Ionic Liquid Application in Extraction of Acids

Technically, naphthenic acid have been known as one of the dynamics that are causing corrosion in petroleum industries. Naphthenic acid is the organic acid inside the crude oil which exist naturally from the aliphatic and cyclic structure inside the source rock. Nowadays,the current method of removing naphthenic acid from crude oil areinefficient because they pollute the environment and have high operating cost. This project will be focussing on the extraction of naphthenic acid from crude oil using ionic liquids through neutralisation process. Ionic liquids have been proven to extract naphthenic acid from crude oil succesfully. Basically, this project will be focusing more on the effect of different parameters on the extraction of naphthenic acidprocess using ionic liquids. The type of acid extracted from the experiment are identified for further studies on the structure because different acid structure inside the crude oil may have different effect on corrosion. This paper discussed the results of the extraction of naphthenic acid which includes the optimum parameters of the experiment.
