| titleOfInvention | Continuous preparation of polyester |
| abstract | PURPOSE: To prepare a high quality polyester, continuously, with low ethylene glycol (EG) consumption, by storing the EG discharged from the esterifying reactors and a part of the fed EG after using as circulating liquid of a wet-type condenser of a polycondensation reactor, to an EG reservoir. n CONSTITUTION: In the esterification reactors 3 and 4, the vapor of water and EG generated by the reaction is separated in a distillation column 14, and the EG is recovered in an EG reservoir 1. The esterified oligomer is polymerized in the polycondensation reactors 5, 6 and 7. The vapor of water and EG generated from the polycondensation reactor 5 is fed to a wet-type condenser 11, in which it is condensed by the heat exchange with EG pumped from an EG condensate tank 8 through a cooler 15 and sprayed into the condenser 11. The condensed EG is supplied to the EG condensate tank 8. The similar recovering process is carried out in the polycondensation reactor 6 or 7. At least a part of the fed EG is supplied to the EG reservoir through the EG condensate tanks 10, 9 and 8. n COPYRIGHT: (C)1980,JPO&Japio |
