SINGAPORE (ICIS)--Thailand’s PTT Global Chemical (PTTGC) expects at least a 15% decline in production at its crackers in Map Ta Phut because of feedstock shortage following an unexpected shutdown at a gas separation unit at the site, a company official said on Monday.
Gas separation unit No 5, which is operated by PTTGC's parent firm PTT, was shut on 14 August because of a lightning strike and is expected to be off line for three to five months.
“We may reduce the cracker operating rates by 15% or higher but the exact operating rates are not clear yet because we need to manage the LPG [liquefied petroleum gas] supply,” the official said.
PTTGC has three gas crackers at the site with a combined nameplate ethylene capacity of 1.86m tonnes/year.
Discussions are ongoing with PTT on feedstock supply, the PTTGC official said.
PTTGC's fourth cracker – I-4 No 1, which mostly feeds on naphtha – in Map Ta Phut is currently undergoing a 44-day turnaround since 1 August, the official said. The cracker has a 515,000 tonne/year capacity.
