Membrane processes, whose low energy and operating costs make them competitive for gas separation compared to other conventional methods such as pressure swing adsorption, cryogenic distillation or amine absorption, allows high-purity be obtained in a sustainable continuous manner. Similarly, resin-derived carbon membranes with molecular sieving properties have improved the selectivity permeabi...

Although several separation technologies are technically capable of removing volatile products from fermentation broths, distillation remains the dominant technology. In this presentation, the status of an emerging membrane-based technology called pervaporation for the recovery of biofuels such as ethanol is reviewed and options for integrating pervaporation units with fermentors will be discus...

BACKGROUND This study investigates the generation of HCl and other acid gases from boiling calcium chloride dominated waters at atmospheric pressure, primarily using numerical modeling. The main focus of this investigation relates to the long-term geologic disposal of nuclear waste at Yucca Mountain, Nevada, where pore waters around waste-emplacement tunnels are expected to undergo boiling and ...

s The use of brackish water in the Saloum Delta in Senegal can be made by combining the processes of desalination as a source of solar energy, usually thermal and photovoltaic processes for membrane distillation. But the demand for energy is growing; the use of solar energy can be a good solution, given the high solar potential in these areas. Different experiences around the world have shown t...

The energy requirement of vacuum membrane distillation (VMD) with or without recirculation was modelled using both experimental results and theoretical data. The trends are generally consistent between the theoretical and experimental data. Thermal energy contributes the most to the total energy required for the VMD process. To lower the thermal energy cost, waste heat resource and heat recover...

The essential oils are frequently used in food processing industry, perfumery, cosmetics and pharmaceuticals. Most of the oils obtained by steam distillation and water distillation. It is necessary to specify the best conditions of essential oils production to get much more major compound(s) and higher yield oil. So, fennel oil was selected in this study. The objective of this work was to ident...

comin the present study, co2 removal from natural gas stream has been studied using a flat sheet membrane contactor. a three dimensional mathematical model is developed to describe the process. the model considers the transport of a gas mixture containing carbon dioxide and methane through a flat sheet membrane contactor module. the model is based on the non-wetted mode of operation, in which t...

We report on the realization of a strongly interacting quantum degenerate gas of fermionic atoms in a three-dimensional optical lattice. We prepare a bandinsulating state for a two-component Fermi gas with one atom per spin state per lattice site. Using a Feshbach resonance, we induce strong interactions between the atoms. When sweeping the magnetic field from the repulsive side towards the att...

High-temperature membranes for CO2 transport and separation has attracted significant interest from academia industries due to their potential mitigate the emissions of ultimately global warming/climate change. In this study, we report a dual-phase membrane fabricated porous proton conducting BaZr0.8Y0.2O3-δ (BZY) matrix eutectic mixture Li2CO3–Na2CO3 (denoted as MC). The exhibits high permeati...
