[ 1 ] - Effects of Permeate Pressure and Feed Flow Rate on Benzene Dehydration by Pervaporation
Membrane-based pervaporation (PV) has attracted much attention in the dehydration of organic solvents. Permeate pressure and feed flow rate are two important parameters, which affect membrane performance in pervaporation. The effects of these two parameters on the performance of a commercial poly (vinyl alcohol) membrane in the dehydration of benzene have been investigated in this work. The exp...
[ 2 ] - Preparation and Characterization of Layered Silicate Polyethylene Terephthalate Nanocomposite by in Situ Polymerization
A series of experiments on the synthesis of poly (ethylene terephthalate) (PET)/organo-montmorillonite (MMT) nanocomposites were carried out in a pressurized reactor using alkyl ammonium exchanged smectite clays, (Closite 30B).Given the degradation of organoclay at high temperatures, the in situ polymerization process was carried out at mild temperatures ranging from 210 to 230°C for 40 minutes...
[ 3 ] - Influences of Permeate Pressure and Feed Flow Rate on Benzene Removal from Gasoline by Pervaporation
In this work, the effects of permeate pressure and feed flow rate on the performance of a composite polyvinyl alcohol (PVA) membrane in the removal of benzene from gasoline by pervaporation (PV) were evaluated. The results indicate the remarkable effect of permeate pressure on membrane performance as reducing permeate pressure (higher vacuum) from 30 to 3 mmHg causes the total flux to increase ...
[ 4 ] - ALKYL IMIDAZOLINES AND THEIR ETHOXYLATED DERIVATIVES AS ANTIOXIDANTS FOR HYDROCARBON PRODUCTS
Alkyl imidazolines have been reportedly used in a wide range of industrial formulations with different applications. Ethoxylated alkyl imidazolines with appropriate ethoxylation degrees can be used as antioxidants and retarders in the formation of peroxides resulting from oxidation in hydrocarbon media. In this work, ethoxylated imidazolines were shown to be more effective in hydrocarbon media ...
