• The existing problem in the natural gas plant is a large amount of water vapor in the pipeline. The water content in the natural gas component reaches 0.3192 weight fraction from the well. The chemical separation in the separator still has a 0.0019 - mole fraction of water, and water content is up to 19.54 lbs/mmscf. The permissible water vapor content in the gas plant is less than 15 lbs/mmscf, which is under pipe specifications. Therefore, it is necessary to carry out a gas dehydration process to reduce the water vapor content of natural gas by the absorption method using triethylene glycol (TEG) absorbents. The research was conducted to determine the impact of temperature, pressure, and purity of lean TEG in reducing water content in the contactor using a commercial simulator. Based on the data obtained at lean TEG 100 is up to 10.03 lbs/mmscf. The sensitivity simulation shows that the lean TEG 90℉ temperature has the lowest water content of 1.012 lbs/mmscf. Meanwhile, with a pressure of 875 psi, the total water content is 1.170 lbs/mmscf. Finally, 99% TEG, a water content of 0.314 lbs/mmscf, is obtained.
