SF6 Gas Disposal and Recycling

Do you have unwanted SF6 gas of questionable quality at your facility? Are you looking to reduce your stockpile of SF6 gas? Let DILO Direct take it off your hands! Our SF6 gas disposal designed as an alternative to venting, destroying, or stockpiling SF6 contaminated with air, nitrogen (N2) and/or CF4.

Process of SF6 Gas Recycling and Disposal

Sulfur hexafluoride, also known as SF6, is a chemically stable, non-toxic gas. Because it has high dielectric strength and thermal stability, this gas is often used in electrical switchgear, circuit breakers, transformers, and substations.

According to the Environmental Protection Agency, the electric power industry uses about 80% of all the SF6 gas produced worldwide - and is responsible for about 70% of SF6 emissions. However, SF6 is also a potent greenhouse with high global warming potential. Thus, it needs to be carefully handled in closed systems to minimize emissions risk.

DILO Direct works with companies throughout the United States and Canada to provide safe, reliable SF6 disposal and reconditioning. We can analyze used SF6 gas for contaminants and determine if the gas can be reconditioned and reused or if it should be safely destroyed.

Using our gas separation and preparation technology, DILO can process even extremely contaminated SF6 gas to a purity level of > 99 %, exceeding IES and ASTM standards. With a thorough inspection process, DILO guarantees that each cylinder of reconditioned gas has zero by-products and <99.5 ppmV moisture content.

If a customer’s SF6 gas is too highly corrosive to be purified, it should be destroyed. Using DILO’s industrial waste treatment equipment, we will heat the SF6 gas to safely convert it into reactive fragments. The gas is converted into solid sulfates and fluorides through our chemical process.

DILO Direct Services

At DILO, we’re committed to high-quality service and best-in-class equipment to live up to our responsibility for environmental protection. We use our DILO SF6 gas separators to recondition contaminated gas and reintroduce it to the supply stream. Following the reconditioning and disposal process, we will either dispose of the cylinders or return new or re-certified cylinders. DILO Direct will receive the gas, document the quantity received, and provide complete documentation on the gas disposal for reporting purposes.
