Saudi Arabia’s PetroRabigh will restart most operations at its refining and petrochemical complex on December 3rd, after a 50-day maintenance work, while high olefin cracker unit will remain offline until estimated end-December, Trade Arabia reported.

The company is yet to announce the exact financial cost of the maintenance work, but it was reported that the offline period would cut company’s gross profit by estimated $240m in Q4, GDN Online wrote.

PetroRabigh is a joint venture between Saudi Aramco and Japan’s Sumitomo Chemical.
