Analysis of the CO2 Separation Process from Natural Gas Streams by Absorption with MEA using Aspen HYSYS

Abstract

The increasing concern for environmental preservation and efforts to mitigate global warming has intensified studies on process decarbonization. Simultaneously, natural gas (NG) consumption has been rising due to its lower environmental impact than other fossil fuels. To meet commercial standards, natural gas undergoes a CO2 separation stage, with amine absorption technology being the most widely used due to its industrial applicability. This study aims to organize a test spreadsheet to initiate a sensitivity analysis of the CO2 absorption process in natural gas streams based on simulations conducted using Aspen HYSYS. The analysis identifies combinations of process parameters that optimize separation results.
