Resumen: The energy transition to renewable sources is crucial for reducing CO2 emissions. However, full decarbonization by 2050 faces challenges, with natural gas being a key source with the lowest environmental impact. This study analyzes the natural gas liquids (NGL) recovery process in Brazil, highlighting the use of the Gas Subcooled Process (GSP), which is widely used in the country due to its flexibility in recovering products such as methane, ethane, propane, and natural gasoline (C5+). Exergy and exergoeconomic analyses are performed on different processing arrangements (Turbo Expander TE, Joule-Thompson JT, and as an addition of mechanical refrigeration TEMR and JTMR), along with other natural gas compositions in the feed, focusing on optimizing energy efficiency and reducing operating costs. The arrangement with turbo expansion (TE) was found to have the highest exergy efficiency at 71.41%, while mechanical refrigeration demonstrated better performance for rich gas streams. Equipment such as the Joule-Thompson valve and air coolers presented low exergoeconomic factors, suggesting the need for improvements. By reinforcing the role of natural gas in the Brazilian energy sector transition, this research contributes to developing more efficient and sustainable processing units.
