Abstract
Design models of a regenerator for lean Triethylene Glycol (TEG) recovery in natural gas dehydration plants were developed from the first mass and energy balance principle. The rich TEG was heated in a heat exchanger and fed to the regenerator column. The lean TEG is recovered at the bottom of the column and recycled—the separation between TEG and water results from differences in temperature and densities of both components. The TEG dehydration plant was designed using HYSYS to obtain the design/size specification of the regenerator volume, height, diameter and area of the column as (18.857m3, 6.000m, 2.000m and 3.143m2) respectively, with 0.9250mol% of lean TEG recovery for further absorption. The results obtained show that the natural gas feed condition (temperature, pressure and flow rate) affects the performance efficiency of the regenerator and other units of the TEG dehydration plant.
