| Abstract: | The main factors which have effect on unit consumption of PTA and EG from theory and production are discussed.It is pointed out that under the current production conditions,theoretical unit consumption of EG and PTA is 332.8 kg/t and 851.9 kg/t PET respectively.Unit consumption of EG is decrease and that of PTA is increased along with the increasing ofcarboxyl end group;unit consumption of PTA is decreased and that of EG is increased with the increasing of average polymerization degree.The effctive method of decreasing the unit consumption is to decrease waste product and promote the disposing efficienncy of fractionating tower. |
