Project Reports SF6 N2 Mixtures plant

Based on the research conducted worldwide, the optimum composition of SF6-N, mixture for practical applications is considered to be 40%SF6 - 60%N2 mixture [l, 21. Studies carried out in recent years also suggest that SF6-N, mixture with SF6 concentration as low as 20% can be used with an advantage.

  • Motion of SF+x (x=1-3,5) and ion conversion in SF6-N2 mixtures.

    This paper reports on the mass-analyzed measurement of the drift velocity of the positive SF6 daughter ions, SF+x (x=1-3,5) in the mixture of SF6 with N2 for SF6 concentrations of 10% and 50%. A double mass spectrometer-drift tube was used for these measurements.

  • A Study of the Critical Pressure in SF6/N2 Mixtures for

    Abstract: A dual photomultiplier system and a field probe have been used to study the optoelectrical phenomena in commercially pure SF6 and mixtures of SF6 with oxygen-free N2, under impulse voltages in a point-plane gap. The critical pressure has been estimated using an extrapolation technique, and the results have been compared with those of other recently published work.

  • Pure SF6 and SF6−N2 Mixture Gas Hydrates Equilibrium and

    Sulfur hexafluoride (SF6), whether pure or mixed with inexpensive inert gas, has been widely used in a variety of industrial processes, but it is one of the most potent greenhouse gases. For this reason, it is necessary to separate and/or collect it from waste gas streams. In this study, we investigated the pure SF6 and SF6−N2 mixture gas hydrates formation equilibrium as well as the gas

  • Breakdown Gradients in SF6-N2, SF6-Air and SF6-CO2 Mixtures

    Abstract: A method to calculate the uniform field breakdown gradients for SF6-N2, SF6-air and SF6-CO2 mixtures is discussed. Calculated values of the breakdown gradients in these mixtures are compared with experimentally measured values using plane-plane electrode configuration and direct applied voltages. The results show a reasonably good degree of agreement between the calculated and the measured values.

  • Separation of SF6 from Gas Mixtures Using Gas Hydrate

    Furthermore, the structure of the mixed N2 + SF6 hydrate was confirmed to be structure II via Raman spectroscopy. Through close examination of the overall experimental results, it was clearly verified that highly concentrated SF6 can be separated from gas mixtures at mild temperatures and low pressure conditions.
