SINGAPORE (ICIS)--China’s Shanghai Huayi Group shut down its new 500,000 tonne/year acetic acid plant in Wuwei, Anhui province on 23 September, following a problem with its air separation equipment, a company official said on Monday.

The acetic acid unit was taken off line last night and it might take two or three weeks to resume,” the official said.

Shanghai Huayi also operates additional acetic acid plants in Wujing, Shanghai, under the company name Shanghai Wujing Chemical, with annual capacities of 450,000 tonnes/year and 250,000 tonnes/year.

The 450,000 tonne/year Wujing acetic acid plant is currently operating at around 90% capacity, the official added. The plant experienced an unplanned outage at the beginning of last week, following curtailed upstream carbon monoxide supply.

The smaller 250,000 tonne/year unit at the same site was shut down last week following the completion of a maintenance turnaround at the 450,000 tonne/year plant, the source added.
