Psychrometric-like charts for the energy analysis of VOC recovery processes

“…. ) with respect to the charts developed by Shallcross or Shallcross and Low [7][8][9], but taking into account the adsorption equilibrium in the drawing, a reasonable accuracy is obtained when compared to a full numerical simulation of the adsorbers [12]. These charts can be viewed as a new convenient tool for the energy analysis of integrated VOC treatment processes including condensation and temperature-driven adsorbers.…”

“…Section 4). On the contrary, if choosing a conventional scale, the overall shapes of the line is directly comparable to the moist-air chart, as shown by Shallcross [9].…”

“…The choice of the state equations (Virial formulation, excess variables in order to take into account the non-ideality of such mixtures) was also discussed by Shallcross [8]. Recently, this author extended the development of such psychrometric-like charts to various ketones-dry air systems [9]. These charts were however not used for describing unitary operations but rather to analyse the thermodynamic equilibrium.…”
