2018-8-15 · Sulfur Hexafluoride (SF6) is one of the most potent greenhouse gases, with a Global Warming Potential of more than 22,000 times than that of CO2. Over the past decades, manufacturers have replaced oil high-voltage switch gears with SF6-insulated units. Today, the power utility industry uses roughly 80% of all SF6 produced worldwide.

ePS04.2 Infant lung function: First report of a novel

The value of lung clearance index (LCI) is well recognised in children and adults and has also been shown to be elevated in infants with CF. At present, there are considerable technical challenges in measuring LCI in infants. There is no simple method of assessing lung function in this population.The Innocor photoacoustic gas analyser measures very low concentrations of the inert tracer gas SF6.

Facts on recycling electrical equipment waste | …

But due to the effective closed-cycle reuse process and aggressive recycling approach of the electrical industry, SF 6 remains one of the least harmful technological solutions and is the lowest contributor to global warming of the greenhouse gases. The right process: SF 6 recycling for MV and HV equipment

Infra Red SF6 Analysis – Zerowaste®

The Zerowaste® is the world’s first SF6 impurity gas analyser to coine the following features: Simultaneous SF6 measurement of up to 11 parameters uses advanced infrared absorption technology to measure SF6, H2O, HF, R12 and CF4 in addition to SO2, CO and H2S with electrochemical cell, bringing laboratory-standard measurement to the field

Plus, if the gas tank is designed in such a way that it is resistant to corrosion and can keep the SF6 gas pressurised throughout the whole lifecycle of the switchgear, then the SF6 gas can be recovered and recycled for reuse. This reduces the impact of SF6 on environment, while utilising the inherent insulating properties of the gas.
