 Abstract
Liquid-liquid extraction is one of the most commonly used unit operation, beside distillation, for the separation of certain components from complex mixtures in refineries and petrochemicals plants. This paper reports on laboratory tests results of liquid-liquid equilibrium using for the naphta-tetraethylene glycol system. Experimental results compared favourably with those published in literature.

 Rezumat
Extracţia lichid-lichid reprezintă, pe lângă distilare, procedeul cel mai utilizat pentru separarea anumitor componenţi din amestecurile complexe de produse din rafinării şi combinate petrochimice. În acest articol se prezintă rezultatele experimentale în studiul echilibrului lichid-lichid pentru sistemul benzina nafta-tetra etilen glicol. Rezulatele experimentale sunt comparate cu cele publicate în literatură şi se constată o bună concordanţă.
