Gas absorption with heat effects. I. New computational method

A dynamic simulation method was applied to det. the state of a stagewise gas absorption column. The unsteady state heat and mass balances for each real stage were integrated up to the steady state, considering all possible heat effects. The new method resulted in stable convergence of the 2-point boundary value problem. Earlier studies of the influences of typical operating and system variables on the capacity of an absorber were extended. The transport capacity of the gas phase for heat, solvent evapn., the liq.:gas ratio, the solvent feed temp., and the feed gas humidity were investigated. The limitation of the absorber capacity through the formation of a temp. plateau was confirmed and extended to the case of a column, where both absorption and desorption occur. [on SciFinder (R)]
