Abstract

According to the importance of water vapor available in the natural gas, achieving a powerful absorbent looks quite necessary. In this study, for the first time, tetraethylene glycol (TREG) and its mixture with triethylene glycol (TEG) were used to remove water vapor from a wet air stream. Following this, to achieve a good vision about the performance of TREG, the results were compared with the pure TEG and the impact of gas flow rate was considered. Based on the obtained results, all absorbents applied in this work resulted in a better performance in lower gas flow rates. Further, although TEG was the best absorbent at low gas flow rates, TREG had the best performance in water vapor removal at high gas flow rates. Finally, in the best operational condition in this work, the use of TEG led to the reduction of water vapor from 90% to about 10% at 60 ml. min-1. However, applying TERG had a better result at 120 ml. min-1 and caused the water vapor to reduce from 90% to approximately 5%. High water vapor absorption in high flow rates indicates the high capability of TREG to employ in gas dehydration processes in industrial scales.
