Abstract

Ovaj pronalazak je usmeren na postupak za odvajanje poliestra, a posebno polietilentereftalata, od različitih zagadjivača i nečistoća. Uopšteno, postupak obuhvata korake mešanja materijala koji sadrže poliestar sa alkalnom kompozicijom u mikseru. Mikser daje dovoljno energije talogu da bi se obezbedilo u znatnom stepenu kompletno, ravnomerno oblaganje poliestra koji sadrži materijale sa alkalnom kompozicijom i da bi se izazvala saponifikacija spoljašnje površine poliestra sa alkalnom kompozicijom. Posle reakcije u mikseru, smeša se zagreva što dovodi do toga da je deo nečistoća hemijski modifikovan u oblik koji može lakše odvojiti. Posle zagrevanja, smeša se može isprati vodom i poliestar se može lako odvojiti od preostalih nečistoća. U postupku ovog pronalaska, poliestar se može odvojiti i regenerisati iz otpadnih materijala kao što su oni koji sadrže polivinilhlorid i aluminijum. Postupak je takodje efikasan u uklanjanju omotača koji su pripojeni za poliestar i u uklanjanju priključenih organskih i neorganskih jedinjenja koja se nalaze unutar poliestra.
