Life Cycle Assessment of Post-Combustion CO2 Capture and Recovery by Hydrophobic Polypropylene Cross-Flow Hollow Fiber Membrane Contactors with Activated Methyldiethanolamine

The present study evaluated the environmental impacts of post-combustion CO2 capture and recovery via membrane–gas absorption processes. We have used SimaPro v.9 packages with Ecoinvent v3.5 database employing two different methods, ReCiPe 2016 Endpoint (H) Midpoint (H), considering a fundamental methodological framework to determine most environmentally friendly experimental condition. Life cycle impact categories were examined assessed supposing functional unit 1 kgCO2/h recovered. Fourteen including global warming, ozone depletion, eutrophication, toxicity potentials been within context gate-to-gate approach focusing on only process stage. Simulation results showed that maximum liquid flow rate, sweep helium rate together minimum solvent concentration demonstrated highest human health, ecosystem, resources. usage pure methyldiethanolamine (MDEA) activated by piperazine as reactive absorbent provided lowest due elimination energy needed heat evaporate water in aqueous solutions prevention excess consumption depending meeting for tertiary amine MDEA from simulated humidified flue gas stream. highlights importance LCA determination an more sustainable condition during stripping using membrane contactors MDEA.
