Evaluation And Sizing Of Solar Powered Reverse Osmosis Water Desalination System, Sandip Subedi
Honors Theses
About 71 % of the surface of Earth is water, out of which around 2.5 % is freshwater. The majority of the surface of Earth is occupied by seawater which also contains dissolved salt. The salt concentration in seawater makes it toxic to humans because the human body is unable to get rid of the salt that comes from seawater. The demand for fresh water is increasing due to the rise in global population. In this context, desalinated seawater is considered as a viable resource to meet the growing demand for fresh water. Desalination process is highly energy intensive due …
Biphasic Cellulose Acetate/Rtil Membranes And Functionalized Graphene Adsorbents For Natural Gas Processing: Experimental And Molecular Simulation Studies, Amir Khakpay
Electronic Theses and Dissertations
In this dissertation, gas separation using membranes is investigated for natural gas upgrading. The main objectives of this study are separation of high value hydrocarbons such as propane (c3h8) from natural gas and carbon dioxide (co2) separation from light gases such as nitrogen (n2) and methane (ch4). To achieve these goals, supported ionic liquid membranes (silms), biphasic membranes, and nanoporous graphene (npg) and graphene oxide (npgo) membranes are studied. Biphasic membranes are proposed to overcome silms issues for gas separation. The major issues with silms are low room temperature ionic liquid (rtil) content and instability at high cross-membrane pressure. For …
Designing A Membrane Module For Determining The Permeance Of High Fluxing Membranes And The Testing Rtil-Membranes For Dehumidification., Sikyun Bae
Electronic Theses and Dissertations
Membrane-based gas dehumidification can have technical energy, and economical advantages over other dehumidification technologies. Because, it is simple to install, ease to operate, and take low process cost. Removal of water vapor from gases constitutes a significant expenditure of energy in our society. Dehydration via a membrane process would constitute wide spread energy savings. This thesis explores experimental issues involved with testing Room Temperature Ionic Liquid(RTIL)-membrane for dehumidifying gases. RTIL-membranes or Supported Ionic Liquid Membranes (SILMs) have advantageous performance for the separations of the gas pair CO2/CH4 and CO2/N2. Previous research did not separate the membrane mass transport resistance the …
