ShareRecycling greenhouse gases thanks to cryogenics
A new technology, developed and patented by ABB, enables comprehensive recycling of contaminated sulphur hexafluoride (SF6) gas by using an energy-efficient cryogenic process.
A new technology, developed and patented by ABB, enables comprehensive recycling of contaminated sulphur hexafluoride (SF6) gas by using an energy-efficient cryogenic process.
SF6 is a very potent greenhouse gas (GWP = 22 800) used extensively in the electrical industry. The purity of recycled SF6 gas using the newly developed technology is about 99.99% and is in accordance with technical grade IEC 60376 (the standard for new gas), which enables SF6 to be reused.
The greatest advantage of the new process in comparison with existing technology is that it can efficiently recycle SF6 irrespective of the type or level of contamination. Existing technologies are unable to treat all contaminants and all contamination levels in one process. The technology will be implemented at a new fully automated cryogenic SF6 purification plant in Sydney, Australia, including a novel gas separation chamber. Using recycled SF6 gas will help reduce carbon emissions and could result in a cost savings potential of up to 30%.
The company hopes the technology can be expanded to recycle contaminated natural refrigerants.
