In this work, the enhancement of natural gas dehydration in a tray absorber is studied. A tray by tray calculation method is used to investigate the effect of various parameters on the tray efficiency. The model provides temperature and concentration distribution of different components on each tray of absorber. The predicted data of the model were consistent with the plant data indicating the validity of the model. The result of this work showed that an increase in inlet temperature and pressure of gas would improve the overall efficiency and water dew point of gas. Also, the result of simulation showsthree in a maximum value of overall efficiency at optimum inlet gas flow rate and pressure
