“…It is imperative to note that lower silane‐sol particle size will result in higher mechanical strength. Similar results are observed within the literature 22,34,48 . This phenomenon was due to the coating of silane sol on ceramic membrane producing a defect free membrane with no crack growth behaviour 49 .…”

BACKGROUND: Novel hybrid absorption coupled with membrane filtration technology is proposed for the recovery of oil from produced water. This study aims at developing a low cost superhydrophobic-superoleophilic kaolin-based hollow fiber ceramic membrane using phase inversion and sintering technique for the recovery of oil from synthetic produced water. The influence of different organosialanes, such as methyltriethoxysilane (MTES), octadecyltrimethoxysilane (OTMS), 1H,1H,2H,2Hperfluorooctyltriethoxysilane (FAS), trichloro(octadecyl)silane, and chlorotrimethylsilane, was investigated for the modification process. RESULTS: Field emission scanning electron microscopy results clearly indicated that membrane morphology was altered with coating of the organosilanes. The surface functionality of the organosilanes on kaolin membranes was also confirmed by Xray photoelectron spectroscopy and Fourier-transform infrared spectroscopy. From the atomic force microscopy studies, membrane surface roughness was observed to be higher for MTES, FAS, and OTMS coated kaolin membranes. Contact analysis show that the membranes coated with MTES, FAS and OTMS organosilane agents possessed superhydrophobicity of 161.3°, 155.6°, and 150.2°as well as superoleophilicity of 0°, 1.5°, and 2.3°, respectively. CONCLUSION: Crude oil with a concentration of 2 g L −1 displayed a higher oil flux of 80 L m −2 h −1 and absorption of 90% for MTES coated kaolin membrane. This study extends the frontier of knowledge in ceramic membrane application for produced water treatment.

“…As shown in Figure 3, the mechanism of different bore fluid flow rate pre and post-sintering on the cross-section and inner microstructure of fabricated CHFMs is proposed based on previous studies performed by our research groups (Hubadillah et al 2016c;Jamalludin et al 2018). When the ceramic suspension was in contact with a coagulant (common tap water), the exchange rate of NMP (solvent) and tap water (non-solvent) bore fluid during phase separation affected the microstructure.…”

The study on ceramic hollow fibre membrane (CHFM) has been extensively explored. In this study, the CHFM was fabricated via extrusion combined with phase inversion and sintering method using silica, alumina with polyethersulfone binder and N-Methyl-2-pyrrolidone solvent at different bore fluid flow rates (10, 15 and 20 mL min-1) and sintered (1200°C). The CHFM extruded at a flow rate of 10 mL min-1 and sintered (BF10-B) showed the good porous cross-sectional hollow surface compared to the dense agglomerated surface of BF15-B and BF20-B. The highest Rq (82.1 μm) and Ra (67.8 μm) were obtained from BF10-B based on topography analysis which corresponded to the higher pore entrances of the membrane. The porosity decreased inversely proportional with the density as the bore fluid flow rate increased confirming that the suppression of un-solidified particles in the inner region cannot occur completely at a high bore fluid flow rate and produced dense membrane. The fabricated CHFM in this study has the broad potential to be applied as a membrane for water separation since it meets the minimum requirement of a commercial ceramic membrane.

“…The p-value of ANOVA assessment, which is less than 0.05, indicates that the variables have a consequential impact at a confidence level of 95 percent [17]. It is desirable to have an elevated R 2 value, close to 1, and a plausible adj R 2 adjustment is mandatory [18]. The smallest value of r was mandatory to obtain the most suitable kinds of model.…”

The Internal Combustion(IC) engine design and growth plays an important role in determining engine performance and emission features. The performance and emission properties of the spark ignition (SI) motor are also more influenced by gasoline ethanol blends. In this work, an effort has been made to optimize the operating parameters in order to minimize BSFC, CO, NO2 , CO2 , HC and maximize BTE using Response Surface Methodology (RSM). The engine is operated under constant speed conditions with different working conditions for better mixing and distinct additive composition (iso-octane) in the range of 0.3%, 0.4% and 0.5%. The appropriate RSM was used to reduce the use of petrol, its exhausts and maximize Brake Thermal Efficiency. The experimental and statistical approximation demonstrates the rise in Thermal Brake Efficiency (BTE) and decline in Specific Brake Fuel Consumption (BSFC). In addition, the chosen RSM model demonstrates reduced CO, HC, NO2 and CO2 emissions. From the assessment, it is noted that E30 mix with 0.5% additive has better motor efficiency features and reduced emissions at a peak speed of 1800rpm among all test blends with varying proportion of additives.
