But this index still had difference with the advanced level. The Yangzi company is working hard to adjust the process, and to modify the equipments to lower the AcOH consumption to 44 kg/ t.

但此指标距先进水平仍有差距，正努力调优工艺，改造设备，力争把醋酸消耗降至44kg/t。

The AcOH consumption was reduced to 54kg/ t by the means of lower temperature operation, azeotropic rectifying, by product recovery and utilization.

扬子石化采用降温操作、共沸精馏和副产物回收利用，使醋酸消耗降至54kg/t。

The AcOH consumption of PTA Plant in Yangzi Petrochemical Co. experienced the course from 100 kg/ t, 68 kg/ t to 54 kg/ t.

扬子石化PTA装置的醋酸消耗经历了从100kg/t68kg/t54kg/t的历程。

The supply and demand present situation of world polyester raw material such as PTA, EG, PX and AcOH was reviewed. The development tendency was expected.

叙述了世界聚酯原料PTA、EG、PX、AcOH的供求现状，并对发展态势进行了展望。

Reactions are generally faster in DCE than in THF, and in both solvents, reactions are faster in the presence of AcOH.

以DCE为溶剂，反应速度比在以THF为溶剂快，如果有醋酸作为催化剂，反应速度会提高许多。

It is estimated that the polyester raw material ( PTA, EG, PX, AcOH) will still in great demand in the next few years.

预计今后几年内，世界聚酯原料PTA，EG，PX和AcOH的供求仍将继续处于紧俏状态。
