PTT Global Chemical PCL , Thailand's largest petrochemical maker, has shut down for maintenance its olefins plant I-4/1 for 21 days from March 29, ahead of schedule, as per a statement in Reuters. The shutdown, earlier planned for August, which involves cleaning up quench oil tower, will allow the plant to boost its efficiency faster and suit with the market situation. The shutdown has also led to PTT Global's by-product value-added unit, which uses feedstock from the olefins plant, to be closed during the same period. The shutdowns will not have significant impact on the company's performance, it said.
The olefins plant has annual production capacity of 515,000 tons of ethylene and 310,000 tons of propylene while the by-product unit has an annual capacity of 75,000 tons of butadiene and 25,000 tons of butene.
PTT Global had earlier planned shutdown of the olefins plant I-4/1 for 21 days during Aug. 20-Sep. 9. It also plans to shut down another olefins plant I-4/2 for 35 days during June 27-
