Moreover, energy-free regeneration process using immiscible chemical additive, such as using antisolvent agents, could be promising. In this research, regeneration of industrial amines from H2S and CO2 using antisolvent has been evaluated under ambient temperature and pressure. The analysis was done by measuring the mass balance of absorbed/desorbed CO2 and H2S after antisolvent addition. The result indicated that non-polar compound, such as hexane, could have a capability to undissolve both CO2 and H2S that have been dissolved in the amine solution. The released gas per antisolvent addition ratio could reach ca. 7% for H2S and 4% for CO2 in mol basis using hexane as antisolvent agent. H2S and CO2 removal increased in proportional with the total amount anti-solvent added to the solution.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Absorption process,Acid gas,Anti-solvents,Decantation,Sweetening[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Acid gases,Amine absorption process,Antisolvent,Decantation,Sweetening[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1016/j.cep.2015.01.007[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
