“…Many researches in the related literature aimed at predicting the dynamics of adsorption and desorption steps of fixed bed TSA process (Ambrozek and Zwarycz-Makles, 2014;Chuang et al, 2003;Giraudet et al, 2009;Lee et al, 2011;Nastaj et al, 2006;Ncube and Su, 2012;Rezaei et al, 2014). A mathematical model describing the adsorption of VOC Downloaded by [Nanyang Technological University] at 14:58 16 June 2016 species from a gas flow onto fixed bed adsorbent and the species desorption from the spent adsorbent using an inert purge gas usually includes characteristic equations of: (i) species mass balance in the gas phase flowing through the bed, (ii) species mass balance within the adsorbent particle, (iii) heat balance in the system, (iv) species mass transfer rate, (v) species equilibrium relationship and (vi) pressure drop across the bed.…”
