Volume 18, Issue 3 , Autumn 2021


  Removal of Acrylonitrile (AN) from waste gas streams using biological methods has recently gained more attraction due to their better performance. The purpose of this research is modeling of the AN removal by a bio-filter. The model validation is done using the experimental data of a bench-scale bio-filter ...  Read More

2. CFD modeling and industrial evaluation of a cyclone cascade for HDPE catalyst production

Saeed Ovaysi

Volume 18, Issue 3 , Autumn 2021


  A new approach is proposed to evaluate various designs for gas-solid cyclone separators. This approach uses single-phase flow simulation results to find a quantitative measure of flow symmetry in a given cyclone. Flow symmetry is computed by averaging imbalances of non-axial velocities throughout the ...  Read More

3. Adsorption optimization of Pb(II) and Zn(II) onto the EDTA-modified MnO2/Chitosan/Fe3O4 nanocomposite from aqueous solution using RSM according to CCD method

Adel Panahadeh; Arsalan Parvareh; Mostafa Moraveji

Volume 18, Issue 3 , Autumn 2021


  Central composite design (CCD) was employed to investigate the adsorption of Pb(II) and Zn(II) metal ions as well as methylene blue (MB) as an aromatic anion by a new EDTA/MnO2/CS/Fe3O4 synthesized nanocomposite. The effect of possible affective factors including contaminant concentration (20-200 mg/L), ...  Read More
