Mathematical Modeling and Parameters Optimization of the Degradation of Acrylonitrile in Biofilters

Hajar seyfi; Sirous shafiei; Reza Dehghanzadeh; Parya Amirabedi

Volume 18, Issue 3 , September 2021, Pages 3-15


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

CFD Modeling and Industrial Evaluation of a Cyclone Cascade for the Production of the HDPE Catalyst

Saeed Ovaysi

Volume 18, Issue 3 , September 2021, Pages 74-85


  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 ...  Read More
