Aster Chemicals declares force majeure at Singapore naphtha cracker

Singapore's Aster Chemicals and Energy has declared force majeure on petrochemical supplies from its naphtha cracker on Bukom island.
In the letter, the company attributed the force majeure to an "unforeseen event" at its ethylene cracker complex, which has been under planned maintenance since August 1.
It remains unclear how long the 1.1-million-ton-per-year (tpy) unit will be shut, though sources with direct knowledge of the matter said the original restart date was the first half of September.
A steam cracker typically breaks down naphtha into petrochemical products such as ethylene and propylene, both building blocks for plastic materials. The crude distillation units with a total processing capacity of 237,000 barrels per day (bpd) at this Bukom site will continue running at slightly reduced rates because of this issue, two sources with direct knowledge of the matter said.
