A Novel Dynamic Model and Simulation of Gas Sweetening in Tray Beds

Abstract—Contrary to the distillation towers, much research has not been fulfilled on dynamic treatment of absorption towers. Studying on dynamic treatment of absorption towers goes back to half a century ago. In order to fulfill such a thing, we have studied dynamic and static modeling of sweetening sour gas in a tray tower by using computational software (MATLAB). In the present study, we have written a model for static condition. we have obtained the amount of CO2 mole fraction changes on each tray and pressure changes across the tower. we have determined temperature changes across the tower by writing energy balance on each tray. The result is conformed to industrial results and the used solvent is 45% MDEA. Although, in comparison with filled towers, modeling of tray towers has been less considered because of hydraulic problems and diversity in types of trays. Their modeling is so important, because of their widespread usage in industrial conditions. In order to create a dynamic simulation, we have suddenly changed the volumetric flow rate of inflow liquid solvent and the way of mole fraction changes on each tray. we have defined the exact time of getting a stable mode by fixing the number of trays.

Index Terms—Dynamic Model, modeling, sweetening, tray towers.
