Yansab is a 51 percent-owned unit of Saudi Basic Industries Corp. (SABIC), the world’s largest petrochemicals firm.

The cracker went back to normal operations on Saturday, Yansab said in a statement on the Kingdom’s bourse website citing its chairman, Mutlaq Al-Morished. It did not specify at what production rates the cracker is operating.

The unit went offline on Sept. 10 due to a technical glitch. As a result, production dropped at some units that use ethylene and propylene as a feedstock, Yansab had said in a previous bourse filing.

Yansab, which started full commercial production in March has total annual production capacity of 4 million tones of petrochemical products.
