ExxonMobil is carrying out maintenance at an unspecified unit at its Singapore Chemical Plant that has resulted in flaring.
The length of the maintenance is currently unclear.
The site is ExxonMobil's largest integrated petrochemical complex globally and has a 1.9mn t/yr ethylene production capacity, together with downstream units producing polymers.
The complex is also home to the Singapore Aromatics Recovery No.1 plant that has the capacity to produce 530,000 t/yr of paraxyelene, 580,000 t/yr of benzene, as well as 380,000 t/yr of toluene.
