Abstract
Inventia se refera la un procedeu pentru îndepartarea depunerilor de polimeri în instalatii de rectificare a hidrocarburilor de polimeri, formati din olefine si diene în procesul de distilare fractionata, prin introducerea unui solvent selectiv, format din amestec industrial de hidrocarburi C8-C20 si anume, izopropilbenzen si polialchilbenzen, la temperatura de fierbere a amestecului si la presiunea din vîrful coloanei sau la temperatura de fierbere a amestecului de hidrocarburi aromatice cu apa folosita ca antrenant si care se introduce odata cu amestecul de hidrocarburi, solventul utilizat putînd fi recuperat prin distilarea din solutie de polimer si apoi recirculat, procedeu caracterizat prin aceea ca, în scopul prevenirii formarii depunerilor formate, amestecul industrial de hidrocarburi C8-C20 se utilizeaza cu adaos de hidroperoxid de cumen si de etilbenzen.
