Abstract

Procedimento per la separazione di paraffine in miscela con olefine che comprende:a) alimentare la miscela in fase vapore ad un'unità di adsorbimento operante con setacci molecolari in grado di presentare selettività nei confronti del doppio legame;b) scaricare la paraffina essenzialmente priva di olefina;c) desorbire l'olefina dai setacci molecolari per eluizione con un desorbente in fase vapore;d) recuperare l'olefina, in miscela con il desorbente, per distillazione.
