N-alkyl imidazolium carbonate ionic liquids were employed to separate and recover naphthenic acid from model oils. The effects of the cationic and anionic structures of ionic liquids and operating conditions on the deacidification performance were…
Naphthenic acids that are naturally carboxylic compounds contained in heavy crude oil are the main source of corrosion and blockage in a crude oil pipeline. The blockage is due to the formation of naphthenate deposits through a reaction of naphthenic…
