Exploring the Decomposition Products of 1,3,3,3Tetrafluoropropene and Perfluoro-(3-methylbutan-2-one) Gas Mixtures in Medium -Voltage Electrical Switchgear as Alternatives to SF6
(American Chemical Society, 2021-08-24)
In this work, binary and ternary gas mixtures of 1,3,3,3-tetrafluoropropene, HF0234ze(E), and perfluoro-(3-methylbutan-2-one), CF3C(0)CF(CF3)2 with CO, and synthetic air, are presented as alternatives to SF6 in medium-voltage ...
Water Reuse Study from Urban WWTPs via c-Ultrafiltration and Ozonation Technologies: Basis for Resilient Cities and Agriculture
(MDPI, 2021-02-12)
The water–development nexus is essential for the advancement and progress of cities in the face of problems such as climate change, water security and increasing environmental stress in the agricultural sector. Aiming for ...
Diffusional Behavior of New Insulating Gas Mixtures as Alternatives to the SF6-Use in Medium Voltage Switchgear
(MDPI, 2022-01-28)
Regarding the use of SF6 in medium voltage switchgear (MVS), a review of alternatives was encouraged by the European Parliament in Regulation No 517/2014. This is aimed at a new regulatory change, that is expected soon, ...
New Generation of SF6-Free Medium-Voltage Switchgear for the Electrical Network: Stability and Toxicity Studies of Trans-1,1,1,4,4,4-Hexafluorobut-2-ene with N2 Gas Mixture
(MDPI, 2023-01-03)
Binary gas mixture of N<sub>2</sub> and trans-1,1,1,4,4,4-hexafluorobut-2-ene (HFO4E) is presented as an alternative to SF6 in medium-voltage electrical equipment. Its stability was tested under different conditions. No ...
HS-SPME-GC/MS Method for the Simultaneous Determination of Trihalomethanes, Geosmin, and 2-Methylisoborneol in Water Samples
(MDPI, 2023-01-21)
Drinking water treatment plants (DWTP) use chlorination as an oxidation stage in the first step of the processes used to eliminate the natural organic matter (NOM) responsible for the formation of 2-methylisoborneol (2-MIB) ...
Stability Valorization of Hydrofluoroolefine HFO-1336mzzE and Its Mixtures under Arc Discharge Conditions
(ACS, 2024-02)
Sulfur hexafluoride (SF6) has been conventionally used as an insulating gas in switchgear. However, owing to its high Global-warming Potential (GWP), the United Nations Framework Convention on Climate Change (UNFCCC) calls ...
