Abstract
The work is part of current concerns regarding the reduction of SO2 emissions in the
atmosphere. The study aimed the SO2 retaining by absorption in dilute NaOH
solutions at different temperatures in the range of 20-60oC.
The analysed parameters were: the pressure variation of SO2 in the gaseous phase
depending on the SO2 volume injected, the degree of loading of the solution, the
pressure variation according to the degree of loading, the amount of SO2 absorbed
depending on the volume of SO2 injected and the absorption efficiency of the
solution depending on the volume of SO2 injected.
