A generic process modelling – LCA approach for UF membrane fabrication: Application to cellulose acetate membranes
نویسندگان
چکیده
The purpose of the research is to elaborate and implement a decision-making tool for greener membrane fabrication. scientific novelty put forth in this study generic process modelling – LCA approach applied field. resulting parameterized model allows obtain material energy flows as function operating conditions ultrafiltration hollow fibers prepared by non-solvent induced phase separation. Its modular configuration flexibility adaptation various materials industrial practices. Contributions inputs on environmental impacts can be assessed, well influence conditions. Results cellulose acetate membranes show major contributions NMP (i.e. solvent) glycerol pre-conditioning liquid). Improvement strategies mitigation include acting glycerol-related are considered within geographic context fabrication; further technical economic feasibility studies would embed these full eco-design approach. Such methodology results should taken into account elaboration “green membranes” whatever application coupled with impact use end-of-life.

In this work, cellulose acetate (CA) nanofiltration (NF) membranes were prepared via non-solvent phase inversion technique (NIPS). Polymer concentration was varied from 22 to 25 wt% in order to study its effect on the membrane properties. The fabricated membranes were characterized in terms of morphological analysis using scanning electron microscopy (SEM), contact angle, water content, water p...

Pebax-Modified Cellulose Acetate Membrane for CO2/N2 Separation
Carbon dioxide (CO2) release from the exhaust gas streams of power plants that burn fossil fuels contributes the most emission of this gas, which includes more than half of the greenhouse effects. Thus, the separation of CO2 from exhaust gases is one of the main environmental concerns. Membrane technology, due to many advantages, has attracted many research attentions among the various gas sepa...
