Simulation of carbon dioxide capture from syngas at a GTL plant: A parametric Study

In this work, a CO2 capture unit from syngas stream of a GTL plant was simulated. Amine solvents were selected as the most promising technology for CO2 separation. The main goal of the unit is to reduce at least 90% of CO2 from the feed stream. Three different amines (MEA, MDEA, DGA) have been compared in order to find the solvent with lower energy consumption and higher CO2 capture capacity. MEA and MDEA show good performance for capturing CO2 and consume less energy then DGA.
