In the current study, treatment of pharmaceutical wastewater containing penicillin G using a hollow fibre membrane contactor was investigated. A mathematical model based on finite element method developed. The extraction performed Shellsol TK as organic solvent 5% Aliquat 336. effect feed pH, flow rate and temperature were examined for from aqueous solution. results showed that there is reasona...

This study aimed to evaluate a gas-liquid membrane contactor for recovering the dissolved gases of methane (CH4) and carbon dioxide (CO2) from model aqueous anaerobic effluents. For this purpose, synthetic effluents were prepared by using gas mixtures SE-1: 100/0, SE-2: 0/100 SE-3: 50/50 CH4/CO2 vol.% as well DI water. The units in which effluent was coupled with dense hollow fiber module emplo...

In this work, a mathematical model is established to describe the removal of CO2 from gaseous mixtures including CH4 and CO2 in a polypropylene hollow fiber membrane contactor in the presence of conventional absorbents such as monoethanolamine (MEA), methyldiethanolamine (MDEA), and a blend of them. Modeling was performed in axial and radial directions under the fully-wet condition for counterc...

In this work, a comprehensive mathematical model was developed in order to evaluate the CO2 capture process microporous polypropylene hollow-fiber membrane countercurrent contactor, using monoethanolamine (MEA) as chemical solvent. terms of absorption, showed excellent agreement with experimental data published literature for wide range operating conditions (R2 > 0.96), 1–2.7 L/min gas flow ...

Raising role of the nuclear power industry, including governmental plans for the construction of first nuclear power plant in Poland, creates increasing demand for the uranium-based nuclear fuels. The project implemented by Institute of Nuclear Chemistry and Technology concerns the development of effective methods for uranium extraction from low-grade ores and phosphorites for production of yel...
