TEG Contactor for Moisture Removal

Saturated gas is fed to the first column CONTACT. In this column, Lean TEG using packed bed counter current operation removes moisture up to 10 ppm. of moisture in dry gas. The column works as absorber. In this column, structured packing is used for efficient moisture removal. The TEG is called as Rich TEG, after absorbing moisture. The Rich TEG is regenerated using two columns namely, Stripper and Regenerator. In stripper, moisture is removed from TEG by heating. Usually re-boiler is employed in this column. The moisture in TEG is further removed by recycling small quantity of Dry Gas generated in CONTACT.
