Steady-state energy optimization and transition assessment in a process of CO2 absorption from natural gas

"An industrial-scale MDEA-based CO2 absorption process is considered in this work. Natural gas plant of Aguaragüe Argentina is selected to perform the studies of optimization and dynamics. With the steadystate of the process simulated, the reboiler energy demand of the plant is optimized in Asp...

Natural gas plant of Aguaragüe Argentina is selected to perform the studies of optimization and dynamics.
