Chinese producer SP Chemical has yet to achieve on-specification ethylene at its new Taixing 700,000 t/yr LPG-based cracker.
The plant in east China's Jiangsu province is now expected to achieve on-specification product by the end of August. Trial runs started earlier this month, with the producer feeding in propane as the feedstock.
Ethylene production has started at the new cracker but it is still unstable. Operating rates are currently at around 90pc. The new cracker is also able to produce 244,000 t/yr of propylene.
Ethylene produced at the cracker will be used at its downstream 320,000 t/yr styrene monomer and 360,000 t/yr ethylene dichloride plants. Propylene produced at the new plant will be all for merchant sale.
SP Chemical is also still trying to buy ethylene from the merchant market for downstream use, said a regional market participant.
Ethylene spot prices in China weakened since late last week with deals done in a $900-930/t cfr range. Buyers have withdrawn to the market sidelines as they await news of on-specification production at SP Chemicals' new cracker. Regional supplies in southeast Asia, South Korea and Taiwan continue to be tight.
