The purpose of the TEG dehydration system of cryogenic train 4 at the Malvinas Gas processing Plant is to remove moisture content in the gas produced from /ots 88 and 56 to obtain a va/ue of less than 8 lb H20/MMSCF at the out/et. Compliance with this parameter makes it possib/e to adequately process natural gas and avoid operational problems in the cryogenic deethanation such as the formation of hydrates. The principie of operation of dehydration with TEG is the absorption of the water vapor present in the humid gas through direct contact and in countercurrent with poor glycol in equipment called an absorber or a/so called a glycol contactar. In this process, the dehydrated gas rises through the contactar and passes to a subsequent dehydration process with molecular sieves while the moisture-rich glycol passes to the regeneration system. The TEG regeneration process includes the sub-processes of separation, filtration, heating and recircu/ation of the regenerated g/yco/ for its reuse. In the regeneration process, the water removed from the glycol is condensed and transported to the water injection and treatment system. In normal operation, both the gas moisture absorption process and the glyco/ regeneration process have associated losses whose overa/l value, according to the GPSA, shou/d be in the range of 0.05 -0.15 Gal TEG/ MMSCF as evidence of proper design and operation. Therefore, a high TEG /osses indicator is evidence that one or more equipment in the absorption and!or regeneration system presents some operational functional failure or under-dimensioning that must be addressed to avoid high operating costs for TEG replacement, as well as to avoid affecting the availability and performance of downstream systems.
