insulating gas gas - WIKA Thailand

The plant safety of SF 6 gas-insulated switchgear is reduced significantly through low concentrations of decomposition products. These decomposition products arise during operation through arcing in moist or impure SF 6 gas. In order to detect even the smallest leakages or to warn ahead of gas emissions, we have a range of high-quality gas detectors and emission monitors.Get price

The decomposition products of sulfur hexafluoride (sf 6

From the environmental and health points of view, it is necessary to mitigate and control the emissions of the decomposition products from SF 6 destruction processes because most of them (e.g. S 2 F 10, SF 4 and HF) are highly reactive, corrosive and toxic, and few of them are also potent GHGs. This article aimed to introduce the fullyGet price

Decomposition of sf 6 in an RF Plasma Environment

Sulfr hexafluoride was not affected by the feed O 2 /SF 6 ratio, lead-ing to more than 99% decomposition. Reaction Products The major reaction products of the decomposition of SF 6 were SiF 4, SO 2, F 2, SO 2 F 2, SOF 2, and SOF 4. The applied power was the most important factor that limited the production of all species.13 The mole fraction of SiF 4 in-Get price

Sulfr hexafluoride Decomposition in Gas-Insulated Equipment - IEEE Journals

Abstract: The increasing application of sf 6 as an insulating gas has led to many studies on Sulfr hexafluoride decomposition in gas-insulated equipment. In the presence-of an electric arc, spark or corona, insulating gas decomposes to a wide variety of chemically active products which possess completely different properties from sf 6.Get price

Its GDP per capita of US$5,900 (3)places the country fourth in the region, behind Singapore, Brunei, and Malaysia. Relatively large domestic demand has enabled the petrochemical sector to capitalize on economies of scale. Thailand’s largest chemical and petrochemical complex is located about 200 km east of Bangkok in Map Ta Phut (MTP), in the Rayong province. It is one of the largest and best-developed petrochemical complexes in Asia (Figure 1). After the 1973 and 1979 oil shocks, the Thai government decided to develop its domestic natural gas and petrochemical industries to reduce energy imports as well as the impact of global crude oil price fluctuations on Thai petrochemical product prices. The discovery of wet natural gas reserves in the Gulf of Thailand was another key driver for industry development. This gas contains sufficient C2+molecules (ethane, pro...Get price

Thermal Decomposition Properties of Epoxy Resin in Sulfr hexafluoride - MDPI

As a promising alternative for pure sf6 gas, the mixture of sf6 gas/N2 appears to be more economic and environment-friendly on the premise of maintaining similar dielectric properties with pure sf 6. But less attention has been paid to the thermal properties of an Sulfr hexafluoride/N2 mixture, especially with insulation materials overheating happening simultaneously. In this paper, thermal decomposition propertiesGet price

Decomposition of Sulfr hexafluoride in an RF plasma environment.

Sulfur hexafluoride (SFd)-contained gas is a common pollutant emitted during the etching process used in the semiconductor industry. This study demonstrated the application of radio-frequency (RF) plasma in the decomposition of Sulfr hexafluoride. The decomposition fraction of Sulfr hexafluoride [etainsulating gas (C (in)-C (out))/C (in) x 100%] and the mole fraction profile of the products were investigated as functions of input power and feed O2/insulating gas ratio in an SiO2 reactor.Get price
