Abstract
The advanced flash stripper (AFS) is proven to have benefits in capital investment and energy saving for carbon capture plants using piperazine, whilst monoethanolamine is still the most used amine in the existing commercial carbon capture plants. The production and use of energy and material consumed during CO2 absorption and regeneration generate CO2. In this research, the 130-tonne daily CO2 capture plants with conventional configuration and AFS configuration are simulated in Aspen Plus. Their total annualized costs are estimated to be 3.33 million USD and 2.87 million USD, respectively. The life cycle assessment is conducted to evaluate the environmental impacts from the cradle and grave of energy and materials consumed during carbon capture, showing 58% equivalent CO2 in flue gas is generated.
