Chinese purified terephthalic acid (PTA) producer Hengli Petrochemical is planning maintenance at its No.1 unit at Dalian in mid-September.
This 2.2mn t/yr production line will be shut for a 15-day turnaround. Hengli initially planned to have this turnaround in early August, but lucrative production margins of the fiber intermediate delayed the maintenance by more than a month. Chinese domestic PTA production margin held at 970 yuan/t ($135/t) during August, around Yn400/t higher than breakeven, according to Argus data .
Hengli operates three PTA production lines in north China's Dalian with a total capacity of 6.6mn t/yr.
