چکیده مقاله
Worldwide concerns over the threat of global warming have led industrialized countries to agree to reduce carbon emissions Transition from fossil fuels to hydrogen energy is the most practical route to satisfying the net zero emission concept Hydrogen purification is one of the most critical rings of the hydrogen energy cycle In this work a Hybrid Hydrate Amine CO2 capture process has been proposed for CO2 removal from a simulated fuel gas stream 40 mol% CO2 60 mol% H2 The process is composed from one hydrate formation dissociation stage and Amine absorption train Tetrabutylammonium bromide TBAB was selected as hydrate formation thermodynamic promoter to decrease the hydrate formation pressure An absorption/stripping process with Methyl diethanolamine MDEA solutions was applied to perform further CO2 removal from effluent gaseous stream from hydrate formation reactor The proposed processes were studied from techno economic aspects by performing energy and economic analysis The simulation results show that the duty is mainly consumed for cooling in hydrate formation reactor and steam consumption in stripper tower As the result of the economic analysis of the proposed process, total cost for CO2 capture calculated as 59 67 USD/ton CO2 that is comparable with the cost of the standalone MDEA based amine pre combustion CO2 capture process
