Electrodialysis process for carbon dioxide capture coupled with salinity reduction: A statistical and quantitative investigation

Latest technological advances and insights into capture and removal of hydrogen sulfide: a critical review

“…43 Absorption by alkanolamines is also widely regarded as the most mature technology for acid gas removal due to their widespread applications in the oil and gas industry. 44,45 Alkanolamine solutions such as diisopropanolamine (DIPA), methyldiethanolamine (MDEA), diethanolamine (DEA), monoethanolamine (MEA), diglycolamine (DGA), triethanolamine (TEA) and 2-amino-2-methyl-1-propanol (AMP) are widely used as solvents for dissolving H 2 S and CO 2 despite having different absorption performances. 46 Nonetheless, other types of solvents such as sodium hydroxide (NaOH), potassium carbonate (K 2 CO 3 ), sodium carbonate (Na 2 CO 3 ), sodium hypochlorite (NaClO) and piperazine (PZ) have also been used for H 2 S absorption 14,47,48 in recent years.…”

Valorization of Seawater Reverse Osmosis Brine by Monovalent Ion-Selective Membranes through Electrodialysis

“…Under these circumstances, it is essentially required to explore strategies to manage the RO brines. The conventional methods used for brine management include standard crystallizers, surface water discharge, evaporation ponds, and deep well injection [ 7 ]. Such methods, however, are generally characterized by high capital costs, negative environmental impact, or even both.…”
