OPTIMIZATION OF PARAMETERS AFFECTING SEPARATION OF GAS MIXTURE OF O2, N2, CO2 AND CH4 BY PMP MEMBRANE MODIFIED WITH TIO2, ZNO AND AL2O3 NANOPARTICLES

The application of membranes in various industries is one of the most urgent needs to reduce energy consumption and environmental pollutants as well as low investment costs in the process of separation.In Toys this investigation, the optimization of effective parameters for separation of gas mixture of CH4, CO2, O2 and N2 is studied by modified pol

Traditional pump scheduling models neglect the operation reliability which directly relates with the unscheduled maintenance cost and the wear cost during the operation.Just for this, based on the assumption that the vibration directly relates with the operation reliability and the degree of wear, it could express the operation reliability as the n
