In a statement to Saudi Arabia’s bourse, Tadawul, PetroRabigh said it restarted its ethane cracker after maintenance was completed, Reuters reported.

The cracker in Rabigh has an ethylene capacity of 1.6mt/yr. The cracker was taken off line early November for three weeks of maintenance work meant to ensure safety measures and stable operations at the unit. PetroRabigh had said the shutdown would have over a $99m negative impact on its fourth-quarter financial results, according to ICIS. It was the second time in recent months that the firm had shut the unit, as PetroRabigh shut the cracker down as a precaution on June 23 to work on damage to one of the unit’s turbines, restarting it on July 14.

PetroRabigh is a Saudi Arabia-based company which produces and markets refined hydrocarbon and petrochemicals. The company was a joint venture between Saudi Aramco and Japan’s Sumitomo Chemical. It utilizes 400,000b/d of crude oil and 1.2mt/y of ethane as primary feedstock to produce a variety of refined petroleum products and petrochemical products. The refinery has been producing 8mt of heavy oil, 5.3mt of light oil, 3mt of naphtha and 2.6mt of kerosene annually.
