Industrial Counter-current Column Absorber

Abstract

In Chap. 11 were presented the convection–diffusion and average-concentration models (Boyadjiev in Theoretical chemical engineering. Modeling and simulation. Springer, Berlin, 2010) [1], (Doichinova and Boyadjiev in Int J Heat Mass Transfer 55:6705–6715, 2012) [2] and (Boyadjiev in J Pure Appl Math: Adv Appl 10(2):131–150, 2013) [3] of the gas absorption processes in the co-current columns, where the radial velocity component is not equal to zero, in the cases of an axial modification of the axial velocity radial non-uniformity along the column height (Boyadjiev in Bulg Chem Commun 49(3):711–719, 2017) [4]. This possibility will be used for modeling of the gas absorption processes in the counter-current columns, where the problem is complicated (Boyadjiev in J Eng Thermophys 24(3):247–258, 2015) [5], (Boyadjiev in Bulg Chem Commun 49(3):720–728, 2017) [6] because the mass transfer process models have to be presented in two-coordinate systems (in a one-coordinate system, one of the equations has no solution due to the negative Laplacian value).
