SF 6 gas has excellent dielectric strength, but it causes global warming about 23900 times more than CO 2 gas which is the main cause of global warming. This shows necessity of the environment friendly dielectric gas which can replace SF 6 gas. We made the test chamber which simulated inner of the gas insulation switchgear (GIS) and 25.8kV GIS of 3 phase unity bundle operation tank type. The br...

This is a comprehensive review of the recent progresses made in the field of zeolite membranes. It describes zeolitic materials and methods of membrane fabrication, followed by a summary of applications for gas separation, pervaporation and separation of liquid mixtures. Special attention is called to polymer mixed matrix membranes (MMMs) and membranes based on metal organic frame works (MOFs)....

Hydrothermally stable particles of the metal-organic framework MIL-101(Cr) were incorporated into a polysulfone (PSF) matrix to produce mixed-matrix or composite membranes with excellent dispersion of MIL-101 particles and good adhesion within the polymer matrix. Pure gas (O2, N2, CO2 and CH4) permeation tests showed a significant increase of gas permeabilities of the mixed-matrix membranes wit...
