Hajar seyfi; Sirous shafiei; Reza Dehghanzadeh; Parya Amirabedi

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

http://dx.doi.org/10.22034/ijche.2022.306304.1409

Abstract
  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

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

http://dx.doi.org/10.22034/ijche.2022.312897.1413

Abstract
  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
