Abstract
Etilen je pogodna hemikalija koja se koristi kao reaktant u proizvodnji vinil acetata. Etilen je relativno skup tako da izvodjenje njegove rekuperacije i ponovne primene u postupku ohrabruje. Ovaj pronalazak predvidja postupak za rekuperaciju etilena iz struje za prečišćavanje inertnog gasa iz kola reaktora u parofaznom postupku za pravljenje vinil acetata. Postupak ovog pronalaska uključuje faze dovodjenja u dodir struje inertnog gasa koja sadrži etilen sa sirćetnom kiselinom u apsorpcionom sudu; ispuštanje struje koja sadrži sirćetnu kiselinu i etilen iz jednog položaja apsorpcionog suda; odvajanje etilena od sirćetne kiseline u struji dovodjenjem u dodir struje sa etilenskim gasom u koloni za prečišćavanje; i rekuperacija etilena sa vrha kolone za prečišćavanje. Postupak može takodje da uključuje fazu recirkulacije rekuperisanog etilena u kolo reaktora za dalju upotrebu.
