SF6 (Sulfur Hexafluoride) Recovery | Hudson Technologies is widely used as an insulating and arc quenching gas in medium and high voltage transformers. As equipment ages, it is being repaired or replaced with more efficient equipment which typically uses 1/3 the quantity of SF6. This creates a need to recover the SF6 for recycling or disposal.
Panel discussion: The pros and cons of using SF6 gas in ... 6 gas is considered as a greenhouse gas, consequently release of the gas into the atmospheres should be minimised or avoided. At the end of switchgear life, the gas should be recycled and switchgears should be designed to ensure leaks are minimised as far as possible. Appropriate designs are required for easy filling and collection.
