Abstract

Procedeul pentru îndepartarea depunerilor de polimeri formati din olefine si diene în instalatiile de rectificare a hidrocarburilor, consta în faptul ca în procesul de distilare, fractionata se introduce un solvent selectiv din amestec industrial dehidrocarburi C8...C20 si anume izopropilbenzen si polialchilbenzen la temperatura de fierbere a amestecului si presiunea din vîrful coloanei, sau la temperatura de fierbere a amestecului de hidrocarburi aromatice si apa folosita ca antrenant si careseintroduce oadata cu amestecul de hidrocarburi, solventul utilizat putînd fi recuperat prin distilare din solutia de polimeri si apoi se recircula. Amestecul de hidrocarburi aromate poate fi antrenat cu ajutorul vaporilor de apa introdusi direct în f ierbator.
