying aluminum production volumes using various industrial electrolysis technologies conducted by the IAI Institute in 2001 [1] (manufacturers from Russia and China are not included in the survey).
| Technology | World production (tons) | The volume of production of survey participants (in tons) | Percentage of survey participants |
|---|---|---|---|
| Pfpb | 14172142 | 11795764 | 83,2 |
| CWPB | 2224778 | 1210676 | 54,4 |
| SWPB | 1450260 | 647846 | 44.7 |
| Vss | 4321015 | 1803941 | 41.7 |
| Hss | 2320280 | 469280 | 20,2 |
| Total: | 24488474 | 15927306 | 65.0 |
Environmental Impact
The largest volume of specific emissions from electrolysis cells is accounted for by electrolysis processes, which are based on Soderberg technology. This technology is most widely used in aluminum plants in Russia and China. The volume of specific emissions from such electrolyzers is much higher relative to other technologies. The number of fluorocarbon emissions is also reduced by studying the technological parameters of the anode effect, the reduction of which also affects the amount of emissions.
