Abstract

A new patent co-current apparatus for gas purification from SO₂ is presented. In comparison with the counter-current gas absorbers the gas velocity in the co-current apparatus increases 5-6 times and as a result the column diameter decreases more than 2 times. The new approach for modeling of the column apparatuses is used for modeling the SO₂ absorption in the co-current apparatus. The convection-diffusion model for qualitative analysis and process mechanism identification is used. The average concentration model for quantitative analysis is presented.

Keywords: Average concentration model, co-current apparatus, convection-diffusion model, gas purification, patent, SO₂.
