Özet:
The aim of this thesis is to design and simulate a laboratory-scale CO2 capture system on Aspen Plus. The studied CO2 capture process is a post-combustion CO2 capture process. The commonly employed monoethanolamine (MEA) sorbent is compared with the piperazine (PZ) sorbent in terms of reaction kinetics and energy consumption throughout the study. Three main simulation studies were performed in order to compare MEA and PZ sorbents. First, an absorption column, then an open loop (single pass) process and finally a closed loop (recycle) process were designed and simulated on Aspen Plus. The simulations were carried out at various inlet gas pressures. After designing an absorber column, CO2 loading, temperature, pressure, mole flow, packing details, column height and diameter constraints were determined. As a result of open loop and closed loop processes, the column operations in absorber and stripper columns regarding CO2 reactions and energy consumption were investigated. The results showed that PZ absorbs and releases more CO2, has a faster kinetics, and is more energy efficient compared to MEA in CO2 capture processes.
