Abstract This paper presents a predictive mathematical model of high-pressure membrane contactor, with view to developing plant-wide natural gas sweetening including amine regeneration. We build upon an existing contactor by Quek et al. [Chem Eng Res Des 132:1005–1019, 2018], which uses combination 1-d and 2-d mass-balance equations predict the CO2 absorption flux wetting under lean solvent ope...

Nitrochlorobenzenes (NCBs) are very important in the chemical industry since they have been used as raw material for the manufacture of crop protection products, as active ingredients in the pharmaceutical industry, as pigments and as antioxidants as well as for other uses. In industrial processes, NCBs are produced by monochlorobenzene (MCB) nitration reactions and one of the main residuals fo...

Conventional methods for improving the hydrophobicity of polypropylene (PP) membranes to prevent wetting phenomena require complex pretreatment procedures in order activate surface enabling reaction with fluorosilane (FS)-based materials. This study successfully prepared PP membrane contactors enhanced through a simple single-step dip-coating method using perfluoroether-grafted silanes CO2 capt...

This study evaluated the efficacy of a supercritical carbon dioxide (SCCO(2)) system with a gas-liquid porous metal contactor for eliminating Escherichia coli K12 in apple cider. Pasteurized, preservative-free apple cider was inoculated with E. coli K12 and processed using the SCCO(2) system at CO(2) concentrations of 0-10% (wt.%, g CO(2)/100g product), outlet temperatures of 34, 38, and 42 deg...

This study focuses on improving the efficiency of flue gas purification systems for carbon dioxide (CO2) capture. The researchers investigated various factors, including flow rates, absorbent concentrations, nanoparticles, and temperature, to optimize CO2 capture process. They conducted experiments using a polytetrafluoroethylene (PTFE) hollow fiber membrane contactor separate from nitrogen. pr...

Efforts to increase the mass transfer coefficient, enhance the contact area, and decrease the power input of contractors have given risen to the development of the pre-dispersed solvent extraction (PDSE) contactor and the devise of the new dissolved nitrogen PDSE (DNPDSE) contactors. The studies conducted after the design of the new contactor to determine the working conditions for its suitable...
