Amine plant simulation by mass transfer and kinetic approach
A computer program has been developed for the simulation of gas-liquid absorption columns. The calculations are based on known assumptions and methods - the two-film theory. Mass and energy balances together with chemical reactions are carried out for each tray of the column. The results obtained from the simulation procedure are compared with those measured at industrial plants. For the items ''rich solution temperature'' and ''calculated number of trays'' the agreement of calculated and measured results are satisfactory. However, for the CO2 and H2S content of the streams only few comparisons could be made due to the fact that no measured values are available.
